Overview
About Colour Shifting Inks
Colour shifting inks provide an overt security effect that can be inspected with the naked eye and without specialized equipment. Their colour changes as reflected light or the viewing angle changes, making documents and products easier to authenticate. The inks can be applied to paper, PVC, PET, PC, and other substrates by screen or flexo printing. Physical and chemical performance testing supports their use in high-security work. Custom forensic tracers and taggants can be included when an additional covert layer is required.
