ABSTRACT:
The present invention is for an imaging processing apparatus (10) for thermal print medium. The image processor apparatus (10) comprises a vacuum imaging drum (300) for holding thermal print media(32) and donor sheets (36) in registration on the vacuum imaging drum (300). A printhead (500) moves along a line parallel to a longitudinal axis X of the imaging drum (300) as the imaging drum (300) rotates. The printhead (500) receives information signals and produces radiation which is directed to the donor (36) which causes color to transfer from the donor (36) to the thermal print media (32). At least part of a surface of the vacuum imaging drum (300) has micropaths over at least a portion of a surface of the vacuum imaging drum (300). In one embodiment the micropaths are produced by sandblasting (330). At least one vacuum hole or slot is located on the surface of the vacuum imaging drum (300), connecting to the micropaths. The micropaths act in cooperation with the vacuum holes (306) to increase the force holding sheets of thermal media (32) and dye donor (36) material to the drum (300), allowing higher rotational speeds.
