About Ultracode
Ultracode is a colour 2D barcode that uses up to eight colours to encode significantly more data than a monochrome code of the same size.
Valid input
- Uses 8 colours - the printer and substrate must reproduce all 8 distinctly or the scanner will fail.
- Do not use on yellowed paper, thermal labels that fade, or greyscale reproductions.
