ISO/IEC 15415 standard

The ISO/IEC 15415 standard is primarily used to evaluate QR codes printed on labels.

The QR code is rated based on 8 different parameters. The rating process will evaluate decoding, character contrast, modulation, reflectivity,

The positioning pattern is damaged, axial non-uniformity, mesh non-uniformity, and unused error correction parameters are rated.

XTIOT provides 11 symbologies for Data Matrix ECC 200, QR Code, Micro QR Code or Aztec Code

Rating parameters: 'Overall Quality', 'Contrast', 'Modulation', 'Fixed Pattern Damage', 'Decode', 'Axial Non Uniformity', 'Grid Non-Uniformity', 'Unused Error Correction', 'Reflectance Margin' , 'Print Growth', and

'Contrast Uniformity'.

PDF417 symbology provides 7 rating parameters: 'Overall Quality', 'Start/Stop Pattern', 'Codeword Yield', 'Unused'

Error Correction', 'Modulation', 'Decodability', and 'Defects'.

ISO/IEC TR 29158 (AIM DPM-1-2006) standard

The AIM DPM-1-2006 standard is mainly used to evaluate the quality of QR code marking for direct part marking.

The quality parameters and rating process for DPM codes are similar to the ISO 15415 standard, but there are some important differences.

▪ Global threshold calculation.

▪ Modulation calculations.

▪ In addition to 45° illumination, the AIM DPM standard allows 30°, 90° and dome illumination.
