Belgium-based Dotrix has joined forces with Swiss security specialist AlpVision to provide a digital watermarking system for invisible personalisation and anti-counterfeiting of packaging and labels.

Based on AlpVision’s Cryptoglyph technology, the system enables encoded data to be printed in the form of indelible pixels that are invisible to the naked eye.

The digital watermark looks like the grain of the paper and can be economically overprinted on any underlying graphical design including white paper.
