PIXEL PREHEAT SYSTEM FOR AN AUTOMATED THERMAL TRANSFER DEVICE ABSTRACT OF THE DISCLOSURE A pixel preheat system for a thermal transfer device in which a selected image is transferred from a strip of. color carrying ribbon to a strip of image carrying tape achieves precise control of the temperature of the individual pixel heating elements in a thermal printhead by combining the pixel data values just printed with the pixel data values to be printed to generate a pixel preheat value whenever either of the pixel data values is off or white. The present invention maintains the temperature of the individual pixel heating elements closer to the transition temperature of the thermal transfer ribbon and uses fewer circuit components.
