Abstract

A rotary printing press is usable for producing a newspaper product in tabloid format. The printing press has at least one printing unit which is configured so that it prints a web with printed pages in a horizontal tabloid format. A part web, which is formed by slitting a web, is provided with a fold by a plough folder and that is arranged in the path of travel of the web. The web is folded with a first edge region, which is printed with a narrow printed image section, as a folded portion, along a first folding line by the plough folder. A fold former is arranged after the plough folder. The part web is printed with only one horizontal page in tabloid format and is also printed with a narrow printed section on an adjacent edge region. The part web and the fold former are arranged in the partial web travel direction so that the part web, which is folded along one side by the plough folder, runs into the folding former offset. The center of the partial web is not aligned with the former tip but instead is offset with respect to that former tip.
