Abstract

A communication process and accompanying apparatus for enabling communication between different areas of the printing process, e.g. between the preliminary printing stage and the printing press, in either direction so that data for regulating the printing press can be obtained from data which does not depend on the type of printing press and the data to be printed which are received from the preliminary printing stage can be influenced by the printing press itself. The apparatus has a communication structure formed by a central main data processing station, with which a plurality of printing units of the printing press are interlinked for joint preparation of a job, and a decentralized data processing substation for each area of the printing process which can be connected in turn with the main data processing station. The connection between the substations and the main station is formed by device-independent interfaces which allow data to be transferred in either direction.
