ABSTRACT:
A process and a device for register-correct positioning of printing form sleeves on printing cylinders of a rotary printing machine, each with a pressure gas cushion producible for shifting the elastically expandable printing form sleeve on the printing form cylinder. In order to provide quick register-correct positioning of the printing form sleeves without placing particular demands on the operating personnel, the positions of the printing form sleeves fitting tightly onto the printing cylinders are determined and then the printing form sleeves are individually set and released using the pressure gas cushion of the particular printing cylinder. Then the printing cylinder is turned relative to the printing form sleeve by its angular deviation relative to the register-correct position to be realized. Subsequently the printing form sleeve is again released as well as set relative to the printing cylinder by turning off of the pressure gas cushion.
