Abstract

Bei einem Verfahren zur Überwachung der Feuchtmittelführung bei einer Offset-Druckmaschine werden an sich unbedruckte Flächen im Bereich von Rändern von vorgegebenen Farbflächen mit Hilfe eines opto-elektrischen Wandlers (3) abgestastet und die durch die Abtastung entstehenden Signale ausgewertet. Vorzugsweise erfolgt die Abtastung bei Volltonfeldern (MF) eines Druckkontrollstreifens (MS). Das Verfahren ist sowohl zur Überwachung an sich als auch zur automatischen Regelung der Feuchtmittelführung geeignet. In a process for monitoring the dampening solution flow in an offset printing machine, unprinted are in themselves Areas in the area of edges of given colored areas scanned with the help of an opto-electrical converter (3) and the signals resulting from the sampling are evaluated. The scanning is preferably carried out with solid tone fields (MF) Print control strip (MS). The procedure is both for Monitoring itself and for automatic control of the Suitable for dampening solution.
