Abstract
To permit easy change-over between double-prime, double-verso (2/2) printing on a substrate web (5) and double-prime, single-verso (2/1) printing, the cylinders are arranged in printing couples so that first and second blanket cylinders (1, 2) are in printing engagement with each other, with the web (5) therebetween and printing couples including blanket cylinders (3, 4) independently of the blanket cylinders (1, 2) are in engagement with each other, with the web therebetween. One (3) of the blanket cylinders of the printing couples is eccentrically shiftable from engagement with the associated blanket cylinder into engagement with another blanket cylinder (2) so that said other blanket cylinder will function as an impression cylinder for one prime image, and as a printing cylinder for the verso image, while, at the same time, another prime image is being applied thereagainst by the shifted blanket cylinder (3). The systems can be multiplied, preferably staggered vertically, with the substrate in form of a web being guided therebetween. The system permits complete disengagement of the printing couple prior to shifting of the shiftable blanket cylinder, and thus avoids smearing of freshly printed subject matter.
