Abstract:
A printing apparatus for selectively printing an image from image data onto any member of a set of photosensitive media, wherein said set comprises at least a first photosensitive medium and a second photosensitive medium, wherein said first photosensitive medium has a relatively low contrast response with respect to said second photosensitive medium, the apparatus comprising:(a) a spatial light modulator for forming an image by modulating a polarization state of an incident light according to said image data, said spatial light modulator having at least a first set of setup voltage conditions for printing onto said first photosensitive medium and a second set of setup voltage conditions for printing onto said second photosensitive medium; (b) an adjustable polarizing component in the path of output light from said spatial light modulator, said adjustable polarizing component having at least a first contrast setting for said first photosensitive medium and a second contrast setting for said second photosensitive medium; and (c) a control logic processor for selectively setting at least said first set of setup voltage conditions for said first photosensitive medium and said second set of setup voltage conditions for said second photosensitive medium.
