With GS1 Sweden's Validoo barcode service you can check that your barcodes comply with GS1 standards so that they work when they are used.
Standards for barcode quality control
ISO/IEC 15416 is the globally applied procedure for checking the quality of barcodes. A number from 1 to 5 is used to grade the quality of the barcode. The method described in ISO/IEC 15416 is technically aligned with ANSI which GS1 Sweden uses for barcode quality control. The ANSI standard uses the letters A to F to grade the quality of the barcode. A to D are acceptable barcodes and F for those which fail.
GS1s standards require that barcodes shall have a quality of ANSI "Grade C" (corresponding to ISO/IEC 15416 "Grade 2") when the item reaches its best before date or, when no such date exists, at the time when the barcode will normally have ceased to be used in the supply chain.

GS1s template for barcode quality control
In both ISO/IEC 15416 and the ANSI standard there is a description of the parameters which are to be checked at barcode quality control. These parameters include checks that the barcode has the correct dimensions, that the contrast between light and dark bars is sufficiently high and that there are no defects to interfere with scanning.
When you check your barcodes with GS1 Sweden's Validoo Barcode service you will receive a report showing which parameters passed or failed according to GS1s standards. The report uses a template based on ISO/IEC 15416. The template has been developed by GS1 internationally in cooperation with other GS1 organisations and users of GS1 standards.
