RD 8

SPGPrints’ most competitively-pricedprinting machine

The RD 8 is a system you can rely on. Specifically designed for long, reliable and highly productive use, it is ideal for

high-volume operations where quantity is a priority but quality has to remain high. It is completely compatible with the demands

of the modern printing process, allowing simple and rapid changeover to another design or colourway, straightforward

operation and excellent reproducibility.

The RD 8 is the successor to the well-established and extremely successful RD4, and is the latest in a long line of SPGPrints

machines that are well known for quality and reliability at an affordable price. Thousands of machines from this product family

are still in use worldwide today, testi mony to the durability, solidity, reliability and value they offer. The basic machine version has

a mechanical drive system.

Uniform and optimised glue application

The RD 8’s patented gluing system applies an extremely uniform layer of glue onto the printing blanket. It also helps reduce

glue consumption without compromising adhesion by making the location, width and thickness of the applied layer easy to set.

An optional thermoplast gluing device that consists of a glue application unit together with a cloth and a blanket heater is also

available.

Reliable operation

The robust, tried-and-tested mechanical drive system of the RD 8 provides long and uninterrupted service. A central main

motor drives both the printing blanket and screens. Based on this straightforward and reliable principle, literally thousands

of RD 4 printing machines - the predecessor of the RD 8 - have given years of productivity, with minimal interruptions for

maintenance. The RD 8 is also characterised by consistent performance even under demanding condi tions like tropical

tempera tures and high relative humidity.

Twin Drive

For those customers who are in favour of a variable lead setting the RD 8 Twin Drive is an attractive solution. In this execution

both the printing blanket and the drive of all the screen heads have their own motor, allowing for a flexible setting of the lead, a

fractional speed difference between printing blanket and screen head.

Accurate repeat setting

The longitudinal, lateral and diagonal repeats can be set at each printing position. The same applies to the squee gee pressure

and position and, when using roller squeegees, the magnetic flux. The repeat size is altered quickly and simply by changing

the screen bearings. Repeat sizes up to 1018 mm are possible.

Wide choice in infeed and discharge

A number of different infeed and discharge units are available for use with the RD 8 to expand your printing possibilities.

Customised solutions to meet any specific requirements you may have are also possible. Various dust removal systems

are available for use on the infeed side, to ensure that print quality is not compromised by contami nation through loose

particles.

COMBI position

The RD8 can be equipped with COMBI positions.

The unique COMBI position accommodates both blade squeegees and roller squeegees.

The COMBI position is equipped with a patented magnetic table based on permanent magnets.

The magnetic force is controlled electronically and set by means of a potentiometer.

Advantages of the blade squeegee are:

• Savingsondyestuff

• Pasteamount(left/right)controllableduringprinting

• Morepastedepositedonsurfaceresultinginvibrantcolours

• Welldefinedprint/outline

• Easycolor-matchduringstartup

Advantages of the patented SPGPrints roller squeegee are:

• Easytooperate

• Hardlyanydifferencebetweenadd-on,left-middle-right

The RD 8 accommodates two different squeegee systems - blade and roller - as well as combinations of both. The
