Verifiers + Test Cards = Barcode Accuracy
Barcodes are required to be precisely printed, following a set of rigorous parameters, and unfortunately when they’re not, it may be impossible to detect problems with the naked eye. That’s where barcode verifiers come in. Although verifiers seem like every other scanner around, they actually perform very sophisticated tests on barcodes and report on the quality of the printed symbol. These machines (verifiers) must be kept maintained and calibrated to ensure the values they report are accurate.
New GS1 US Calibrated Conformance Test Cards Features
The test cards consist of a series of barcodes each intentionally printed with unique errors. If your verifier can spot them, your verifier can be trusted to function with accuracy. The 8 flawed barcodes are made up of:
- Quiet Zone infractions
- Defect symbols to reflect both 'voids' and 'spots'
- Decodability symbols to reflect both edge to similar edge bar flaws
- Low Modulation symbol to reflect loss of symmetry in reflectance through the symbol
- Low contrast symbol
