  • Method and apparatus for thermal printing of longer length images by the use of multiple dye color patch triads or quads
    Patent number: 6961075
    Abstract: A method and apparatus of thermally printing an image on a receiver by (a) printing a first sub-image on a first region of the receiver with a first dye-donor patch of the first color and (b) printing a second sub-image on a second region of the receiver with a second dye-donor patch of the first color, wherein the first and second regions of the receiver have a partial overlap region. The first and second sub-images form the image which is longer in length than either of the first and second dye-donor patches. Pixels in the overlap region are printed with varying gray levels during both of steps (a) and (b) and pixel locations in the overlap region are printed by overlapping a partial pixel printed during printing step (a) with another partial printed during printing step (b).
