Abstract
Abstract Methods of color printing of solid areas to create a frosted or shimmering effect including the combining of a layer of colored ink with a layer of finely divided white pigment, optionally supplemented by a small amount of finely divided metallic pigment. In one of the methods, the ink layer is first deposited, and the white pigment layer is applied thereover, using a bronzing machine in which the amount of white pigment applied is carefully controlled to prevent opacity. In another method, the white pigment layer is first applied, and is overprinted with a transparent colored ink.
