Photochromic Ink

Photochromic inks change colour dramatically when placed in daylight. The colour change is reversible creating fun promotional products which can used almost indefinitely such as colourful UV light-sensitive stickers, cards, transfers and fabric patches for both children and adults. A number of bright colour changes are available.

Our photochromic inks can also be used as a UV warning device. Caution is necessary when sunbathing; Incorporated onto a card the UV sensitive meter darkens in accordance to the intensity of the sun´s rays – perfect for Summer promotions.
