We understand that printing barcodes that cannot be scanned can be disastrous. PPL provides your organisation with a barcode verifying solution that ensures that your barcodes are 100% compliant.
Barcode verification works on the principle that it is better to scan, test, grade, highlight and fix errors with a barcode as they are printed.
Avoid compliance problem by using PPL to supply, install and maintain either the Printronix ODV-2, the Honeywell PX940 or the Toshiba TEC Scansure.
Our sales team is on hand to provide advice and support to those customers who are new to barcode verification solutions or to experienced buyers.

What is Barcode Verification?
Barcode verification grades the quality of barcodes according to established standards
Barcode verification is the process of grading barcodes. Barcode verifiers are precision instruments which enable the verification process. Barcode verifiers grade 1-D and 2-D barcodes according to quality parameters defined by industry standards which are developed by international organizations like ANSI/ISO and industry groups like GS1 and HIBCC. These standards enable interoperability between barcode printing and scanning systems, so that both industries and individuals can depend on symbols being printed and scanned successfully, regardless of where they were produced or handled.
Verification helps confirm that a code being produced will be accepted anywhere, by any reader. It is the only way to formally assign a grade to a barcode, as well as the most reliable way to diagnose and fix marking errors.
Benefits of Barcode Verification Printers
A barcode that does not scan correctly can cause serious problems, from manufacturing errors and production downtime to product returns and even fines. A failure to scan can be catastrophic, slowing down lines and causing costly reprints, wasted product, and chargebacks. Barcode verification allows anyone printing or marking codes to help prevent these issues and more.
The cost of reprinting and then reshipping corrected batches can be expensive. Verification can alert code producers to printing issues early in production. By monitoring verification results printers can pinpoint a code’s problem areas when quality starts to decline and take corrective action right away. Successful verification ensures that a label or direct part marker is working properly, and that codes will be readable throughout the supply chain. Verification reduces product returns, packaging waste, and other expenses.
Major retailers are known for issuing costly chargebacks and rejecting material that does not meet their standards for barcode readability. Rejected material is a serious expense that can cut into profitability and customer satisfaction. Barcodes that scan correctly don’t incur fines and avoid errors introduced by manual entry. For this reason, barcode verification has become an essential factor in supply chain management.
Contract and Industry Compliance
As well as helping to improve code quality, a verifier generates reports to certify the quality of a producer’s codes. This is why an increasing number of regulated industries require that manufactures use barcode verifiers. Reports can be printed or exported to a storage archive to prove compliance with contract and industry requirements. Most verification software will also check that the data within the barcode is formatted according to the application standard for a specific industry.
What do Barcode Verifiers Look For?
What is the code size range?
Consider the size of the narrowest bar or smallest module printed (normally expressed in mils, or .001 of an inch). To determine required camera resolution, look for a verifier with a minimum x-dimension that is smaller or equal to the smallest bar width or module. The total width of the largest barcode printed will determine the required field of view. A verifier’s field of view needs to be large enough to show the entire code including its quiet zone (space surrounding the outside of the code).
What are the codes printed on?
Codes appear differently to a barcode reader’s camera depending on the material they are printed on. To achieve proper illumination for some surfaces, specific lighting angles are required. Most verification standards for 1-D and 2-D codes specify 45° lighting for codes printed on labels. This ensures that some light reflects off of the label and goes back to the camera. For direct part marks (DPM) on a shiny, textured, or curved surfaces, a verifier with 30° and 90° or dome lighting option is necessary.
Are there oddly shaped parts?
Verifiers with adjustable height stands make it much easier to position codes on small, oddly shaped parts underneath the camera. When dealing with symbols on recessed areas of a part, a verifier’s software should be able to select specific regions and tell the camera exactly where to analyze a code.
What are the software features?
A barcode verifier’s software should be able to grade and diagnose issues within the barcode printing process. The right barcode verifier will generate reports that grade against relevant ISO and application standards.
Printronix ODV-2D Solution
The Printronix Auto ODV uses an external verifier attached to the outside of the best-selling Printronix T series barcode thermal label printer which scans, verifies and then records the quality of the barcodes against IISO/IEC and ANSI standards.
If the machine detects a faulty barcodes then customisable options include either to strike out the barcode or attempt to reprint it up to as many tries of your choosing. Will work for;
- Ladder Barcode
- 2D Barcodes
The advantage of using the Printronix ODV-2 verification system is that you can link it into your own software or use Printronix PrintNet Enterprise Software suite to capture details reports of every grade and barcode printed.
The Printronix T series printers are robust heavy-duty printers that are designed to cope in industrial environments where dirt and dust may cause issues. Connections include USB, Network and Wireless is available as an optional extra and can be used as a direct and indirect thermal transfer printer or simply and customers can choose whether to use a 203 / 300 DPI printheads.
If you already own a Printronix T-6000 or T-8000 series printer then the ODV system can be added retrospectively via an aftermarket field kit. Please contact our sales team for further information.

There are two main grading organisations. Our sales team can help you choose if you are unsure about which one you need to be compliant with. Some industries such as the military, pharmaceutical or packaging industries may even use their own barcode grading compliance systems.
ISO/IEC Verification Standards
Our verifiers are compliant with the appropriate standard which is ISO/IEC 15426-1 for linear barcodes and ISO/IEC 15426-2 for 2D verifiers. The part of the standard that measures barcode quality is ISO/IEC 15414 for linear barcodes and ISO/IEC 15415 for 2D barcodes.
The ANSI standards are ANSI X3.182-1990 and ISO 15416
ISO/IEC and ANSI use different recording standards. ISO/IEC records the barcode quality using a numeric system whereas ANSI gives them a letter grade. A comparison chart can be seen below:
|ISO/IEC Grade||3.5 – 4.0||2.5 – 3.5||1.5-2.5||0.5-1.5||0 – 0.5|
With a barcode verifier brought from Precision Peripherals you can set the machine to overstrike or reprint labels which score anything below an “acceptable” grade.
