Abstract

A printing press has a plurality of in-line printing units in which substrates are transported along a rectilinear transport path. The printing units include several recto printing units and several verso printing units disposed along the transport path. A transport system, which transports the substrates through the printing units along the straight transport path, includes a first transport apparatus through the recto printing units, and a second transport apparatus through the verso printing units. A feeder assembly feeds the substrates to be printed from a feeder pile to the transport system. The feed by the feeder also follows a straight path which is coplanar with the path through the printing units. It is thus possible to print not only bendable substrates, but also rigid and stiff substrates such as carton, plastic, sheet metal, glass, and the like. The system further includes a turning apparatus for turning the substrates between the recto printing units and the verso printing units.
