  • Preventing crease formation in donor web in dye transfer printer that can cause line artifact on print
    Patent number: 6859221
    Abstract: A thermal printer capable of preventing crease formation in a dye transfer area of a dye donor web that can cause a line artifact to be printed on a dye receiver during a dye transfer from the dye transfer area to the dye receiver, includes a print head having a bead of selectively heated resistive elements that make contact across the dye transfer area of the dye donor web and opposite edge areas of the dye donor web that are alongside the dye transfer area as the dye transfer area and the edge areas are progressively advanced under a longitudinal tension over the bead of resistive elements.
    Type: Grant
    Filed: March 18, 2003
    Date of Patent: February 22, 2005
    Assignee: Eastman Kodak Company
    Inventors: Zhanjun J. Gao, Robert F. Mindler, John F. Corman
