When printing Data Matrix barcodes onto folding boxes using inkjet or laser printing directly at the packaging line, achieving the required print quality can be challenging. An increased number of rejects and frequent machine stops will degrade overall packaging line efficiency. The barcode print quality is usually monitored by an in-line vision system, checking each printed barcode for the minimum mandated quality grade.

How to ensure that the in-line vision system is set-up correctly? How to ensure that errors are detected correctly to allow for  constructive root cause analysis?

Vesdo’s self-adhesive Compliance & Stress Barcode Labels will do just that. Simply apply to the item to be inspected and place in front of the in-line camera. Our Compliance & Stress Barcode Labels allow to selectively  trigger six different error channels for each quality grade ranging from A to F. The error channels are:

  • Contrast
  • Modulation
  • Fixed Pattern Damage (FPD)
  • Unused Error Correction (UEC)
  • Axial Non-Uniformity (ANU)
  • Grid Non-Uniformity (GNU)


The barcodes on Vesdo’s Compliance & Stress Labels comply with the relevant international standards:

  • ISO/IEC 15415
  • ISO/IEC 16022
  • ISO/IEC 15426-2
