Abstract:
A multilayer laminate identification document including an outer layer having a contoured surface image formed therein via laser ablation. The contoured surface image has contours based on a digital monochrome image, and has a first appearance when viewed in reflected light at a first angle and a second, different appearance when viewed in reflected light at a second, different angle. The multilayer laminate identification document is formed by generating a second digital monochrome image with continuous pixel patterns from a first digital monochrome image, and irradiating the surface of the identification document with a laser using the second digital monochrome image as a guide to form a contoured surface image in the surface of the identification document.
