Abstract
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.

Method of optimizing a reproduction of a picture copy, which comprises 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 and shapes of the elementary cells so that a region of overlap between an inscribed and an adjacent non-inscribed elementary cell, respectively, is minimal.
