    摘要: A method and apparatus for determining the alignment of printing plate mounted on an imaging drum, and applying an image to a printing plate while maintaining registration and alignment between the image and a reference edge of the printing plate include mounting the printing plate on a plate making machine and then determining the locations of at least one point on the reference edge. The locations of two or more points are used to determine a transformation that is applied to image data to yield transformed image data. The transformed image data is used to image the printing plate.

    摘要: A method and apparatus for determining the alignment of printing plate (14) mounted on an imaging drum (12), and applying an image to a printing plate while maintaining registration and alignment between the image and a reference edge (15) of the printing plate include mounting the printing plate on a plate-making machine (10) and then determining the locations of at least two points on the reference edge. The locations of two or more points are used to determine a transformation that is applied to image data to yield transformed image data (27). The transformed image data is used to image the printing plate. A method and apparatus for determining the locations of the points using backlighting avoids errors encountered in illuminating from the top.

    摘要: A method for aligning the leading edge of printing plate (110) to an axially disposed slot (70) in a cylindrical surface (30) of an imaging drum (20) comprising at least one printing plate clamp (90) having a clamp surface (100) disposed parallel to the slot, the method comprising straightening (210) the leading edge against the clamp surface and positioning (220) the leading edge to protrude over the slot by rotating the imaging drum under the plate. The straightening comprises resting (200) the leading edge of the plate on the cylindrical surface of the imaging drum and rotating the imaging drum about its cylindrical axis (60) to contact with the clamp surface a point along the leading edge of the plate and to rotate the plate until its leading edge is in alignment with the clamp surface.

    摘要: An apparatus for mounting and demounting a materials sheet onto and from a cylindrical surface of a drum (10) has clamps (40) pivotably arranged upon the sheet materials drum. The clamps have a first region (80) and a second region (70) either side of a pivot axis. The second region (70) clamps the materials sheet to the cylindrical surface (20) of the drum. A backbone (120) extends along the length of the drum and is removably attached to the drum. Push rods (90) movably arranged on the backbone are capable of being operated to push against the first region of the clamps to pivot the clamps to move the second region of the clamps. Any existing clasped materials sheet is thereby unclasped from the cylindrical surface.

    摘要: The calibration of an imaging system is adjusted for geometric distortion of an image formed by a group of imaging channels on a media supported on a media support. The media support includes a plurality of individually spaced reference features disposed on a surface of the media support and a change in an expected position of at least one of the reference features is determined. Activation timing of the channels is adjusted in accordance with such changes. The imaging channels can be supported on a movable carriage and movement of the carriage can be adjusted in accordance with such changes.
