Abstract

In order to obtain satisfactory smoothness and sharpness in images as regards the sublimation-type thermal dye transfer printer, the following problems are discussed to be compensated. (1) Unevenness of optical density in main scanning direction (2) Drop of voltage depending on the number of driven heating elements (3) Thermal effect due to adjacent heating elements or preceding lines (4) Time lag at heating-on and off We estimated the thermal influence of the above problems by numerical computations. As for the experiments, we compensated the energy applied to the heating elements. As a result, we have obtained good smoothness and sharpness in images.
