Abstract

A method of registration correction by turning a flexible plate about a point on a cylinder of a press, which includes determining data regarding a deviation from registration of a defined register rotation in at least one of a circumferential, side and angular position of the plate from a specimen made from the plate, and issuing adjustment commands initiating adjustment operations in devices provided in the press for respectively turning the plate and for effecting circumferential and side register, the adjustment commands taking into account the determined data, so as to finally correct the register of a pattern produced by the printing plate.
