Abstract

A system is disclosed for controlling the automated printing plate change process in a printing machine, especially a sheet-fed offset printing machine having one or more printing units, wherein each printing unit includes a device for automatically changing the printing plate. The system allows the printing plate change process to be monitored by an operator from a central work location. According to the invention, a human-machine interface computer evaluates the signals transmitted by the control system in order to gather information which is displayed on a visual display device. The human-machine interface then displays the individual stages or working steps of the printing plate change process in the form of graphical user interface icons. Also displayed are the location and type of fault that occur during the plate change process.
