Abstract
The present invention is for a vacuum imaging drum with vacuum holes for maintaining a boundary layer in an image processing apparatus (,). The image processing apparatus (,) with a vacuum imaging drum (,) for holding thermal print media (,) and donor sheet material (,) in registration on the vacuum imaging drum (,). A printhead (,) moves along a line parallel to the longitudinal axis (X) of the vacuum imaging drum (,) as the vacuum imaging drum (,) rotates. The printhead (,) receives information signals and produces radiation which is directed to the donor sheet material (,) which causes color to transfer from the donor sheet material (,) to the thermal print media (,). The vacuum imaging drum (,) provides vacuum on its surface by means of a first plurality of holes. A second plurality of holes maintains a boundary layer (,) of air along the drum surface.
