Sheet-fed offset printing press and method of two-sided multi-color printing

摘要

A sheet-fed offset printing press prints multiple colors on both sides of sheets, preferably on sheets of paper. A first row of in-line printing units print a first side of the sheet, before the sheets are turned in a reversing device, which is followed by a second row of in-line printing units for printing the other side of the sheets. The second row of in-line printing units is followed by one or more varnishing units that are arranged in such a way or include varnishing blanket cylinders that are arranged in such a way that the front sides and the back sides of the passing sheets are varnished.
