Abstract
A thermal dye transfer apparatus includes a laser which illuminates an image or pattern produced by a liquid crystal display. This laser image is projected onto a dye carrying donor. The donor absorbs heat from laser light and dye transfers by sublimination from the donor to the receiver to form the image or pattern in the receiver.
