Abstract

A web offset press includes several printing units through which a web passes essentially in a horizontal direction. The printed web then passes to at least one first folding unit. Each of the printing units has at least one plate cylinder and one transfer cylinder which interacts with the web being printed. An effective plate width of the plate cylinder corresponds to the print image of at least eight upright or prone printed pages in a BIN 4A format. The printed web is slit longitudinally into a plurality of web strands: A first number of these web strands are supplied to the first folding apparatus. At the same time, a second number of web strands, produced by the slitting of the same web, are supplied to a second folding apparatus for further processing.
