ABSTRACT:
A single pass multicolor thermal transfer printer for recording color images on plain paper by transferring spots of different colored materials from a carrier sheet as it and a sheet of paper are moved across a printhead in contiguous relation. The printhead includes a plurality of individual thermal elements that are selectively energized in timed relation to transfer colored materials from discrete areas of the carrier to the paper as the sheets pass over the printhead. The carrier includes separate, repeating patterns of four different color materials--three primary colors plus black--permitting the formation of multicolor images by energizing the appropriate elements as areas of the desired color materials are moved into registration with them.
