Abstract (en)
[origin: EP0653301A1] The invention describes a method and a device for controlling an automatic plate exchange process in a sheet-fed offset printing machine, in which a used printing plate is removed from the gripping region of a clamping rail assigned to the leading edge of the plate cylinder and a new printing plate is then introduced into the opened gripping region, fixing of the in-register position of the newly introduced printing plate taking place before the gripping region is closed (clamped). This method is to be designed in such a way as to result in increased safety and reliability in the course of the plate exchange process. Before it is established whether the newly introduced printing plate lies in register in the gripping region of the clamping rail, it is checked whether the used printing plate has been removed from the gripping region, for which it is established whether the used printing plate is not in an in-register position with its leading edge. <IMAGE>
