Abstract:
1. A reflex-type digital offset printing system for generating a full color image on a print medium in response to image data including a plurality of single-color image data portions, the printing system comprising: one or more feed rollers forming a print medium feed path extending in a process direction; a plurality of single-color imaging systems arranged in series along the print medium feed path, each of said single-color imaging systems including: modulated light field, and arranged to concentrate said modulated light field in an elongated scanning region of the outer imaging surface such that the concentrated modulated light portions remove said fountain solution from said elongated scanning region to produce an elongated scan line image that is aligned in a cross-process direction; and a system controller for coordinating transmission of said single-color imaging data portions to said spatial light modulators such that single-color image portions are successively transferred in a superimposed manner onto the print medium by the plurality of single-color imaging systems, whereby said full color image is generated on said print medium.
