Can QR codes and barcodes be printed on product labels?

Yes, QR codes and barcodes can be printed on product labels using either flexographic or digital printing, and both formats support either a single repeated code across a batch or a unique, variable code on every individual label when combined with variable data printing.

Standard barcodes, such as those used for retail point-of-sale scanning under GS1 formats, and QR codes linking to a fixed webpage are commonly printed the same way across an entire batch using a standard flexographic or digital print run, since the code does not need to change unit to unit for these applications. Print quality matters significantly for scannability: the code needs sufficient contrast, correct sizing relative to its scanning distance, and clean edges, which is why barcode print quality is often verified against a formal standard such as ISO/IEC 15416 before a production run is approved for retail use.

When each unit needs a distinct code, such as for item-level track-and-trace, serialised authentication, or unique promotional codes, variable data printing on a digital press is required, since this generates a different code for every individual label rather than repeating one design. In either case, the printed code should be tested with the actual scanning equipment it will be read by, whether a retail POS scanner, a warehouse handheld, or a consumer’s phone camera, since substrate colour, gloss, and print resolution can all affect how reliably a code scans in practice.
