Abstract
A method for making a secure identification document with multiple images is provided. Information is provided to an information bearing layer, the information constructed and arranged to be capable of providing multiple images when the printed information is viewed at different predetermined angles through an appropriate lens. At least a portion of the information is covered with a layer of a substantially a transparent film material. A lens profile is embossed onto a first portion of the substantially transparent film material, wherein the first portion of the substantially transparent film material comprises an area that is less than the entire layer of substantially transparent film material and wherein the first location substantially coincides with the location of the information. The lens profile forms a lens on a portion of the substantially transparent film material, the lens enabling the information viewed through the lens to display multiple images when the information is viewed at different predetermined angles.
