Difference between barcode reading and barcode verification Barcode verification standards Ramifications of not having a barcode printing process in

control where bad barcodes might be printed


BARCODESAre the World’s Least Expensive and

Most Reliable Method of Recording Data


Verification

Verification is a method of analyzing a printed code against a published specification to determine whether the barcode is compliant to data structure specifications and will scan properly Microscan verifiers ensure

compliance and can also determine defects in printed codes that may affect readability.


Barcode Readers Compared to Barcode Verifiers

A barcode reader will: Recognize the barcode symbology Read the content of the barcode Transmit the data

A barcode reader will NOT: determine whether the barcode complies with

standards determine the quality “grade” of the barcode

A barcode verifier is a precision instrument used to determine barcode accuracy and quality


Verification Testing

Can you test a barcode with a scanner? No. Scanners cannot test the reflective and contrast properties of the barcode because they are positioned at a predictable distance and angle from the barcode. It is important to test reflectivity and contrast because it is an essential quality in any barcode, and if fails to meet minimum standards, accurate product identification is jeopardized. (Uncontrolled Set-up)

How do you test barcode quality and accuracy? Only with a verifier. Only a verifier will tell you when barcode quality is degrading during the printing operation, and help determine how to improve quality. With this tool, the printing process can be proactively corrected, providing protection against potentially damaging barcode errors. (Controlled Set-up)


Why is Verification Important?

Barcodes are predominantly used in the supply chain to identify and record the movement of goods (track and trace).

• Any barcodes that are not decodable in the supply chain can cause a breakdown in traceability and inefficiencies in the system.

Verification protects the benefits of using barcodes for automation.

• Speed, productivity, cost savings, and reduced errors.

Barcodes that comply with ISO standards are decodable using any scanner from manufacturer to customer.

• Even if a barcode reader can decode a symbol, it may contain flaws that do not pass the quality standards of the customer.


What about Validation?

If my printed barcodes are verified to an ISO print quality standards are they also validated? It depends on the

capabilities of the verifier.


Validation

Validation is the process of checking that the proper data has been encoded within a barcode.

• As an example, is data in the expected sequential order? Is it in the expected random order based on a database lookup (matchcode)?


Barcode Verification

Verification is an objective, precise standardized measurement of the quality of a barcode symbol. It is a predictor of how well a code will be able to be read throughout its life cycle.

Without verification, bad barcodes are not identified until they are unreadable. By the time a bad barcode is identified, several poor-quality barcodes may have already escaped down the line.

With verification, bad barcodes are prevented from being applied to the product, eliminating the chance for future failures.


Verification

• The verification test specifications are defined in the following globally accepted standards:

ISO/IEC 15415 and 15416 - Barcode print quality test specifications, as applicable.

ISO/IEC 15426-1 and ISO/IEC 15426-2 - Barcode verifier conformance specifications, as applicable.


Analyzing Your Print Quality

Microscan verifiers are designed easily and rapidly identify barcode problems, helping with resolve print quality issues to avoid product identification problems throughout the manufacturing and logistics supply chain

If defects are present, the verifier will locate and highlight the defect


Advantages of Verification

“High Quality” barcodes scan on the first attempt every time allowing end users to take full advantage of their scanning investment

• Higher productivity• 100% traceability• Fewer errors• Less operator frustration


Advantages of Verification

“High Quality” barcodes give you the assurance that your customers will be able to scan your barcodes on a broad variety of barcode scanners.

• Avoid customer fees• Avoid rejects• Limit returns and scrap


Risks of Not Verifying

• Lost or misinterpreted information

• Increased labor cost• High dollar re-labeling

costs• Increased errors• Product recalls• Rejected shipments• User dissatisfaction• Retail vendor compliance

penalties


Violation of compliance standards may result in fines known as “chargebacks.” Updating systems with verification

represents an up-front investment that will reduce costs in the long run, both from fees, and from time wasted identifying the cause of each chargeback. By far, the most common reason that

vendors incur chargebacks from their customers is barcode quality.

Off-Line vs. In-Line Verification Systems

In-Line Verification Off-Line Verification

100% label inspection, automated process Used for random sampling, manual process

Requires integration with label printing equipment or label “rewinder”

Sampling interval defined by the labeler, but typically at beginning and end of label production run

Not possible for direct part marking Off-line verifiers can inspect both labels and direct part marks

FDA does not mandate how labels should be inspectedOff-line inspection is an economical and easy way to begin an

label verification program Combination of off-line and in-line inspection is possible


LVS-95XX Series: Off-Line Verification Systems
