ABSTRACT:
A printing press comprises an impression cylinder and an intaglio cylinder each having a notched portion and an effective impression area; an eccentric bearing for supporting the impression cylinder; a lever locked on one end side to the bearing; a hydraulic cylinder for acting on the other end side of the lever to turn the bearing; a pressure transducer for detecting pressure which acts on the hydraulic cylinder when the impression cylinder is pressed against the intaglio cylinder; a display device for displaying a printing pressure between the impression cylinder and the intaglio cylinder that has been calculated from a detection signal produced by the pressure transducer when the notched portions of both cylinders face each other, and a detection signal produced by the pressure transducer when the effective impression areas of both cylinders face each other; and adjusting screw and threaded shaft for adjusting the pressure of contact between the impression cylinder and the intaglio cylinder by changing the position of the hydraulic cylinder.
