Abstract
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.degree. to 10.degree. and optimally by an angle of 5.degree..
