ABSTRACT:
A method is shown for photoengraving locator apertures on a single plate or a series of flexible printing plates that form a set of color printing plates simultaneously with the production of the raised printing surfaces on the faces of the plate or series of plates. These locator apertures are used on a novel apparatus to support the plates on a common locator roll. The locator roll with an etched plate draped over it, is held by the apparatus to be precisely aligned with a plate roll or printing roller having a sticky back surface thereon. The apparatus for holding the locator and plate rollers, cooperates with the respective rollers to assure the precise alignment of the printing plate with its plate roll during the plate mounting process.
