Abstract
A method for aligning a printing plate, prior to imaging, on a platesetter includes the steps of: determining a leading edge of the printing plate; feeding the printing plate by the leading edge onto punch equipment resident on the platesetter; centering the printing plate on the platesetter along the leading edge; punching one or more notches along the leading edge of the printing plate according to a predetermined punch configuration; securing the leading edge and a trailing edge to a support surface of the platesetter with respect to registration pins located on platesetter; determining a location of a vertical edge of one of the notches, the vertical edge defined as being perpendicular to the leading edge; and determining a location with respect to the vertical edge of the one notch for transferring an image onto the printing plate.
