Abstract

This study is intended to examine the operation of a sheet-fed offset press, the problems and their

causes and the strategic management required to prevent operating problems or find possible

solutions. A sheet-fed offset press is designed to print a single sheet of paper at a time.

The problems encountered on a sheet-fed offset press are related to inking, dampening, operating,

paper and machine maintenance. This study considers the relevance of make- ready and machine

maintenance policy for printing companies.

The dissertation also focuses on how strategic management decisions could prevent, detect or solve

printing-related problems and how print quality could be improved so that customer satisfaction can

be achieved.

The research methodologies that will be used in this study are questionnaire and press observation.

CHAPTER ONE

1.1 Introduction

This dissertation examines sheet- fed lithographic printing operations, the press, operational units

and press maintenance. Dejidas and Destree claim that `the modern offset lithographic is the

product of a range of historic technological innovations` (Dejidas and Destree, 2005, p.3). A sheet-

fed offset press is a printing machine that prints consecutive single pages; it uses the offset

principle to carry out printing operations on the substrate. Dejidas and Destree further state that

`an offset press...is a mechanical device that dampens and inks the printing plate and transfers

the inked image to the blanket and then to the printing substrate´ (p. 16). The image area is ink

receptive, while the non-image area is water receptive.

The author suggested that there are many problems associated with sheet-fed press print operations,

such as registration, paper quality, relative humidity, ink distribution, printing unit and so on. The

author will examine these factors and, through the primary and secondary research, identify the

causes and the remedies. Martinich defines operation management as, `a discipline and profession

that studies (and practices) the process of planning, designing and operating production systems and

subsystems to achieve the goals of the organization` (Martinich, 1997, p.10). As the Six Sigma roadmap

is used to detect and remove defects and to assist with quality standards improvement, the author

will also use the roadmap to define, measure, analyse and improve sheet-fed offset operations.

Print problems on a sheet-fed offset press may be caused by press operation, the materials (paper)

that come together in the press or as result of any situation that occurs, either by accident or

operator`s error, during the press run. In addition, the problem could also be a combination of many

factors, such as mechanical, chemical and physical variables. Therefore, the ability to identify and

control these variables as quickly as possible, during make-ready or press operation, will reduce

downtime and increase efficiency, effectiveness, productivity and profitability.

The problems encountered on a sheet-fed offset press are related to inking, dampening, operating

and paper and machine maintenance. This study will consider the relevance of strategic operation

management and its application, along with machine maintenance policy for enhancing print quality.

question is:

Can controlling printing variables during make- ready reduce downtime and increase efficiency,

effectiveness, productivity and profitability?

1.3 Aim This study aims to identify the various factors responsible for poor quality of print products on a sheet-

fed offset press as well as how the print problems and the make-ready on a sheet-fed offset press

could be defined, measured, analysed, improved and controlled.

1.4 Objective The objective of this study is to examine how operational management strategy can improve print

quality and customer satisfaction, and also to create a means to improve print product specifications.

CHAPTER TWO LITERATURE REVIEW

2.1 INTRODUCTION

This chapter begins with the background to this study, Sheet-fed Offset Press Operating: the Importance

of Strategic Operation Management. The author will review different literatures and discuss the

different opinions and assertions made by the authors within the area of sheet-fed offset printing,

operation and strategic management.

2.2 SHEET-FED OFFSET LITHOGRAPHIC PRESSES

Hird asserts that `the different brands and models vary in certain details of construction, operating

controls, cylinder arrangements, feeding, and delivery. However, the principles of operations are

basically the same for all offset printing machines ` (Hird, 2000, p.451). Sheet-fed offset presses are

designed of units and ‘sheet travels between plate, blanket and impression cylinders with the aid of

`chain grippers`’ (Speirs: 1992). Since a sheet-fed offset press consists of printing unit, inking unit,

dampening unit, delivery unit and feeding unit as well as sheet registration system and other mechanical

components, this study will explore these printing units and their components, press condition and

machine maintenance. Defining the lithographic process, Kipphan says:

`here, printing and non- printing elements are at the same planographic level but are usually made from

different chemical and physical surface properties. During printing, non- printing elements are usually

made ink repellent first (by wetting) and plate is then inked so that the ink is taken up only by the

printing areas.’ (Kipphan, 2001, p.30).

Speirs asserts that `the printing and non- printing surfaces are to all intents and purposes on the same

plane and the substrate is pressed into contact with the whole surface` (Speirs, 1992, p.8). According to

Dilworth, ´the scope of operations is broader than some readers may initially have in mind. In a

manufacturing company, for example, operations is much broader than just the activities that occur in

the factory’ He adds, ´we consider the operations function an integrated system that obtains the

Page 16: Sheet fed offset press operating: Importance  of Strategic Operation Management

16

necessary inputs, transforms them to make them desirable to the customer`( Dilworth, 1996, p.3) In the

printing industry, lithographic offset operation is different from letter press relief process. In the

lithographic process, the image and non-image areas are on the same level so that no image is raised

above the other, unlike in the letter press relief method. The sheet-fed offset lithographic process, its

structure, properties and the interaction between the water, ink and substrate (paper) are explored in this

study to show how important these elements are in reducing downtime and increasing the efficiency,

effectiveness, productivity and profitability.

Edvardsson et al. assert: ´production should always be seen in relation to quality and profitability`

Although `productivity and quality are both concerned with income as well as expenditure and tied-up

capital, there is a different emphasis` (Edvardsson et al., 1994, p.26) Lloyds et al. state: ‘Among the

requirements for successful press operation is the smooth and consistent flow of paper through the

press` (Lloyds et al., 1987, p.7). Paper is made from pulp and used to write or print on. Therefore, a

good quality paper flows easily at the press and prevents press problems of any kind. However,

operational problems are not limited to paper or its characteristics alone. In other words, press operating

problems could arise from the printing unit, ink and feeding distribution, plate dampening, plate and

press, offset blanket, ink or paper. The consistency and free flow of paper on a sheet-fed offset press is

part of the `requirements for successful press operation` (GATF staff, 1994). The printing unit of a

sheet-fed offset press contains three cylinders, plate cylinder, blanket cylinder and impression cylinder.

The plate on the plate cylinder receives the inked images in right reading, transfers them to a rubber

covered blanket (offset) and subsequently to the substrate under high pressure. Dejidas and Destree

argue that `the plate was the most important source of problems in lithography during the first half of

the twentieth century` (Dejidas and Destree, 2005, p.11). If the plate lacked affinity for ink, it would

fail to print in either one colour or full colour (CMYK) process on a sheet-fed offset press. Hird asserts

that `today, offset lithography relies not only on quality chemicals, films, inks, papers, plates, and

related materials, it also depends on computer technology`. He adds that `skilled personnel are needed

at every stage of the process to perform high-quality colour printing on fast precision presses` (Hird,

2000, p.25). In quality service, Dilworth asserts that, ́ quality is encouraged at all stages of the operation`

(Dilworth, 1996, p.36). High-Tech offset presses (automated presses), qualified press operators and

quality materials play significant roles in achieving efficiency, effectiveness and productivity in a sheet-

fed offset operation.

Edvardsson et al. claim that ´a noticeable shortcoming in many studies of productivity is that they do

not take quality and income into account` (Edvardsson et al., 1994, p.27). Bann states that `offset litho

requires minimal make-ready and the rubber blanket compensates for differences in the surfaces being

printed by adapting itself to the profile of the material´ (Bann, 2006, p.88). One the reasons that an

intermediary cylinder carrying the rubber blanket is used on sheet-fed offset lithographic presses is to

Page 17: Sheet fed offset press operating: Importance  of Strategic Operation Management

17

prevent the metallic lithographic plates from having direct contact with the substrate (paper). According

to Johnston and Clark ‘Process design describes and prescribes the procedures to be followed in service

delivery and also how they will use or interact with other resources such as materials or equipment`

(Johnston and Clark, 2005, p.171).

Therefore wear and tear of the lithographic plates during press operation can be reduced and, in turn,

produce quality prints that will be acceptable to the customers. Modern sheet-fed offset lithographic

presses have automated control devices to `adjust` and regulate inks and colour registrations and also

to `reduce make-ready` (Bann: 2006). According to Hird, `make-ready covers all the activities the press

operator performs between starting the job and running the job` (Hird, 2005, p.496).

Industry Week website identifies five keys to effective operating problem-solving techniques: Focus on

root cause (s) not symptoms; turn-off all root causes; don´t mistake containment for resolution; audit

result of problem-solving; and, don´t over adjust. When ink and paper are not compatible, sheet-fed

press operating problems develop and this will prolong the operational time in the press and also mar

the print quality. However, the problem can be corrected by changing either the paper or the ink, as the

paper may be too acidic or dusty or the ink may be too tacky.

Hill and Hill state that, ´operations management contributes hugely to business success-and if managed

badly, it can lead to disaster`( Hill and Hill, 2011, p.3) The problems could derive from various sources:

the printing unit, such as uneven impression, marking of the printed sheet, doubling or misregistration;

from the sheet feeding and delivery, such as feeder misses, sheet jam on the conveyor, side guide or

sheet fail; from ink feeding and distribution, such as uneven ink feeds ]; from inking, such as hickeys,

ink drying too slowly, scumming, set-off, slur or colour fades; or from the paper, such as creasing, white

spots, etc..

The study will consider the primary and secondary research. Marchington and Wilkinson assert ´this is

particularly pertinent in the service sector where workers are the primary source of contact with

customers` (Marchington and Wilkinson, 2012, p.4). To determine the causes and remedies of all press

problems so they can be corrected or prevented as soon as possible. They add ´the way in which human

resources are managed is seen as an increasingly critical component in the production process, primarily

in terms s of quality and reliability` (p.44). This study will explore and assess the importance of strategic

management in the area of sheet-fed press operation and how it helps printing companies to achieve

their organisational goals and objectives.

It is important to identify and evaluate ‘what is to be managed` (Porter: 1993). This study will also

identify and examine the various problems associated with print operations on a sheet-fed press as well

Page 18: Sheet fed offset press operating: Importance  of Strategic Operation Management

18

as exploring how strategic planning could provide answers to the problems. According to David,

`strategy formulation is positioning forces before the action` and that `strategy implementation is

managing forces during the action` (David, 2013, p. 243).

If strategy management is about formulation, implementation and evaluation of strategic ideas, then the

author intends to predict, identify and examine the likely causes of printing problems on a sheet-fed

offset press as well as putting all necessary strategic solutions in place to manage the problems during

operation.

The study focuses on the sheet-fed press operating system, operating problems, paper, image carrier

and the strategic management of how print quality, efficiency and printability can be improved. For any

printing company to remain in business, customer satisfaction is a must; therefore, quality printing

promotes customer loyalty.

This inspired the author to choose this topic and to critically examine the problems, causes and possible

remedies in sheet-fed press operations.

2.3 THE SIX MAJOR OPERATING UNITS OF OFFSET LITHOGRAPHIC

PRESSES According to Hird (2005), offset presses are divided into six major operating units, namely:

(1) Feeding unit

(2) Register Board and Insertion unit

(3) Printing unit

(4) Inking unit

(5) Dampening unit

(6) Delivery unit

2.4 FEEDING UNIT This is a unit whereby a sheet of substrate (paper) is fed into the press, either continuously or

successively. It has a feed board, conveyor belts, front guides, side guides, suckers and double sheet

detector. The sheets of paper move from the feed board, and the position is adjusted by the front guides

and side guides. The front guides are the mechanisms that control the sheet`s movement from the front

and position it in line with the plate cylinder, while the side guides push or pull the sheet by the side for

its proper alignment. Through the suckers and other infeed systems, the sheet of paper is sucked and

moved from the feed board to grippers on the impression cylinder.

Page 19: Sheet fed offset press operating: Importance  of Strategic Operation Management

19

The front guides square the sheet of paper in relation to the impression cylinder and determine the front

margin for press registration. Kipphan states that `the feed system has the task of picking up the sheets

from the feed pile, separating them, conveying them to the feed table via a feed system, and aligning

them at the feed guides`( Kipphan, 2001, p. 229). However, improper positioning of the sheet on offset

presses could lead to poor registration of a multi-colour job. A continuous sheet feeding system is

known as stream feeders and a successive feeding system is known as single-sheet feeders. This feeds

one sheet at a time, but a continuous sheet feeding system allows the rear sheet edge of each sheet of

substrate to overlap the front edge of the preceding sheet while on the feed board.

2.5 REGISTER BOARD AND INSERTION UNIT After the sheet of substrate is lifted up and moved from the feeding unit, a register board and insertion

mechanism take control and insert it into the register for the actual printing operation (Hird: 2005). To

register sheets of substrate on sheet-fed offset presses, the sheet must be properly aligned with regard

to the image on the printing unit. The registering mechanism must be controlled and adjusted on sheet-

fed offset presses to achieve single or multi-colour registration.

Hird identifies three types of press register and insertion methods: three-point guide system, the feed-

roll system and the swing-feed system. According to Kipphan, `the infeed system now has the task of

bringing the sheet, guided accurately in grippers, up to production speed and passing it on to the grippers

of the impression cylinder` (Kipphan , 2001, p. 236.) It is important that each and every sheet of

substrate must be in a correct and accurate position throughout the press cycle. The insertion control

devices are now adjusted automatically on sheet-fed offset presses, which reduces machine downtime

and production time during press operation.

2.6 PRINTING UNIT This is the `heart` of the sheet offset press because every single thing about press operations and actual

printing is determined in this unit (Hird: 2000). This unit consists of three cylinders: plate cylinder,

blanket cylinder and impression cylinder. The parts of a plate cylinder include the main body, gears,

bearings and the bearers that keep the cylinder in motion. The plate cylinder accommodates the

lithographic plate, and the image on the plate is right reading. The image on the lithographic plate and

the non-image area are on the same level, and the image area is made to accept ink while the non-image

area is made to accept water. It has front and back plate clamps, with the front clamp holding the leading

edge of the plate while the back clamp holds the tail edge of the plate securely. According to Kipphan

(Kipphan, 2001, p. 241):

‘The printing plate is clamped in the plate cylinder gap by two clamping bars. The cylinders on sheet-

fed offset presses usually have a wide gap, thereby offering good accessibility for manual mounting of

Page 20: Sheet fed offset press operating: Importance  of Strategic Operation Management

20

the plates. Thanks to modern set-up technology, register errors occurring during assembly, platemaking,

and plate clamping are so minor that accurate positioning can be achieved by circumferential, lateral,

and diagonal register adjustments via the control console without stopping the press.’

Since the blanket cylinder holds the rubber blanket, the rubber blanket receives the image from the plate

cylinder and transfers the image onto the sheet while the blanket cylinder is pressed against the

impression cylinder.

2.7 THE CHARASTERISTIC OF SHEET-FED OFFSET LITHOGRAPHY. The Print and Production Manual (Smyth, 2003, p. 217) identifies the following as the features of offset

lithography:

(a) No impression or squash is apparent at the edge of type, which is sharp even at small point sizes

(b) Thinner ink-film than the other processes

(c) Good uniform ink-coverage density in the image areas, even on rough paper

(d) Good uniform halftone printing with smooth vignettes, even on rough paper

(e) Halftone tones will normally be at a finer screen ruling than other processes on similar substrates

(f) Halftone dots may appear circular, elliptical or square in midtones

(g) Small specks of ink may be apparent in non-printing areas, but are less common with CTP

(h) Under magnification, it may be possible to see evidence of doubling

(i) Conventional oxidation drying inks have a characteristic oil-based odour when books or brochures

are opened

Dejidas and Destree remind us that `a variety of sheet-fed printing presses are available…….For sheet-

fed offset lithographic printing, there are three basic press configurations` (Dejidas and Destree, 2005,

p.18). These press configuration are: Single–colour sheet-fed press, Multicolour sheet-fed offset press

and perfecting sheet-fed offset press.

SINGLE- COLOUR SHEET-FED PRESS

This press is designed to print a single colour on one side of a sheet at a time.

MULTICOLOUR SHEET-FED OFFSET PRESS

This press allows more than one colour to be printed on one side of a sheet during printing. This press

has more than one printing unit.

PERFECTING SHEET-FED OFFSET PRESS

This press has the ability to print on both sides of the sheet during printing operation.

Page 21: Sheet fed offset press operating: Importance  of Strategic Operation Management

21

Porter (1993: 2) poses the following questions:

‘We need to ask ourselves what exactly our company is. What are its functions and how does it

currently operate? Finally, how can it be controlled to allow progression? Only when these questions

are properly answered will it be possible to concentrate on examining and assessing operating and other

problems and the possibilities that exist to improve the management of the situation.’

Management functions include five basic activities: Planning, Organizing, Motivating, Staffing and

Controlling (David: 2009). This study will investigate how strategic planning can assess and examine

operating problems on a sheet-fed offset press as well as how strategic management decisions are

formulated, implemented and evaluated to manage these problems.

2.8 INKING UNIT According to Kipphan, ´a thin film of ink is transferred from the image areas of the plate to the

substrate (ink film thickness on the substrate around 1µm).The inking unit’s function is to provide a

constant supply of fresh ink to the image areas on the plate to maintain a constant inking process`

(Kipphan, 2001, p.213). The Graphic Arts Technical Foundation (2001: 41) identifies four basic

functions of inking system.

They are:

(1) It moves the ink from the ink fountain to the plate

(2) It breaks down the thick charge of ink into a thin, uniform film around the rollers

(3) It works the ink into a printing solution

(4) It removes image repeats on the form from previous printing cycles.

The inking system consists of the following parts:

(a) Ink fountain

(b) Ductor or ductor roller

(c) Oscillators or Vibrators

(d) Intermediate rollers

(e) Form rollers

The ink is transferred from the ink fountain via the rollers on to the image areas on the plate. Kipphan

states that ´there must be an equal balance between ink fed and ink dispensed in order to avoid

variations in the ink density on the printed image` and adds that ´another important factor for the

Page 22: Sheet fed offset press operating: Importance  of Strategic Operation Management

22

print quality is the uniformity of the ink film thickness on the image areas of the plate or the image

areas of the substrate` (Kipphan, 2001, p. 213).

The flow of ink and ink consistency are essential during press operation to achieve efficiency,

effectiveness and productivity. Dejidas and Destree state that ´depositing, a metered, exacting film of

ink on the printing plate is essential to quality printing` (Dejidas and Destree, 2005, p. 227). On the

other hand, inconsistency of ink and poor flow of ink during press operation has a negative effect on

the colour and mars the print quality.

2.9 DAMPENING UNIT The offset lithographic plate is designed to make the image areas ink receptive and non-images water

receptive. According to Dejidas and Destree, ´the wet dampening film applied by the dampening

system serves to repel ink from the nonimage areas of the plate` (Dejidas and Destree, 2005, p. 313).

According to the printwiki website, ́ the dampening system of an offset press keeps non-image

areas of the plate moistened so that they will repel ink.

The non-image areas of a plate have been desensitized during platemaking to facilitate

water receptivity. An offset press dampening solution, commonly referred to as a fountain

solution, can consist entirely of water. As this is generally ineffective for long print runs,

synthetic desensitizers are added to the fountain solution to maximize the ink repellency

of the non-image areas of the plate.` Shafer and Meredith state that ´managing and

running a production system efficiently and effectively is at the heart of the operations

activities` (Shafer and Meredith, 1998, p. 7).

Kipphan notes that ´dampening units have developed from the “dampening roller” used to dampen

the lithographic stone. Vibrator-type dampening systems and continuous flow dampening systems are

systems with contact between the dampening solution pan, the dampening vibrator, and the printing

plate. ̀ He also adds that ́ the disadvantage of these dampening systems lies in the fact that substances

(e.g., particles of ink, paper dust) can get from the printing plate into the dampening solution pan and

can lead to contamination` (Kipphan, 2001, p. 218). If the dampening system and the solutions are

effectively controlled on the press, most especially during initial make ready operations, machine

down time would be reduced, which, in turn, improves the print quality, efficiency and effectiveness

of press operations.

2.10 DELIVERY UNIT According to Kipphan, ´a straight-edge delivery pile is usually required, where each of the delivered

sheets is jogged one by one to produce a neat pile. The deliveries of sheet-fed offset presses are

equipped with sheet joggers, which take every sheet to the same position on the pile. Exact pile

formation is essential to avoid a manual or automated sheet alignment before subsequent finishing

Page 23: Sheet fed offset press operating: Importance  of Strategic Operation Management

23

operations can be performed` (Kipphan, 2001, p. 247). Shafer and Meredith note that ´operations is

the part of the organization concerned with transforming inputs into outputs` (Shafer and Meredith,

1998, p. 16).

Blank sheets of paper are fed on to the sheet-fed offset, either by a successive or stream feeding

system via a feeding unit as input and are delivered as printed sheets of paper during press operation

to the (output) delivery unit. According to Dejidas and Destree, ´the most common types of delivery

systems found on sheet-fed presses are the chute delivery and the chain delivery. With the chute

delivery, paper is delivered to a receiving tray that must be emptied frequently. ̀ They continue, ´trays

may include jogging mechanisms that stack the sheet neatly on chain delivering tray. With the chain

delivery paper is delivered by gripper bars revolving on chains to a table that automatically lowers,

allowing sheets to be stacked` (Dejidas and Destree, 2005, p. 129). The chute delivery is meant for

small duplicator sheet-fed presses and the chain delivery is designed for high-speed sheet-fed offset

presses. The constant flow of sheet of paper (substrate) during press operation enhances productivity.

2.1.1 PRINT QUALITY Quality printing jobs depend on the work activities in the prepress, the actual printing process (press)

and the press techniques as well as the material (ink and paper) availability for production (Kipphan:

2001). Quality is frequently used to indicate the ´excellence` of a product or service (Oakland: 1989).

According to Dale, ́ there are a number of ways or senses in which quality may be defined, some being

broader than others but they all can be boiled down to either meeting requirements and specifications

or satisfying and delighting the customer`( Dale, 1999, p. 5). Kipphan (2001) identified the factors of

influence and specifications that determine the quality of print. They include:

INFLUENCES Prepress

(b) Colour separation

(c) Screening

(b) Mottling

Page 25: Sheet fed offset press operating: Importance  of Strategic Operation Management

25

(c) Evenness

2.1.2 QUALITY POLICY In today’s print market, customer requirement for quality product or service is high, so a company´s

quality policy can help management in satisfying its customers’ needs. According to Dale, ´customer

requirements for quality are becoming stricter and more numerous, and there are increasing levels of

intolerance of poor–quality goods and services and low levels of customer service care` (Dale, 1999,

p. 10). Business Dictionary.com defines quality policy as ´top management´s expression of its

intentions, directions, and aims regarding quality of its products and processes` (2015)

However, customers may have totally different thoughts about print quality. So print quality policy

should be tailored in conformity with the customers’ specification or requirement. Porter asserts that,

´quality control should not be the responsibility of one final inspecting department. It must be the

concern of all the production staff at each stage of production if work is to be consistently produced

to the required standard to meet agreed specifications` (Porter, 1994, p. 198). He further adds that

´management should adopt a positive attitude to quality and develop high standard and effective

communication` (Ibid: 199). Therefore, a company´s quality policy gives the staff a focus and direction

on what to do, how to do it, when to do it and the standard.

2.1.3 SIX SIGMA Bill Smith, a senior engineer, presented the concept of Six Sigma to Motorola in 1986. As part of a

business strategy, the objective was to identify and remove defects from business operations. Six

Sigma was applied across the system to enhance manufacturing processes for improved product

quality and client satisfaction. Truscott (2003) (cited in Henderson, 2006, p. 3). states that ´Six Sigma

focuses on establishing world-class business-performance benchmarks and on providing an

organizational structure and road-map by which these can be realized.

D is the define phase in which the customer´s needs and project goals are defined and considered

during the implementation of Six Sigma for process improvement projects and new product

development projects.

M is the measure phase for measuring the market needs, collecting relevant data and examining the

current processes for a new product or service.

A is the analyse phase in which data are investigated, and cause and effect are verified prior to the

production process.

Page 26: Sheet fed offset press operating: Importance  of Strategic Operation Management

26

I is the improvement phase, which ensures the current process or data collection and analysis by using

techniques such as mistake proofing, design experiment and standard work to create a new, feature

state processes.

C is the control phase, which ensures that any deviations from the target are corrected before they

result in defects. Quality control systems such as statistical process controls are put in place.

According to Harmon, ´projects begin with problems. The challenge is to figure out the nature of the

problem, and then to consider what kind of intervention might be required to resolve the problem`

(Harmon, 2007, p. 203). The application of the Six Sigma roadmap in this work in defining, measuring

and examining the sheet-fed operational problems, causes and remedies would help to boost the

efficiency, effectiveness, production and quality management in the printing organisation.

2.1.4 HIDDEN FACTORY

Business Dictionary.com (2015) defines Hidden Factory as ´activities that reduce

the quality or efficiency of a manufacturing operation or business process, but are not initially known

to managers or others seeking to improve the process. Six Sigma initiatives focus on identifying

"hidden factory" activities in order to eliminate sources of waste and error`.

2.1.5 14 DEMING POINTS W. Edwards Deming offered 14 key principles for management to follow for significantly improving

the effectiveness, efficiency and productivity of a business or organisation. Many of the principles are

philosophical and others are more programmatic. The details were first presented in his book, ´´Out

of the Crisis``. The 14 points are extracted from Deming.org

1. Create constancy of purpose toward improvement of product and service, with the aim to become

competitive and to stay in business, and to provide jobs.

2. Adopt the new philosophy. We are in a new economic age. Western management must awaken

to the challenge, must learn their responsibilities, and take on leadership for change.

3. Cease dependence on inspection to achieve quality. Eliminate the need for inspection on a mass

basis by building quality into the product in the first place.

4. End the practice of awarding business on the basis of price tag. Instead, minimize total cost. Move

toward a single supplier for any one item, on a long-term relationship of loyalty and trust.

Page 27: Sheet fed offset press operating: Importance  of Strategic Operation Management

27

5. Improve constantly and forever the system of production and service, to improve quality and

productivity, and thus constantly decrease costs.

6. Institute training on the job.

7. Institute leadership (see Point 12 and Ch. 8). The aim of supervision should be to help people and

machines and gadgets to do a better job. Supervision of management is in need of overhaul, as

well as supervision of production workers.

8. Drive out fear, so that everyone may work effectively for the company (see Ch. 3).

9. Break down barriers between departments. People in research, design, sales, and production

must work as a team, to foresee problems of production and in use that may be encountered with

the product or service.

10. Eliminate slogans, exhortations, and targets for the work force asking for zero defects and new

levels of productivity. Such exhortations only create adversarial relationships, as the bulk of the

causes of low quality and low productivity belong to the system and thus lie beyond the power of

the work force.

Eliminate work standards (quotas) on the factory floor. Substitute leadership.

Eliminate management by objective. Eliminate management by numbers, numerical goals.

Substitute leadership.

11. Remove barriers that rob the hourly worker of his right to pride of workmanship. The responsibility

of supervisors must be changed from sheer numbers to quality.

12. Remove barriers that rob people in management and in engineering of their right to pride of

workmanship. This means, inter alia, abolishment of the annual or merit rating and of

management by objective (see Ch. 3).

13. Institute a vigorous program of education and self-improvement.

14. Put everybody in the company to work to accomplish the transformation. The transformation is

everybody's job.

The relevancy of these 14 points today is examined to show how printing variables during make- ready

reduce downtime and increase efficiency, effectiveness, productivity and profitability.

2.1.6 MAKE-READY Make-ready refers to the processes that are used to organise the sheet-fed offset press to print a

particular work. It covers all the activities the press operator performs between starting the job and

running of the job on the press (Hird: 2000). According to Dietz, ´make-ready in printing is the process

Page 28: Sheet fed offset press operating: Importance  of Strategic Operation Management

28

of building up type and illustrative plates by means of overlays to obtain a balanced impression (Dietz,

1942: 393).

Make-ready has to do with the preparation of the press for printing operation. Faux asserts that ´it

begins when the last printed job is completed and the press is set up for the new production job which

follows` (Faux, 1983:76). Faux identifies the essential steps, traditional printing, to good make-ready

as:

a) Check the work instruction

b) Prepare the pile

c) Feeder setting

d) Feedboard setting

e) Set the sheet path

f) Delivery setting

g) Fitting the plate

h) Preparing the dampers

i) Ink preparation

j) Wash off plate

k) Printing

l) Setting register controls

m) Obtaining the pass sheet and running on

n) Wash up

To carry out make-ready for print operation, according to Kipphan, ´After completion of the various

cleaning processes, presetting the units for paper and ink feed as well as changing plates, the final

step in the preparation of the press for the next print job can take place, that is, fine adjustment during

paper travel.` For an automated press, he adds, ´Like the preparatory operations prior to paper travel,

this can be done straightforwardly, simply, and quickly from a central control console` (Kipphan, 2001:

329). In automated press, the printing variables and operations are monitored and adjusted from a

digitally controlled console.

2.1.7 PRINT OPERATIONS MANAGEMENT According to Heizer and Render, ´operations management (OM) is the set of activities that creates

value in the form of goods and services by transforming inputs into outputs´ (Heizer and Render

2004:4). An operating system is a ´configuration of resources` put together for the provision of goods

or services (Wild, 1995). The person in charge of print operations is known as the operations or

production manager, as the case may be, so he or she is concerned with physical resources (inputs),

machines (presses) and labour (operators).

Page 29: Sheet fed offset press operating: Importance  of Strategic Operation Management

29

Heizer and Render remind us that, ́ all good managers perform the basic functions of the management

process` and that the ´management process consists of planning, organizing, staffing, leading, and

controlling. Operations managers apply this management process to the decisions they make in the

OM function` (Heizer and Render, 2004:6).

So, it is important to check all the printing variables before the press is run and the operator´s manual

should be well understood, and, according to Krajewski and Ritzman, ´operations management is

crucial to each type of organization because only through successful management of people, capital,

and materials can an organization meet its goals.’ They further add that ´today, the term operations

management refers to the systematic direction and control of the processes that transform inputs into

finished goods and services` (Krajewski and Ritzman, 1993:3).

Hird notes that, ´a standard procedure of starting a press should always be followed. In this way, you

will find that a minimum of time will be consumed in setting up press` (Hird, 2000:498). This reduces

production time and machine downtime, and increases efficiency, effectiveness and productivity.

2.1.8 EFFICIENCY Dictionary.com (2015) defines efficiency as ´the state or quality of being efficient, or able to

accomplish something with the least waste of time and effort; competency in performance. It notes

that, ´accomplishment of or ability to accomplish a job with a minimum expenditure of time and

effort`. This means the extent to which time, effort, or cost is well-utilised for the designated project or

operation; thus, efficient performance of printing variables will boost the press operation.

2.1.9 EFFECTIVENESS Businessdictionary.com (2015) defines effectiveness as ´the degree to which objectives are achieved

and the extent to which targeted problems are solved. In contrast to efficiency, effectiveness is

determined without reference to costs and, whereas efficiency means “doing the thing right”,

effectiveness means “doing the right thing”`.

2.1.10 PRODUCTIVITY Investopedia.com (2015) defines productivity as ´an economic measure of output per unit of input.

Inputs include labor and capital, while output is typically measured in revenues and other GDP

components such as business inventories. Productivity measures may be examined collectively (across

the whole economy) or viewed industry by industry to examine trends in labor growth, wage levels

and technological improvement`.

Page 30: Sheet fed offset press operating: Importance  of Strategic Operation Management

30

Porter notes that ´printing companies are fast becoming aware that the cost of work to the client is

not the criterion by which the company will be judged` (Porter, 1994:197), but they would be

considered for patronage when they could produce good print quality, prompt delivery and cost

leadership. Faux stresses that ´the standard of quality for the job is set when the pass sheet is

obtained. This establishes the image position, register, image quality, ink density and half tone

reproduction quality` (Faux, 1983:99).

2.2.1 PRESS AUTOMATION Modern printing presses are equipped with automatic integrated systems, which have improved press

performance, reduced wastage, increased speed and also reduced power consumption. In a conventional

press, the feeding, delivery, registration, plate and other mechanical and electrical parts were all

adjusted and controlled manually by the operator. Kipphan asserts that `the printing industry as a whole

has generally been undergoing enormous structural and technological change for several years`. He

adds that ̀ increasing automation of all the steps in the process of printing house will create an enormous

potential for innovation in the field of machinery and equipment but also in processing in the coming

years` (Kipphan, 2001:10). According to Groover “the use of automated equipment compensates for

the labor cost disadvantage relative to international competitors. Automation reduces labor costs,

decreases production cycle times, and increases product quality and consistency“(Groove, 2008 p.3).

LEVEL OF AUTOMATION. Groover (2008) identified the level of automation as: semi-automation and total automation.

SEMI-AUTOMATION A semi-automated machine executes a part of the work phase with a controlled system in conjunction

with the operating system, and human effort is required for the other part of the work phase during

the machine operation for efficiency, effectiveness and productivity.

FULL AUTOMATION A fully automated system is when the whole machine or equipment system is a motorised integrated

system. The automated equipment works with no human attention, but the automatic processes may

be monitored on the computer system or the control console. Groover claims that “a worker is not

required to be present during each cycle. Instead, the worker may need to attend to the machine

every tenth cycle or every hundredth cycle” (Groover, 2008, p.6).

According to the Siemens website on automation of printing press applications “the printing

marketplace with printing systems and auxiliary equipment,… press automation, drive and motor

packages. These integrated systems result in higher speed, improved performance, lower power

consumption and less waste” (Siemens, 2015). With press automation, printing machine efficiency,

strength and productivity are improved.

Page 31: Sheet fed offset press operating: Importance  of Strategic Operation Management

31

The automation and digitalization of press operations have reduced machine downtime, increasing

efficiency, effectiveness and productivity while print quality and customer satisfaction have also been

improved. With press automation, printing operations are monitored on a control console and the plates

are fixed and removed (automated plate mounting) on the press automatically. The presses also have an

inbuilt colour control system that controls the inking and registration on the press.

According to Dejidas and Destree (2005), the process of fixing and removing the plate automatically

(automated plate mounting) is as follows:

(a) New plates are loaded into a plate cassette by the press operator

(b) The unit that needs the new plates is selected and the push button is depressed to begin the mounting

(c) The safety guards open automatically and the plate loader moves towards the plate unit

(d) The plate clamp is opened and the old plate is removed and kept in the loader automatically

(e) The new plate is moved from the loader and positioned for automatic plate mounting on the plate

cylinder

(f) The plate clamp is closed, returned to its original position and, finally, the safety guard is closed.

Automated press operations have the following advantages over conventional press operations:

(a) Ink consistency

(b) High quality

(c) Greater productivity

(d) Reduce machine downtime

(e) Reduce production time

(f) Save operational costs

CHAPTER THREE

METHODOLOGY

QUANTITATIVE RESEARCH DESIGN

3.1 INTRODUCTION Quantitative research method was used for this study, and, according to Creswell, ‘A survey design

provides a quantitative or numeric description of trends, attitudes or opinions of a population by

studying a sample of that population’ (Creswel, 2009:145). May (2011) stresses that a self-completion

questionnaire offers ‘a relatively cheap method of data collection over personal interview’ (May, 2011:

103). As a result of this assertion, the author has chosen a self-completion questionnaire to carry out

the study. A self-completion questionnaire was designed through surveymonkey.com and also

manually distributed to printing companies to complement the online respondents.

The self-completion questionnaire was well-structured and designed with the assistance of my

supervisor.

Research question

The research question examines areas as yet unclarified in the reasons for the research.

The research question is:

Can controlling printing variables during make- ready reduce downtime and increase efficiency,

effectiveness, productivity and profitability?

3.2 RESEACH OBJECTIVES The research objectives were based on Six Sigma- DMAIC Roadmap.

To define the printability and quality of a print job on sheet-fed offset

To measure, collect data and examine the printing process on a sheet-fed offset press

To analyse the collected data, and the causes and effects of a good quality print job

To improve on a quality printing job

To control and sustain the standard of a quality printing job

3.3 SCIENTIFIC METHOD IN RESEARCH DESIGN Scientific method is the study which forms the basis of advanced scientific research. It is, therefore,

important to raise some of the main assumptions in this method of enquiry, and to identify some of

its major features (Walliman: 2005). Domegan and Fleming note that “an overall framework for the

Page 33: Sheet fed offset press operating: Importance  of Strategic Operation Management

33

research process to facilitate later decisions that need to be made. It can be exploratory, descriptive

or casual” (Domegan and Fleming, 2007: 24).

Walliman states that “Research is a term loosely used in everyday speech to describe a multitude of

activities, such as collecting masses of information, delving into esoteric theories and producing

wonderful new products” (Walliman, 2005: 8).

This study is exploratory in nature and meant to discover a new way to improve on print quality and

customer satisfaction. May (2011) claims:

“The planning of a social survey requires attention to both the research design and the method of data

collection. Virtually all surveys aim to describe or explain the characteristics or opinions of a

population through the use of a representative sample” (May, 2011: 94).

3.4 QUALITATIVE RESEARCH Domegan and Fleming define qualitative research study as “the collection of data which is open to

interpretation, for instance on attitudes and opinions, and which not be validated statistically”

(Domegan and Fleming, 2007: 158). Malhotra argues that qualitative research methods can be defined

as “an unstructured, exploratory research methodology based on small samples, which provides

insight and understanding of the problem setting” (Malhotra, 2010: 171).

Berg and Lune attempt to differentiate between the qualitative and quantitative approaches, noting

that “qualitative research, thus, refers to the meanings, concepts, definitions, characteristics,

metaphors, symbols, and descriptions of things. In contrast, quantitative research refers to counts and

measures of things, the extents and distributions of our subject matter” (Berg and Lune, 2012: 2).

3.5 QUANTITATIVE RESEARCH According to Bordens and Abbott, “a quantitative theory defines the relationships between its

variables and constants in a set of mathematical formulas. Given specific numerical inputs, the

quantitative theory generates specific numerical outputs” (Bordens and Abbott, 2011: 38). Malhotra

argues that quantitative research is “a research methodology that seeks to quantify the data and,

typically, applies some form of statistical analysis” (Malhotra, 2010: 171).

The author has chosen this method, so that a statistical analysis can be used for the data, findings and

results. Almost all surveys aim to ´describe or explain the characteristics` or views of the population

through the utilisation of a representative sample (May, 2011)

Page 34: Sheet fed offset press operating: Importance  of Strategic Operation Management

34

3.6 DATA SELECTION

The design selected must indicate ‘the selection process for individuals’ (Creswell, 2009). Thus, a

random sample was chosen. The study considered printing companies that have sheet-fed offset

presses. However, the approach of a qualitative method to investigate data selection and collection is

different, ‘although the processes are similar’ (Ibid). The selection process for the participants was

random, and the study focus was in Dublin and its environs. Creswell (Ibid: 148) stresses the need to

“indicate the number of people in the sample and the procedures used to compute this number.”

May (2011) argues that “The self-completed questionnaire sequence is relatively better to be arranged

social-psychologically rather than logically”. The questionnaire was well-structured, and

surveymonkey.com platform and its tools were used to arrange the questions with the help of my

supervisor. Brook asserts that ”the most effective method of documenting an improvement project is

through use of a project working file that is written as a presentation, kept updated as a presentation,

and structured clearly around DMAIC phases” (Brook, 2006: 27). This study explored the DMAIC

roadmap to define, measure, analyse, improve and control the print quality and productivity on offset

sheet operating systems.

3.7 DATA COLLECTION The population sample were fifteen (15) printing companies and the author considered reliability and

standard in choosing these printing companies, although, the responses remained anonymous for

privacy and security reasons in this research work.

The author, with the assistance of the supervisor, considered the following eleven factors when

designing the self- questionnaire, as indicated by May (2011).

a) The questions should not be too general: the questions were grouped into two categories: (1)

Operation and (2) Management. They were all printing operation and management-related.

b) The simplest language should be used: the words and terms used were simple and easy to

understand.

c) Prejudicial language should be avoided: biased words, languages or terms were avoided.

d) Vague words should be eliminated: all the words used were clearly understood.

e) Leading questions should be avoided: leading questions were not given or used when

designing the questions.

f) The participants should not be caught unawares: enough time was given to the respondents

to answer the questions.

g) The questions should be open: hidden questions were avoided.

Page 35: Sheet fed offset press operating: Importance  of Strategic Operation Management

35

h) Hypothetical questions should be avoided: the questions were straightforward, easy and

direct.

i) The researcher should not include any personal questions in the questionnaire: all the

questions were related to sheet-fed offset printing operation, but not personal.

j) The researcher should build questions that would lead to problem-solution analysis: the

questions were set to test the research question.

The study ran for almost two months on surveymonkey.com platform (online). However, due to low

online response, the author then printed out the questionnaire, bound them together, and manually

passed around then to random respondents.

3.8 OBSERVATION The author has chosen observation method to complement the self-questionnaire in order to gather

additional data for this study. Walliman explains that “Observation is a method of recording

conditions, events and activities through the non-inquisitorial involvement of the researcher”

(Walliman, 2011:195). The author intended to use this method to evaluate and analyse the

operational procedures of sheet-fed offset press. Creswell states that “researchers collect data on an

instrument or test (e.g., a set of questions about attitudes towards self-esteem) or gather information

on a behavioral checklist (e.g., where researchers observe a worker engaged in using a complex skill”

(Creswell, 2009:15).

3.9 PRIMARY RESEARCH There are various methods of conducting primary research methodology, including qualitative,

quantitative and mixed methods approaches. Therefore, the choice requires selected which design

can be best utilised to examine a subject (Creswell: 2009). According to Smith, Todd and Waldman,

“the first stage in quantitative data analysis is getting your data into a format that you can analyse”

(Smith, Todd and Waldman, 2009:97).

For this study, quantitative research methodology was used as the primary research method so that

the data selection and collection could be analysed and interpreted by using tables, charts and

statistical methods.

3.10 SECONDARY RESEARCH

All research studies demand secondary sources for the background to the subject. The researcher will

necessarily need to identify what the context of his or her research inquiry/problem is, and he or she

will equally get an approximation of the current theories and thoughts (Walliman: 2011). According

to O’Leary, “The production of new knowledge is fundamentally dependent on past knowledge”

(O´Leary, 2004:66). Walliman describes the advantages of using secondary research as “they have

Page 36: Sheet fed offset press operating: Importance  of Strategic Operation Management

36

been produced by teams of expert researchers, often with large budgets and extensive resources way

beyond the means of a single student”(Walliman, 2011: 177).

According to Bryman, “secondary analysis is the analysis of data by researchers who will probably not

have been involved in the collection of those data, for purposes that in all likelihood were not

envisaged by those responsible for the data collection” (Bryman, 2012:312). The secondary data used

in this study, as shown in the literature review, made reference to books, paper articles, academic

journals and any other relevant newspapers or online sources. The author engaged in the secondary

research study in advance, so this afforded an in-depth knowledge of the topic before carrying out the

survey.

3.1.1 DATA ANALYSIS When data are collected using the self-completion questionnaire, it is of paramount importance to

analyse them (May, 2011). Creswell (2009) recommends the following research plan: a table with

numbers and percentages showing the respondents and non-respondents and vital information about

data selection, collection and analysis.

a) The researcher should explore the ‘response bias’.

b) The researcher should discuss the overall plan to give a descriptive analysis of data for

independent and dependent variables.

c) The researcher should indicate the ‘statistics for testing the hypothesis’ (Creswell

d) 2009).

e) The researcher should maintain reliability and consistency by showing the statistical procedure.

f) The researcher should produce the results in tables or figures and interpret the results from the

statistical test.

The recommended research plans were put into consideration during the discussion and data analysis.

May (2011) stressed that ‘The initial phase will involve describing the sample survey data using tables,

graphs and descriptive statistics’ (May, 2011: 122). The author analysed and interpreted the data using

tables, charts and statistical methods. This study used the questionnaire response to collect and

analyse data so that the research question could be tested.

3.1.2 RELIABILITY AND VALIDITY The author ensured that the research study was reliable and consistent, and ambiguous questions

were avoided for the purposes of clarity. The results were illustrated through use of tables and figures.

Page 37: Sheet fed offset press operating: Importance  of Strategic Operation Management

37

3.1.3 LIMITATIONS

Time constraints, the semester allowed less time than may be ideal for a quantitative design study,

and the low response of respondents via surveymonkey.com prevented the author from obtaining

more than fifteen (15) respondents. There were 9 respondents from surveymonkey.com, while the

remaining six respondents submitted their data through hard copy, i.e. face-to-face. As a student,

economic reasons also prevented the researcher from going beyond this scope.

3.1.4 DELIMITATIONS

The researcher chose DIT Press as the place to carry out the practical observations; however, DIT’s

sheet-fed presses were under repair at the time of this study and, therefore, press observation was

not carried out. In addition, the author was not allowed to carry out press observation for the study

in other printing companies because of staff restrictions in the printing companies in Ireland.

CHAPTER FOUR

4.1 INTRODUCTION A survey on `Sheet-fed Offset Press Operating: the Importance Of Strategic Operation Management

was conducted from March 11th to May 10th. Respondents were sampled using the Survey Monkey

platform and a hard copy was distributed manually to boost the total number of respondents. A

detailed overview of the survey methodology has been described in chapter two. The survey

questionnaire was divided into two categories. The first was for the Sheet-fed offset press operator

(15 questions) and the other for the management (13 questions). This study was intended to examine

the operation of a sheet-fed offset press, the problems and their causes and the strategic

management required to prevent operating problems or to provide possible solutions

4.2 MAKE- READY EFFICIENCY/EFFECTIVENESS SURVEY

4.3 PRESENTATION OF SURVEY RESPONSES: MANAGEMENT AND OPERATOR

Question 1

Do you have a strategic operational plan established?

The respondents were asked about strategic plans in their organisations, of which 67% answered YES

while 33% respondents said No. This shows that most of the sheet-fed offset presses put in place a

strategic operational guideline to prevent and correct any print defects that could affect the print

quality.

In quality management, 77.78, which is approximately 78% of the respondents, agreed that a quality

management system was available in their firms while 22% said one was not available.

Question 3

Do you have a standard operating procedure for press operations, including-make ready?

Figure 3 (4.3.3)

The respondents were asked if a standard operating procedure for press operation was included in

the make-ready. The majority of the respondent (78%) answered YES, while the remaining 22%

respondents said NO.

Question 4

How do you benchmark make-ready time?

Six respondents specified how they benchmark make-ready in their organisations. Some of the

respondents indicated that it was done manually and that it depends on availability of jobs,

requirements, processes and sizes, whereas another group said it depended on the press

manufacturer’s manual and the last group benchmarked through the control system with the aid of

automatic units. Thus, the settings were achieved and recorded for future make-ready lists.

Question 5

What impacts on planned make-ready time?

Out of nine respondents, only five showed interest in this question. According to those, the impacts

on planned make-ready time dependent on job’s availability, quality of substrate, colour issues,

mechanical or operator issues. Other factors were substandard material delivery, files availability and

queries at the prepress and press stages.

Question 6

Do you have a preventive maintenance policy for your printing equipment?

Figure 4 (4.3.4)

The respondents were asked whether they had a preventive maintenance policy for the sheet-fed

offset presses. Interestingly, all the respondents chose YES, not including those that did not participate

in the management part of the survey questions.

The respondents stated that the person in charge of preventive maintenance was either the

preventive manager, maintenance manager, maintenance officer, safety manager, or the press

operators.

Question 8

If no, how then do you look after your equipment?

There were no respondents for this question

Question 9

How much downtime (own plant) do you experience because of machine break down?

Five respondents indicated that it all depended on the age of the press, press condition, press run and

press maintenance, while the others skipped the question.

Question 10

What repair costs have you had in the last year?

Most of the respondents remained silent on this question, but two respondents gave a hypothetical

statement that they spent between 250 -10000 Euro annually

Question 11

How do you handle customers’ complaints?

Seven respondents indicated that customers’ complaints were received through feedback and others

skipped the question

Question 12

How many complaints have you received in the last year that related to print quality?

The majority received no customer complaints, while two respondents had received between two to

15 complaints within the last year as regards to print quality.

Question 13

Who approves conformance to standard at the make-ready stage of the job?

The approval of quality and standard at the make-ready stage in most of the printing organisations

depends on the organisational chart or hierarchy of each firm. All the respondents gave different

opinions to this particular question. According to the respondents, the approval is given by either the

production manager, management, operation manager, quality manager or supervisor.

CHAPTER FIVE

DISCUSSIONS AND ANALYSIS

5.1 INTRODUCTION The research objectives were based on the Six Sigma- DMAIC Roadmap

To define the printability and quality of a print job on sheet-fed offset

To measure, collect data and examine the printing process on a sheet-fed offset press

To analyse the collected data, and the causes and effects of a good quality print job

To improve on a quality printing job

To control and sustain the standard of a quality printing job

OBJECTIVE 1

To define the printability and quality of a print job on sheet-fed offset.

According to Slack, Chambers and Johnston, “the objective of good design, whether of products or

services, is to satisfy customers by meeting their actual or anticipated needs and expectations. This,

in turn enhances the competitiveness of the organization.” They further add that “using design, both

to generate new ideas and turn them into reality, allows businesses to set the pace in their markets

and even create new ones rather than simply responding to the competition” (Slack, Chambers and

Johnston, 2010: 114).

It is very important to put a quality management system in place; in other words, an offset printing

quality standards checklist is essential for any pressroom. The customer’s job should be well defined

according to the job specification or job ticket prior to the prepress and press operations. The quantity

of the paper, size of the job, required colour, plate and ink should be identified by an expert(s).

Waller claims that “a strategic plan is the detail of how an organization proposes to arrive at its desired

objectives” (Waller, 1999: 32). The printing variables need to be checked as planned or directed by

equipment suppliers and a standard operating procedure should be followed accordingly, because this

will enhance the make-ready and the press operations, which, in turn, improves the quality of print

output, increases customer satisfaction and gives the firm a competitive advantage over other firms

in the printing industry. Management should effectively communicate the strategic operational plan

to the staff and operators should be aware of all the pressroom variables that can affect the operations

and print quality.

Page 59: Sheet fed offset press operating: Importance  of Strategic Operation Management

59

5.3 OBJECTIVE 2

To measure, collect data and examine the printing process on a sheet-fed offset press.

In answering this research objective, poor print quality could be avoided when all the printing variables

are measured, data are collected and critically analysed before press operations. Brue argues that ‘Six

Sigma helps you identify the problems in your processes and reduce the defects that are costing you

time, money, opportunities, and customers’ (Brue, 2005, p. 1). The primary research has shown that

the impacts on planned make-ready time depend on job availability, colour issues, quality of the

substrate, files availability and customer demand. Preparation of the sheet fed-offset press is known

as ‘make-ready’. It starts when the final printed job has been done and the press is set up for the next

new production job (Faux, 1983).

The printing variables, such as work specification, pile, feeder, feed-board, sheet registration devices,

dampers, ink and other variables should be examined and accurately measured. The result for initial

make-ready shows that, for 46.67% of the respondents, two (2) initial make-readys was typically

common during a shift, and the recommended make-ready time for a specific/main Printing Machine

was between 6-10 minutes.

According to Stone, ‘an organisation’s success depends on it having the right people in the right jobs

at the right time, the organisation’s strategic business objectives and culture should determine the

people selected’ (Stone, 2010. p. 236). The author wanted to know if the machine operators were

technically qualified to measure and examine the printing processes during press operation. Thus, the

primary search shows that all the press minders were qualified to handle the print quality that will

satisfy customer needs as the result indicated that the operators have at least one the following

qualifications: National Craft Certificate, Senior Trades Certificate or National Vocational qualification,

and that they also received further training from the equipment suppliers.

Page 60: Sheet fed offset press operating: Importance  of Strategic Operation Management

60

5.4 OBJECTIVE 3

To analyse the collected data, and the causes and effects of a good quality print job.

According to Robbins, DeCenzo and Coulter, ‘planning involves defining the organization’s objectives

or goals, establishing an overall strategy for achieving those goals, and developing a comprehensive

hierarchy of plans to integrate and coordinate activities’ (Robbins, DeCenzo and Coulter, 2015, p. 145).

Participants in this survey indicated that the standard operating procedure was available in the press

houses and they were strictly abiding by it in relation to make-ready and that the policy could be

reviewed annually or whenever required, as the case may be. Faux stated that ‘any process

improvement should reduce variation, so we can consistently meet customer expectations’ (Faux,

2005, p. 6).

It is important to use job analysis for evaluation of print jobs right from the start through to the end

of the production. So, what is job analysis? According to Project People’s website, ‘Job analysis is a

systematic process for collecting and analysing information about jobs. Job analysis provides

information about the work performed and the work environment. It also identifies the knowledge,

skills, abilities and personal competencies people need to perform their work well’

(www.projectpeople.com, pdf file). The job description can be broken down into different categories

for further assessment; paper would be loaded and plates would be mounted on the press.

Primary search shows that benchmark make-ready time is set according to the available jobs, control

system or manufacturer’s manual. Therefore, correct setting of damping system, registration system

and ink control, as well as other printing variables, could prevent printing-related problems like

curling, picking, show-through, strike-through, creasing, poor drying, scumming, doubling and other

factors that could reduce print quality.

The research question has been tested and confirmed that controlling printing variables during make-

ready reduces downtime and increases efficiency, effectiveness, productivity and profitability. Thus,

as most of the respondents had received no complaints from their customers in the previous year for

poor quality job, this could be taken as meaning that adequate measures were taken to ensure that

all printing variables were well managed during and after operations.

Page 61: Sheet fed offset press operating: Importance  of Strategic Operation Management

61

5.5 OBJECTIVE 4

To improve on a quality printing job

In working to achieve and improve quality print jobs, Davis argues that ‘ an operations manager must

fully understand the company’s products or services, the process and process technologies used to

manufacture the products or provide the services, and the operating systems, methods and

techniques that govern the transformation process’ (Davis, 1998, p. 10). The survey shows that,

according to the respondents, conformance to standard at the make-ready stage at press houses was

done either by the production manager, operations manager, quality manager or supervisor.

These categories of people have the technical knowledge, skill and experience to maintain and sustain

the press quality standard as part of the strategic operational plan in any organisation. Dale, Wiele

and Iwaarden explain that ‘responsibility for quality service lies with operations, marketing, human

resources and other management- working together within an organization’ (Dale, Wiele and

Iwaarden, 2007, p. 234). The research study sampled both the operator and management in the survey

so that the research question could be viewed from both perspectives. The study shows that 77% of

the respondents had a quality management system to maintain and sustain the quality service

delivery.

The Six Sigma DMAIC roadmap provides adequate measure for any organisation to improve on a print

quality. Perry and Bacon stated that ‘The reality is that companies that do not proactively renew their

portfolios of products are likely to find themselves being acquired or simply out of business’ (Perry

and Bacon, 2006, p. 15). Therefore, Six Sigma techniques are used to collect customer requirement

data, identify customers’ needs and product data, design the production process, measure the

performance of the new product or service, and evaluate how well it matches up with the current

business environment.

Page 62: Sheet fed offset press operating: Importance  of Strategic Operation Management

62

5.6 OBJECTIVE 5

To control and sustain the standard of a quality printing job

The findings within this study have broadened the author’s knowledge, ideas and skills within the field

of operations, strategy and management areas. The control and sustainability of the standard of a

quality printing job can, perhaps, be achieved mainly on a project-by-project team basis, using a

workforce trained in performance-enhancement methodology`. Six Sigma uses several quality

management techniques, such as customer focus, leadership, involvement of people, decision-making

and statistical methods. This is aimed for the sustainability and quality control of print jobs, and

increases efficiency, effectiveness and productivity.

According to Perry and Bacon, `the roadmap that is almost universally accepted for operations of Six

Sigma projects is the tried-and-true DMAIC roadmap` (Perry and Bacon, 2006, p. 6). The Six Sigma

DMAIC (define, measure, analyse, improve, control) process is designed to identify and implement

process enhancements within the organisation. The author has found it relevant and useful for quality

evaluation, operational and job analysis. Given the survey’s result, this study has proved that strategic

operation management is important in sheet-fed offset press operation.

CHAPTER SIX

CONCLUSION AND RECOMMENDATIONS

6.1 CONCLUSION The research study showed the use of Six Sigma tools as good business strategy to evaluate and

examine sheet offset press problems, causes and remedies. The data selection, collection and analysis

were critically defined, measured, analysed, improved and controlled to prevent any deviation from

the original topic. Keller asserts that `a circle refers to a collection of data at a given experimental

condition. A circle is complete when one observation has been collected at each point in the design `

(Keller, 2011, p. 243). The researcher chose DIT Press for observation of this study, but at the time of

this study DIT Press was not in operation for one reason or another. Therefore, the author used his

over 20 years experience in the printing industry, along with the primary and secondary research, to

examine and evaluate the problems, causes and remedies on the sheet-fed press practically.

The author discovered, through primary and secondary research, that press automation and

innovative sheet-fed offset presses have improved the quality of print jobs and reduced downtime, as

well as press operations having been increased efficiently and effectively. Productivity, marketing and

sales have been improved as well, as a result of the rapid growth of technology.

This study is meant to serve as a reference point for students and printers, to help them provide

possible strategic management for major printing-related problems on a sheet-fed offset press. The

researcher believes that, if appropriate measures are put in place, the ink, dampen, paper, machine

and operational problems could be prevented.

Strategic management can be used to enhance print or product quality and customer satisfaction. It

can be used in problem-solving analysis, decision-making, internal marketing, and customer needs and

human resources management.

Page 64: Sheet fed offset press operating: Importance  of Strategic Operation Management

64

6.3 RECOMMENDATIONS

From the investigation and the testing of the research question, the research study will help to

enhance print quality. Therefore, the researcher recommends that:

a) Appropriate machine maintenance should be carried out on the presses regularly, according

to manufacturer specification

b) The manufacturer’s manual should be utilised

c) Speed limit of the presses should be maintained

d) A qualified press minder should man the press

e) Paper should be stored in an appropriate place at normal paper temperature

Furthermore, it is very important for any printer to keep abreast of the rapid growth of technology

and to review his or her operational strategy periodically, so that he or she can keep moving with the

times in order to remain a market leader and increase the barrier of entry to prevent new entrants

taking his or her market share and for gaining competitive advantage over others in the industry. The

research has proved that Six Sigma roadmap DMAIC is a relevant method that can be used in the print

and digital media industry, for both established and new entrant firms.

Requesting Participation in a Survey

Dear Sir,

In partial fulfilment of a BA (Hons) in Print and Digital Media Technology Management at

Dublin Institute of Technology, Ireland, I am conducting a follow-up survey on `Sheet-fed

Offset Press Operating: the Importance Of Strategic Operation Management` under the

supervision of Dr. Kevin Byrne, the head of department. As such, I would be very grateful for

your response to this survey as a valuable contribution to answering to the research question -

Can controlling printing variables during make-ready, reduce downtime and increase

efficiency, effectiveness, productivity and profitability?

This study is intended to examine the operation of a sheet-fed offset press, the problems and

their causes and the strategic management required to prevent operating problems or to provide

possible solutions. To which end, your experience in the printing industry could provide

extremely beneficial information. The questionnaire is divided into two categories. The first is

for the Sheet-fed offset press operator(s) and the other for the management

The self- questionnaires are attached as Doc files. Please feel free to include any additional

comments you deem necessary or relevant to the dissertation. Your response and time are

greatly appreciated. Thank you!

Sincerely

Abdulazeez Majek, Kareem
