MULTI-COLOR LASER-ETCHED IMAGES

A color image is fused on a hard surface by a laser beam. A first color layer of toner particles is fused in accordance with a first color separation of a color image at a first screen angle. A second color layer of toner particles is fused in accordance with a second color separation of a color image at a second screen angle. A third color layer of toner particles is fused in accordance with a third color separation of a color image at a third screen angle. A fourth color layer of toner particles is fused in accordance with a fourth color separation of a color image at a fourth screen angle. The screen angles and offsets of the focal point of the laser beam are selected for each color to optimize the colors fused onto the surface.
