Ensuring Product Quality Through Comprehensive Print Inspection: Verification of Codes and Variable Data

Product labeling is subject to strict regulations in many countries. For consumers, it is essential that important information is clearly and legibly readable. Errors in labeling can have far-reaching consequences. Especially in the food and pharma sectors, comprehensive print inspection is now indispensable. Print inspection enables verification of various codes, including batch numbers, GTIN, EAN, barcodes and DMCs. It also allows inspection of variable data such as best-before dates, LOT and serial numbers, which is crucial for ensuring product quality.

  • ✔ Verification of product labeling
  • ✔ Quality inspection of logos, pictograms or symbols
  • ✔ Decoding and verification of 1D and 2D codes or Pharmacode
  • ✔ Inspection of variable data sets
