Printed Features

Gradient UV security printing (text and images), which is invisible under daylight, is clearly visible under a UV light source (short 254μm or long 365μm). Gradient UV printing can incorporate any color in the spectrum, including white. ITW Security Division is the only company to use UVC inks in security laminates, making duplication nearly impossible.

Imaprotek® is a polychromatic image, derived from a photograph, using proprietary technology. It is invisible under daylight yet vibrantly visible when exposed to UV light.

Photochromic printing becomes visible with the naked eye after activation by daylight or a flashlight. It disappears after a few minutes when no longer exposed to light.
