Abstract: An alignment detection system is disclosed for determining whether a modulated illumination field in an imaging system employing an illumination modulator is mis-aligned. The alignment detection system includes a modulator adjustment unit for providing a test pattern on the illumination modulator, a detector for receiving a modulated illumination field from the illumination modulator, a sampling unit for determining at least two sample values (A and C) for each of two areas of the modulated illumination field respectively, and an evaluation unit for determining whether the value |A?C| is greater than a threshold value.

Abstract: 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.

Abstract: A modulation quality detection system is disclosed for determining the modulation quality of an illumination modulator in an imaging system. The modulation quality detection system includes a modulator adjustment unit for providing a test pattern on the illumination modulator, a detector for receiving a modulated illumination field from the illumination modulator, a sampling unit for determining at least three sample values (A, B and C) for each of three areas of the modulated illumination field respectively, and an evaluation unit for determining whether the value ( A + C 2 ) - B is greater than a threshold value.

Abstract: A method and apparatus for holding recording media against a media support surface of an imaging system using an arrangement of variable cross-section vacuum grooves. Each vacuum groove has a continuously decreasing cross-section along its length. Each vacuum groove has a maximum cross-section adjacent a vacuum port and a minimum cross-section at a distal end of the vacuum groove.

Abstract: The invention involves an internal drum thermal imaging apparatus comprising a support for supporting a receiver material and a donor material in a superimposed relationship. The support includes a cylindrical drum having an inner circumference on which the receiver material is supported against in a bottom layer of the superimposed relationship and the donor material in a top layer of the superimposed relationship. An imaging unit thermally transfers an image from the donor material to the receiver material. An applicator automatically loads and unloads the receiver material and the donor material onto the cylindrical drum comprising an applicator carriage, an attachment device for attaching the receiver material to the applicator and an applicator transport device for transporting the applicator carriage along the inner circumference of the cylindrical drum.

Abstract: An imaging system is provided for imaging media of while supported at an imaging position on a support surfaces. The system includes a loading device configured to move the medium to be imaged along the support surface to the imaging position. During loading, the leading edge of the medium, which extends across the medium width and substantially perpendicular to a direction of movement of the medium, moves in a direction towards a registration device. A registration device is contacted by the leading edge of the medium during loading so as to position the medium in the imaging position on the support surface. A medium securing device secures the medium to the support surface and a perforation mechanism subsequently punches or notches the medium prior to imaging. A drive mechanism is provided to move the perforation mechanism and the registration device, typically prior to loading of the medium, to a position which corresponds to the particular width of the medium to be imaged.

Abstract: A system for holding recording media onto a media support surface, comprises, a media support element including a media support surface and a second side, substantially opposing the media support surface. A plurality of vacuum ports pass from the media support surface to the second side and communicate with a device for drawing air through each of the plurality of vacuum ports to hold the recording media against said media support surface. A sequencing manifold connected between the device for drawing air and the plurality of vacuum ports selectively draws air through a portion of the plurality of vacuum ports over a region substantially matching the size of the recording media.

Abstract: 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.

Abstract: A method and apparatus are provided for orienting a sheet of recording media on a support surface for recording an image onto the recording media in a predetermined location. A registration device, which includes two contacting points for contacting an edge of the media, establishes a registration axis having a know orientation and location with respect to the support surface and with respect to the image to be recorded. A media loading device advances the media across the support surface and orients an edge of the media against the two contacting points of the registration device. At least one of the two contacting points of the registration device is movable with respect to the support surface for adjusting the separation between the two contacting points in accordance with a width of the recording media. The image may also be located at a known location with respect to another perpendicular edge of the recording media.
