Photochromic inks change colour dramatically when placed in daylight. The colour change is reversible creating eye-catching T-shirts which reveal colours when you go outside, and fun promotional products 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 or when outside in the summer; Incorporated onto a card, the UV sensitive meter darkens as the sun’s UV rays become more intense – perfect for Summer promotions.
