摘要： A rotary printing press is provided. The rotary printing press includes a continuous printing web of material to be printed, at least one printing unit for printing on the printing web, and a cutting device for cutting the web printed by the printing unit. The rotary printing press further includes a traction device located downstream of the furthest downstream printing unit and upstream of the cutting device. The traction device is for applying a predetermined mechanical tension to the printed web discharged from the furthest downstream printing unit and the printing web is a coated paper web. A method for printing is also provided.
