Abstract (en)
An engraved identification card with a multi-colored image engraved thereon includes a card with a base ply (12). a top ply (14), and a plurality of colored pies (18, 20, 22, 24, 26) between the top ply and the base ply. Each colored ply is a color different from the color of each adjacent ply. The card has a multiplicity of engraved cavities where each cavity has a depth selected to expose one or more portions of one or more of the top, colored, or base plies. The resultant multiplicty of exposed portions of the different pies cooperate together to form the colored image on the card. The cavities may be a multiplicity of individually drilled holes (28, 30) or may be a multiplicity of longitudinal grooves or furrows (52)
