ABSTRACT:
Apparatus for thermally printing images, such as color images, on a print medium. The medium is moved repeatedly from a reference position through a printing region, as by rotating the medium on a platen. Thermal print elements are disposed at the print region and are selectively energizable to cause images, such as color images, to be printed. A movable web of thermally transferable material has a run interposed between the print medium and the thermal elements at the print region. In one embodiment, the web is provided with successive frames of respectively different colors of thermally transferable material arranged in repeated sequence. Energizing signals are supplied to the thermal elements representative of the image to be printed; and an image is printed in a color corresponding to the color frame then disposed at the printing region. Successive passes of the print medium are made in order to print images of the remaining colors in the sequence of frames on the web.
