Barcode verification for PDF files and print

BarProof builds quality into your process by taking it all the way upstream to your PDF files. BarProof automatically locates all barcodes on a label, carton or press sheet and grades each according to CEN/ANSI/ISO standards.  Bar width reduction (BWR) and magnification measurements are also provided. BarProof verifies and decodes 1D and 2D barcodes including UPC, Data Matrix and QR. The BarProof module is available as an option with ArtProof, ScanTVS.

BarProof is the only barcode decoder and verification tool for PDF files that provides grading, bar width reduction and magnification measurements, guaranteeing scannable barcodes at the checkout counter.



Bar width reduction


BWR is critical during the pre-press process in order to compensate for different packaging materials and ink spread during production. By verifying BWR values in PDF files upstream in the process, brand owners can be assured that barcodes will achieve expected quality levels



BarProof Benefits


  • Bar width reduction measurement
  • Barcode magnification measurement
  • Decode & grade 1D & 2D barcodes including Data Matrix, QR, MicroQR
  • Grade each barcode according to CEN/ANSI/ISO standards
  • Verifies and decodes linear 1D and 2D barcodes
  • Color coded  pass / fail reporting for barcodes
  • 21 CFR Part 11 / EMA Annex 11 compliant
  • Integrates with ScanTVS print inspection solution



Grading Criteria


Decode - Checks if the scan line data can pass the reference decode algorithm

Symbol Contrast - Checks the difference between the minimum and maximum reflectance of the scan line

Minimum Reflectance - Checks that the minimu m reflectance is less than half of the maximum reflectance

Minimum Edge Contrast - Checks the smallest edge contrast found in the scan line

Modulation - Checks the ratio of the minimum edge contrast to the symbol contrast

Defects - Checks for reflectance non-uniformity along the scan line

Decodability - Checks the accuracy of the barcode printing and image in relation to the appropriate symbology reference decode algorithm
