Abstract
A method for printing an identification card includes printing an image on a surface of the identification card and depositing a first overlayer onto the surface of the identification card. Ridges are created in the first overlayer. A second overlaminate layer is deposited over the first overlayer. The second overlaminate layer includes ridges created by the ridges in the first overlayer such that the ridges create a visible pattern on the identification card.
