Abstract

A printing device for the production of a plurality of print jobs having different image contents. The execution time, as well as the correspondingly necessary working steps for producing the printing form having the different image contents of the individual print jobs is intended to be optimized or minimized, so that a printing machine which is operated in accordance with this method or is effectively connected to such a data processing device is able to produce the largest possible number of print jobs in a predefined time. According to the invention, this is achieved in that the image contents of the various print jobs are compared with one another pixel by pixel and in the respective color separations, whereupon the defining of the execution sequence for producing the print jobs is performed to the effect that, for example, the number of working steps needed to rewrite an existing printing form for the next printing form and/or the execution time needed for this, is minimal.
