Optical Variable pigments will show completely different colors when changing the viewing angle under sunlight. It has very strong optical variable characteristics and obvious chromatic aberration. These pigments allow for usage in intaglio, gravure, and rotary screen inks. In addition to color-shifting pigments, we also manufacture pigments that are used as a taggant material in intaglio, screen, gravure, or offset type inks. We usually used it in the security printing ink, coding, and brand protection industry.
