ABSTRACT:
A scanning thermal dye printer has a scanning station positioned to scan a color input image and control dye deposited in a dye deposition station that is disposed to reproduce the color input image. A primary filter is adapted to remove a quantity of the color not absorbed by a deposited dye, and at least one variable density filter provides fine control of the light components associated with the deposited dye. A prescanning station determines a color balance for an image and communicates color balance information to the color station controller. The color station controller positions the variable density filter in response to receiving color balance information.
