Abstract
A sheet-fed offset rotary printing machine is used for multicolor printing. A plate cylinder and a rubber blanket cylinder are utilized, as are first and second impression cylinders. Either of these two impression cylinders is operable with the blanket cylinder. Sheets to be printed can have a length corresponding to a nominal diameter, or to twice a nominal diameter. The first impression cylinder has a plurality of controllable gripper systems while the second impression cylinder has at least one controllable gripper system.
Claims11
A sheet-fed offset rotary printing press for multi-color printing comprising:
- a printing cylinder having a first diameter and a number of printing areas;
- a rubber blanket cylinder engaging said printing cylinder and having said first diameter and said number of printing areas, said first diameter being a multiple of a nominal diameter;
- a first, central impression cylinder engaging said rubber blanket cylinder;
- a number of controlled gripper systems on said first, central impression cylinder, said number of controlled gripper systems being not equal to said number of printing areas on said printing cylinder;
- and
- a second impression cylinder, said second impression cylinder having at least one controllable gripper system, said second impression cylinder being in engagement with said rubber blanket cylinder, said first and second impression cylinders being arranged to selectively act with said rubber blanket cylinders.
A sheet-fed offset rotary printing press for multi-color printing comprising:
- a printing cylinder having a number of printing areas, said number of printing areas on said printing cylinder being greater than one;
- a first impression cylinder cooperating with said printing cylinder and having a number of controllable gripper systems, said number of controllable gripper systems on said first impression cylinder being not equal to said number of printing areas on said printing cylinder;
- and
- a second impression cylinder cooperating with said printing cylinder, and having at least one controllable gripper system, said first and second impression cylinders being arranged to selectively act together with said printing cylinder.
