Questions tagged [barcode-printing]

The generation of barcode symbols (1d & 2D) on printed media.

This tag deals with the generation of barcodes on print media. The proper output of a barcode determines its legibility for scanning devices. Many factors influence a barcode's readability including: reflectance, contrast, maintenance of quiet zone, adherence to specifications, printing technology, print media, physical defects. Barcode verification equipment exists to grade barcodes according to the international barcode quality specification ISO/IEC 15416 (1D) and ISO/IEC 15415 (2D). Suppliers of barcode labels and suppliers of products that must meet customer labeling specifications are often contractually obligated to submit samples for verification.
