PROCEDURE TO ESTABLISH A MEASURING POINT TO DETERMINE THE THICKNESS OF THE LAYER OF MOISTENING AGENT ON AN OFFSET PRINTING PLATE

摘要

The invention relates to a procedure to establish a measuring point lying in an ink-free area for the registration of the thickness of the layer of moistening agent on the surface of an offset printing plate, whereby a measuring head scans the plate surface in a search run, and an evaluation of the measurement data thus obtained is performed; the invention proposes an evaluation of the measurement data in order to obtain an optimal working method, in particular as regards positioning technology, in such a manner that the measuring point (17) lies in a vertical zone (8) of the offset printing plate (2) with the smallest possible average area coverage.
