Across many industries, barcodes are intrinsically valuable to workflow. From pharmacies to farms, barcode labels play an integral role in supply chains and overall business performance through their unique ability to consistently and unobtrusively identify products.


New regulations, set to take effect in just over a year, will require that barcodes grade or verify more reliably. Previously, barcode reading was the basic standard, meaning that a barcode could be deciphered by the scanning device in use.


However, even “poor quality barcodes can be read under ideal conditions like excellent lighting,” and a clear reading under a particular set of circumstances does not offer assurance that a barcode can be reliably read in a dark warehouse or on a moving truck, for example.


Grading, also called barcode verifying, sets a quality and operability standard based off a letter ranking system using seven ranking factors:


  1. Decode – The ability of the barcode to be read. If decode fails, the overall barcode grade is a failure.
  2. Contrast – The difference between light and dark squares or dots in the barcode. Pure black and bright white provide the best contrast/highest grade.
  3. Modulation – Variation, or differences, in contrast throughout the barcode. Less variation is better.
  4. Fixed Pattern Damage – The quality of the squares/dots that form the perimeter of the barcode, plus the presence of the “quiet zone” surrounding the barcode.
  5. Grid Non-Uniformity – The barcode’s fit within specified horizontal and vertical boundaries.
  6. Axial Non-Uniformity – Alignment of the barcode with horizontal and vertical axes.
  7. Unused Error Correction – Amount of available Error Correction in a symbol, with 100-percent unused being the ideal case. Error Correction reconstructs data that is lost via damage, erasure of the symbol, or poor printing.”
