A method and a diagnostic device for a printing press are described, wherein data is automatically transmitted by a central data processor of the printing press to a locally distanced central data processor when a threshold value is upwardly transgressed, downwardly transgressed or reached. The data is preferably assessed prior to the evaluation and/or the transmission to the remote central data processor. In this way, a simple telediagnostic service of the printing press is possible.

Method of optimizing a reproduction of a picture copy includes scanning a picture copy optoelectrically for generating scanning signals, in accordance with the scanning signals, electronically screening the picture copy and inscribing a recording medium so that one of a plurality of screen fields on the recording medium corresponds to one or more scanning signals of the picture copy, forming each of the screen fields, respectively, of a plurality of elementary cells, and determining relative locations of the elementary cells so that a region of overlap between an inscribed and an adjacent non-inscribed elementary cell, respectively, is minimal.
