摘要： An imaging system is disclosed that includes an illumination source (40), a diffractive modulator (44), imaging optics (46), and a coherence reduction system (42). The illumination source (40) is for producing an illumination field. The diffractive modulator (44) is for receiving the at least partially coherent illumination field and producing a modulated illumination field. The imaging optics (46) are for directing the modulated illumination field toward an imaging surface (52). The coherence of one of the illumination field and the modulated illumination field is reduced.

摘要： A print drive 41 is present in an electronic pre-press workflow that includes a raster image processor "RIP" 34 and an output device 46 to receive, store, combine and transmit raster data processed by the raster image processor 34. A prepress imposition scheme is created at the front end 40 and processed by the RIP 34 . Prepress imposition parameters 510-519 are used to generate a press sheet template image 102 , which is transmitted to the print drive 41 . The print drive 41 is capable of applying the press sheet template 102 to page raster data 94 on demand to form a multi-page press sheet assembly 98 so that raster images 94 of individual pages 90 remain independent. Among other benefits, this improves electronic prepress workflow by eliminating the need to generate combined raster images of multi-page press sheets to correct or modify a portion of the assembly.

摘要： An apparatus and method for picking a single printing plate (18 1 ) from a stack (20) of printing plates. The apparatus includes a plurality of suction cups (116), a peeler (162), a drive system (166) for displacing the suction cups (116) and the peeler (162) against the surface of the top printing plate (18 1 ) on the stack (20), a vacuum source for supplying a vacuum to the suction cups (116) to secure the suction cups (116) against the surface of the top printing plate (18 1 ), and a system for rotatably displacing the suction cups (116) relative to the peeler (162) to peel a portion of the top printing plate (18 1 ) off of the stack (20). The center line (CL) of rotation of the displacing system (100) is located at a contact point between the peeler (162) and the surface of the top printing plate (18 1 ). This prevents any relative motion of the top printing plate (18 1 ) against the next, underlying printing plate (18 2 ) on the stack (20) during the peeling operation.

摘要： A method for reducing artifacts in a color printed image (15a), that are perceivable by the naked eye, includes using a different imaging beam (39 versus 48) to start imaging each printing plate (13a, 14a) that is used for a different color plane. Alternatively, a different set of imaging beams may be used to image each printing plate (13a, 14a) used for a different color plane. The method does not require manipulating image data. The method diffuses some errors throughout the printed image (15a) and prevents some errors from being imaged and/or printed which reduces or eliminates the visible perception of artifacts.
