Process for printing sheets in face and reverse printing as well as face printing

摘要

The sheets are automatically run twice through the printing machine in a method for first and second form printing. The first side of the sheets is printed with one or several colors during the first imposition. The sheets thus printed are then stored in a buffer device (11) inside the printing machine. The buffered sheets are rotated 180 DEG on the plane covered thereby and printed on the second side with one or several colors during a second imposition. Finally, the sheets printed on both sides are fed to a final storage device.
