UV security ink is a simple, yet cost-efficient means of product security. While on the less complex scale of covert technologies as a whole, UV ink can be rather effective in many cases. It can be used alone or in conjunction with other security features to protect documents, pharmaceuticals, vouchers, coupons, product seals and more against counterfeiting and fraud.
Printing with UV security inks are difficult to detect under natural lighting conditions. But under a UV light (black light) the print jumps out and becomes visible. The UV image can be images, lettering, or even consecutive numbers.
