Abstract

A method of printing color images which includes the formation of a pattern of three primary color separated halftones of the image from a medium applied to a substrate. The medium is embossed to form a surface relief configuration on each halftone image. Each surface relief configuration reflects one specific primary color at a specific angle. In one embodiment, the medium is applied to a substrate in the pattern of color separated halftone images in a single printing pass by a composite offset printing plate. The medium is then embossed by an embossing plate to create the surface relief configurations thereon. In a second embodiment, the medium is applied to the substrate and embossed by a single plate in a single printing pass. In a third embodiment, the medium is applied to the substrate in a relatively continuous layer and thereafter embossed to simultaneously create a pattern of color separated halftones of the image and a different surface relief configuration on each halftone image. In a fourth embodiment, the medium is applied to the substrate in a relatively continuous layer and thereafter embossed to form a plurality of surface relief configurations thereon. The halftone images are then formed on the embossed medium to produce a full color image by applying a coating over the portions of the medium where the primary colors should not be reflected.
