ABSTRACT:
A process of multicolor printing where a first sheet with a layer of a first color material thereon has a portion of said first color material destroyed by a laser to leave a first image of said first colored material. The first image is then transferred to a permanent support. A second sheet with a layer of a second color material has a layer applied thereto to leave a second image of said second material, which second image is also applied to the premanent support to make a combined image. The same procedure can be followed with third and fourth colored materials to provide third and fourth images superimposed over the first and second images.
