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: 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: 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: An illumination modulator correction system is disclosed for adjusting the operational parameters of an illumination modulator in an imaging system. The correction system includes a modulator pattern unit for providing a test pattern on the illumination modulator, a modulator adjustment unit for permitting an actuation voltage on the illumination modulator to be changed through a range of actuation voltage values, a detector for receiving a modulated illumination field from the illumination modulator, a sampling unit for determining at least one sample value for at least one area of the modulated illumination field, and an evaluation unit for determining a minimum sample value within the range of actuation voltage values of the illumination modulator.

Abstract: A system is disclosed for determining whether an imaging system is in a proper operating condition. In an embodiment, the system includes an illumination modulator for providing a desired modulated illumination field at an image surface, a detection unit including a slit opening for receiving a portion of the modulated illumination field, an average power sample unit and a variation power sample unit. The average power sample unit is for determining the average power sample value of the modulated illumination field as the modulated illumination field is moved with respect to the slit opening and for determining whether the average power sample value has changed significantly since a previous scan. The variation power sample unit is for determining the variation in power sample values of the modulated illumination field as the modulated illumination field is moved with respect to the slit opening and for determining whether the variation in power sample values has changed significantly since a previous scan.

Abstract: The present invention provides an input roller system for displacing a printing plate toward and against a plurality of registration pins located on an external drum of an imaging system. The input roller system deskews the printing plate relative to the registration pins.

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.
