Abstract

Die Erfindung betrifft ein Verfahren zur Bestimmung der Feuchtmittelführung einer Offset-Druckmaschine. Für eine sujetabhängige Feuchtmitteleinstellung wird vorgeschlagen, daß ein Einfärben der Druckplatte (6) mit Farbe unter Farbannahme (Tonen) von im Fortdruck­ prozeß an sich farbfreien Flächen vorgenommen wird und daß anschließend eine definierte Feuchtmittelzu­ führung bzw. Vergrößerung der Feuchtmittelzuführung unter Erfassung des Farbabnahmevorganges der tonenden Flächen erfolgt, der als ein Maß für die einzustel­ lende Feuchtmittelführung herangezogen wird. Überdies wird eine Vorrichtung zur Feuchmittelführung ange­ geben. The invention relates to a method for determination the dampening solution guide of an offset printing machine. For a subject-dependent dampening solution setting proposed that the printing plate (6) be colored with color under color acceptance (toning) of in production process is made in itself color-free areas and that subsequently a defined dampening solution Management or enlargement of the dampening solution supply taking into account the color decrease process of the toning Area to be set as a measure of the lent dampening solution guide is used. Moreover is a device for dampening agent management give.
