Abstract

Die Erfindung betrifft ein Verfahren zur Festlegung eines in einem farbfreien Bereich liegenden Meßortes (17) für die Erfassung der Feuchtmittel-Schichtdicke auf der Oberfläche (3) einer Offset-Druckplatte (2), wobei ein Meßkopf (4) im Suchlauf die Plattenoberfläche abscannt und eine Auswertung der dabei ermittelten Meßdaten erfolgt; sie schlägt zur Erzielung einer insbesondere positionierungstechnisch optimalen Arbeitsweise eine Auswertung der Meßdaten derart vor, daß der Meßort (17) in einer Vertikalzone (8) der Offset-Druckplatte (2) mit möglichst geringer mittlerer Flächendeckung liegt. The invention relates to a method for determining a a color-free area of the measurement site (17) for the detection the dampening solution layer thickness on the surface (3) one Offset printing plate (2), with a measuring head (4) searching the plate surface scanned and an evaluation of the determined Measurement data takes place; it strikes to achieve one in particular, optimal working in terms of positioning an evaluation of the measurement data in such a way that the measurement location (17) in a vertical zone (8) of the offset printing plate (2) medium area coverage is as low as possible.
