摘要： The present invention eliminates artifacts in an image formed using a plurality of imaging sources. Visible seams in the image are eliminated by randomizing the stitch point between the scan lines produced by each imaging source. The randomization may be optimized by additionally applying a method for relocating the random stitch point based on the data content of the scan line, adjacent scan lines, and other criteria. The present invention further compensates for in-scan and cross-scan errors caused by thermally induced errors, spinner synchronization errors, mechanical misalignment, and other factors associated with the use of a plurality of imaging systems. A photodetector system, comprising a mask having a pair of triangular openings, provides measurements of the in-scan and cross-scan errors.

摘要： A system for scanning a surface includes a radiation emitter configured to emit at least one beam of radiation, and a rotating deflector for deflecting the beam(s) onto a scanning surface. The deflector is movable along a translation axis to modify the path of the deflected beam(s) and thereby correct for any mispositioning of the beam(s) with respect to the scanning surface.

摘要： The primary function of the optional handler is to make plates available on demand to the imaging engine. A multitude of plates are stored inside cassettes and these cassettes are loaded into the handler. There may be up to four cassettes residing in the handler. Inside a cassette there may be a protective interleaf sheet, sometimes called a slip sheet, between each plate which is removed by the handler and discarded. The handler receives commands from the engine control sequencer which provides instructions as to what cassette needs to be accessed to make a plate available to the picker mechanism so the plate may be conveyed to the imaging engine. Conversely the handler provides status information to the engine to make full interaction with the system possible.

摘要： An apparatus is provided for positioning a plurality of cassettes within an automated printing plate handler. In a plate handler, a plurality of cassettes each contain a supply of printing plates for delivery to an automatic plate-recording device. The apparatus includes a separate support table for supporting each of the plurality of cassettes within the plate handler and an elevator device for moving each of the support tables along a vertical axis of the automated plate handler. The automated plate handler is configured to automatically position a selected cassette in a first position to facilitate removal of the cassette from the handler. The plate handler further includes a platform, which substantially forms an extension of the support table supporting the selected cassette in the first position. The platform provides a second position, at which the selected cassette is to be one of, loaded or unloaded. The selected cassette may be filled with a new supply of plates on the platform or the selected cassette may be removed from the platform and replaced by a another cassette.

摘要： A scanning system for scanning an imaging surface includes a radiation emitter configured to emit a beam of radiation directed towards a deflector for scanning the beam onto the imaging surface. A detector detects any misalignment of the beam with respect to the deflector. A driver moves a correction element substantially perpendicular to the beam axis of the correction element to correct for the detected misalignment during scanning of the imaging surface.

摘要： A correction element assembly for correcting misalignment of a beam of radiation with respect to a location on a target, includes a housing having a correction element fixedly mounted therein. A flexure is attached to the housing and at least two drive devices are disposed radially around the housing. Each of the drive devices is operable to apply a force to the housing to thereby deflect the flexure causing the housing to move such that said correction element moves in a cyclic fashion about its beam axis.
