Abstract

A printing press has at least one first printing tower with at least one first printing unit that has several offset printing couples which are usable to print on one or on both sides of a first web which runs through the first printing unit substantially from the bottom to the top. The web is printed in multiple colors in the first printing tower. A dryer is arranged downstream of the first printing unit and along the conveying path of the first web. A former structure, with at least one former through which the web runs, is located downstream of the dryer. At least one nipping roller is located downstream of the dryer and upstream of the former. A spreading device is provided between the dryer and the at least one nipping roller that is located upstream of the former and along the conveying path of the first web.
