Abstract
The invention relates to a sheet-fed rotary printing press for multi-color printing with an in-line arrangement of the printing units. Each printing unit comprises a plate cylinder, a blanket cylinder and an impression cylinder, all of a single diameter, as well as three sheet-transfer drums. The sheet-transfer drums of single diameter are provided for printing jobs using a one-sided multi-color printing process. On the other hand, the design for recto-and-verso printing is provided with a storage drum and a turning drum, with the storage drum being of double diameter. Depending on the job structure, the printing press according to the invention can later be converted at the printing shop from one design to the other.
