Abstract

Die Erfindung betrifft ein Verfahren zum Befeuchten einer Druckform in einer Bogenoffset-Rotationsdruckmaschine, insbesondere für alkoholarmen oder alkoholfreien Druck.The invention relates to a method for moistening a printing form in a sheet-fed rotary printing press, in particular for low-alcohol or alcohol-free printing.

Die Aufgabe der Erfindung besteht darin, ein Verfahren und eine Einrichtung zu entwickeln, um die Gebrauchsdauer des Feuchtwassers deutlich zu verlängern.The object of the invention is to develop a method and a device to significantly extend the service life of the fountain solution.

Gelöst wird diese Aufgabe dadurch, dass bei der Befeuchtung der Druckform mit einem Feuchtmittelüberschuss gearbeitet wird, derart, dass der Feuchtmittelüberschuss gesammelt, einem zentralen Vorratsbehälter (11) zugeführt und dort konditioniert wird. Der Salzgehalt im Vorratsbehälter (11) wird in vorgegebenen Zeitintervallen gemessen und bei Überschreitung eines prozessbasierten Sollwerts wird entsalztes Frischwasser (21) zugeführt. Bei Unterschreitung des prozessbasierten Sollwerts wird Frischwasser (19) zugeführt, wobei entsalztes und anschließend aufgesalztes Frischwasser (20) zugegeben wird, wenn innerhalb einer prozessbedingten zeitlichen Vorgabe durch Zugabe des Frischwasser der prozessbasierte Sollwert nicht erreicht wird.
Eine für diesen Zweck bestimmte Einrichtung wird beschrieben.

Figure imgaf001
This object is achieved in that is used in the moistening of the printing form with a dampening solution surplus, such that the dampening solution surplus collected, fed to a central reservoir (11) and is conditioned there. The salinity in the reservoir (11) is measured at predetermined time intervals and when exceeding a process-based setpoint desalinated fresh water (21) is supplied. When falling below the process-based setpoint fresh water (19) is supplied with desalted and then aufgesalztes fresh water (20) is added if within a process-related time limit by adding the fresh water, the process-based setpoint is not reached.
A device dedicated to this purpose will be described.
