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.

System for controlling the automated printing plate change process in

A control device for a printing machine is described, in particular a sheet-fed offset press, having a movable operating element and a device which senses the movements thereof, as well as a downstream electronic valuation system. Such already known control devices, which are equipped with a rollerball, joystick or mouse as operating element, are to be improved with regard to ergonomic operability. This is achieved according to the invention by designing the operating element as a wheel mounted capable of rotating about an axis. The movement of this wheel is sensed by an electronic evaluation system, and highlights selectable menu items in accordance with a prescribed sequence on a display device. After the desired menu item has been marked by rotating the wheel forward or backward, the desired function is initiated by actuating a command initiation key.
