Printing unit for blanket-to-blanket printing

摘要

The present invention relates to a printing unit for blanket-to-blanket printing. The printing unit includes two printing couples positioned one on top of the other. Each printing couple includes a form cylinder and a transfer cylinder. The transfer cylinders each carry a gap-free blanket. A horizontal web passes between the transfer cylinders of the two printing couples. In order to achieve good print quality with an advantageous web path, a plane connecting the centers of the transfer cylinders is inclined from a plane extending perpendicular to the web and passing through the center of one of the transfer cylinders by an angle ( alpha ) in the range from 0 DEG to 10 DEG and optimally by an angle of 5 DEG .
