Abstract
The present invention is for an image processing apparatus (10) for sheet thermal print media. The image processing apparatus (10) comprises a vacuum imaging drum (300) for holding thermal print media (32) and dye donor sheet material (36) in registration on the vacuum imaging drum (300). A printhead (500) moves along a line parallel to the longitudinal axis (X) of the vacuum imaging drum (300) as the vacuum imaging drum (300) rotates. The printhead (500) receives information signals and produces radiation which is directed to the dye donor sheet material (36) which causes color to transfer from the dye donor sheet material (36) to the thermal print media (32). The vacuum imaging drum (300), having media contours (328) on the outer surface to facilitate holding media onto a vacuum imaging drum (300) revolving at high speeds.
