Optical Variable Ink

Optical variable ink (OVI), also called colour-shifting or chameleon ink, changes colour as the viewing angle changes — for example green to blue, red to gold or gold to green. Because the effect cannot be reproduced by scanners, copiers or standard printing, OVI is one of the strongest anti-counterfeiting features available and is used on banknotes, passports, certificates, tax stamps, pharmaceutical packaging and premium brand labels.Canink supplies OVI for screen printing, offset printing and UV flexographic printing, as well as magnetic optical variable inks (OVMI) that combine a colour shift with a machine-readable magnetic signature. Product pages list the available colour pairs, recommended substrates and pack sizes.
