About Light Sensitive Inks

Light sensitive inks change colour when exposed to sunlight, UV light, or blacklight and return to their transparent state when the light source is removed. This reversible visual effect allows documents, labels, cards, and packaging to be checked without specialist equipment. The inks are compatible with offset, screen, flexo, and rotogravure printing. They adhere to paper, plastic, metal, and other commonly used substrates. Colours can be customized, while embedded taggants and chemical identifiers can add further security and traceability.
