Abstract: This invention shows a reverse angle doctor blade adapted to be adjustably mounted to cooperate with the anilox roll of a flexographic printing press. The doctor blade is carried in an arcuate holder and may be adjusted angularly relative to the anilox roll in the arcuate seat and the arcuate holder itself can be adjusted toward and away from the anilox roll to control the exact parallel positioning of the doctor blade's edge against the surface of the roll.

Abstract: A preassembled set of embossing rolls is shown. The embossing roll assembly is completed and tested at a work station away from a press line and thereafter the assembled set of rolls is transported to the press line for installation whereby down time on the press is avoided while the precision assembly of the matched pair of rollers is accomplished elsewhere.

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.
