A method for engraving an image pattern onto an impression die plate utilizes laser engraving and acid attacking techniques. In one embodiment, a brass plate is provided having a nickel coating thereon. A laser removes selected portions of the nickel coating according to a preselected image pattern so as to expose the underlying portions of the brass plate. Upon immersion of the plate into an acid bath, the acid attacks the exposed plate portions so as to present depressions in the plate. Upon removal of the plate from the bath a series of depressions and remaining coating portions on the plate present undulations thereon corresponding to the desired pattern image. This image is then impressed onto a medium, e.g. as a foil or the like. Various materials may be used for the plate, coating and acid bath. An electrically charged chrome coating may also be used with a non-electrically charged chrome being the acid bath.
