Abstract
A method of operating a printing machine and a printing machine apparatus in which basic knowledge about the interaction between operating media in the printing machine is obtained through printing trials or during production. This knowledge is stored in an expert system and made available for the printing operation or else for the production of the printing plate. The expert system is preferably a self-teaching system. For color reproduction, basic calibrations are carried out in a first quality step, in a second step, the imaging operation is adapted to the areas and half tones to be imaged, and ink-density regulation is carried out in a third step.
