Glitter, pearlescent, fluorescent, thermochromic—even the names of specialty inks raise the specter of something exciting.

Rad-Cure offers UV and aqueous bichromatic inks for flexo application on paper and most plastic substrates. When viewed at different angles, these inks will change from a hazy white to a color. They are also available with two or three color-shift effects. Bichromatic inks can be used to simply enhance visual appeal or can provide visual security without the need for a secondary reader. As another security measure, Lorenz adds that the color-shifting features cannot be reproduced by a color copier or digital scanner.
