Abstract
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 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 (). 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.
