Abstract:
A single station single satellite offset printing machine for printing a sheet in compact design, the machine comprising:a single, central multiple function cylinder, said multiple function cylinder structured as common a counter-pressure cylinder, an intermediate transfer cylinder and a sheet transportation cylinder; a feed system engaging said multiple function cylinder at an input side thereof; an output system engaging said multiple function cylinder at an output side thereof substantially opposite to said input side; at least four satellite printing groups for front side printing which are disposed about said multiple function cylinder, as seen in a rotational direction thereof, between said feed system and said output system, each of said at least four satellite printing groups having an image plate carrying cylinder and a blanket carrying intermediate transfer cylinder; at least one additional satellite printing group for at least single-color back side printing disposed, as seen in the rotational direction of said multiple function cylinder, after said output system and before said feed system, said at least one additional satellite printing group including at least one image plate carrying cylinder for transferring ink to said multiple function cylinder; and at least one gripper system disposed on said multiple function cylinder to grasp the sheet for printing of all printing groups, on both the front and back sides of the sheet, with only one single gripper bite and in only one printing cycle, wherein the gripper system remains closed until completion of the printing process on both sides of the sheet.
