Abstract

Die Erfindung betrifft ein Verfahren zur Regelung von drucktechnischen Prozessen, insbesondere zur Schnittregisterregelung oder Farbregisterregelung oder Farbdichteregelung an einer Druckmaschine, wobei zur Ermittlung mindestes eines Istwerts (11) unmittelbar das gedruckte Druckbild mit Hilfe mindestens eines Sensors vermessen wird, wobei der oder jeder gemessene Istwert (11) mit jeweils einem druckvorstufebasierten Sollwert (12) verglichen wird, und wobei auf Basis einer aus dem oder jedem Istwert (11) und dem jeweiligen Sollwert (12) ermittelten Regelabweichung (13) ein Stellsignal (15) für den zu regelnden drucktechnischen Prozess (10) ermittelt wird. Erfindungsgemäß wird der oder jeder druckvorstufebasierte Sollwert (12) aus Druckvorstufedaten (16) sowie unter Berücksichtigung von Daten (17) über die Charakteristik des Sensors, mit dessen Istwert der Sollwert verglichen wird, ermittelt.

The invention relates to a method for controlling printing processes, in particular for cutting register control or color register control or color density control on a printing machine, wherein at least one of the actual value (11) directly the printed image is measured using at least one sensor, wherein the or each measured actual value ( 11) is in each case compared with a pressure-preset-based setpoint value (12), and based on a control deviation (13) determined from the or each actual value (11) and the respective setpoint value (12), an actuating signal (15) for the printing-technical process to be controlled (FIG. 10) is determined. According to the invention, the or each pressure pre-stage-based setpoint value (12) is determined from prepress data (16) as well as taking into account data (17) on the characteristic of the sensor with whose actual value the setpoint value is compared.
