Printing press and method for register correction

Abstract

The invention relates to a drive device for a printing press (100), especially a shaftless printing machine by intaglio engraving, which comprises a plurality of individually driven printing groups (111 to 114) provided with linear register adjusting devices. The first printing group is provided with means for simultaneously adjusting the linear register adjusting devices of all printing groups (111; 111, 112; 111, 112, 113) mounted upstream of a first printing group (112; 113; 114) or with means for simultaneously adjusting the linear register adjusting devices of the first printing group (112; 113) and of all printing groups (113, 114; 114) mounted downstream of the first printing group (112; 113) in order to adjust a register variation (ΔR2, ΔR3, ΔR4) on the first printing group. The invention also relates to a method for adjusting a misalignment (ΔR2, ΔR3, ΔR4). According to said method, a material (101) is treated in subsequent treatment steps (110 to 115) and the misalignment (ΔR2, ΔR3, ΔR4) of the material is adjusted with respect to a first treatment step (111 to 115). The misalignment (ΔR2, ΔR3, ΔR4) is adjusted by changing the position of all treatment steps (110; 110, 111; 110, 111, 112; 110, 111, 112, 113; 110, 111, 112, 113, 114; 110, 111, 112, 113, 114, 115) upstream of the first treatment step (111; 112; 113; 114; 115) in the treatment sequence or by changing the position during the first treatment step (111; 112; 113; 114) and all treatment steps (112, 113, 114, 115; 113, 114, 115; 114, 115; 115) downstream of the first treatment step in the treatment sequence.
