Abstract

A method of establishing a measuring location lying in an ink-free area for determining the thickness of a layer of dampening medium on the surface of an offset printing plate, which includes scanning the surface of the plate in a search run with a measuring head, and evaluating the thus obtained measurement data in a manner that a measuring location lies in a vertical zone of the offset printing plate with the smallest possible average area coverage, and a device for performing the method.
