Verification of barcode symbols
To ensure that the barcodes on your product labels can be read.
Barcode verification checks print quality, data structure and barcode dimensions, which have a direct impact on character readability and scan speed.
Verification is recommended at an early stage, even before the launch of a product on the market, and is a mandatory requirement of many business partners when starting business relationships, for example between retail chains and suppliers of goods.

The quality of the barcode depends on the color combination of the dash-light strip, compliance with the permissible dimensions, the printing technology and the packaging material. When the verification is done on packages that are not full, it should be taken into account that after they are filled, it is possible that this affects the contrast in the strokes or leads to a change in the shape of the barcode.
  • Traditional method
The traditional method considers two parameters: average size deviation and printing contrast.
  • ISO method (ISO/IEC 15416)
This method evaluates the quality of the symbol with a score ranging from 4 (highest) to 0 (lowest) based on how close the verified barcode is to the ideal.
Compared to the ISO method, the GS1 specifications specify minimum acceptable verification scores depending on the area of application of the barcode. For example, EAN-13 requires a minimum rating of 1.5 (C) when scanning a commercial cash register.
At the customer’s request, a technical report can be issued containing information on the performed inspection, evaluation of the quality of the barcode symbol and recommendations for improving the quality of printing, if applicable.
