Laser ablation for latent image indicia

Abstract:

A system and method for creating latent image indicia that includes a variable mark. The latent image indicia is made of pigmented ink that can only be viewed when illuminated with a specific frequency of light. The pigmented ink is printed in a solid patch by a conventional printing process. The variable mark in the pigmented ink is created by laser ablation of the pigment. The laser ablation is done after the ink printing as a separate step.
