security ink pigment

OVI (Optically Variable Ink) pigments are the primary authentication pigment wholesale solution for brand protection and security printing — producing dramatic color-shift effects that cannot be reproduced by scanning, photocopying, or standard printing. At Kolortek, our Chromashift series delivers verified color travel across 17+ shift combinations, meeting the rigorous optical and durability standards required by security printers and brand owners worldwide. For teams managing a bulk order of OVI pigment, we supply in flexible volumes from R&D samples through full commercial production runs.
