Printing machine i.e. sheet-fed rotary press, has computer executing reference/actual value-comparison and controlling actuators in case of established deviations such that established geometry deviations are minimized
摘要
<p>The machine i.e. sheet-fed rotary press (15) has a printing unit including a cylinder (6) covered with a hoist. Actuators (3) change the hoist in an axial and/or circumferential direction of the cylinder in its geometry. An image inspection device (19) is provided for geometrical measurement of printed sheets (20), and a computer (18) processes the measuring result. The computer executes a reference/actual value-comparison and controls the actuators in case of established deviations in such a manner that the established deviations are minimized.</p>
