Publication number: 20160279925Abstract: A gravure printing press utilizes a printing assembly with a printing forme cylinder that is twice as large in relation to the number of multiple copies which can be printed during one revolution. The printing forme cylinder, in a thrown-on position, forms a printing point with an impression cylinder which is twice as large in relation to the number of multiple copies which can be printed during one revolution. A wiping cylinder, in a thrown-on position, also interacts with the printing forme cylinder. An ink collecting cylinder, in its thrown-on position, interacts with the printing forme cylinder. A plurality of stencil cylinders, in thrown-on positions, interact, one after another, with the ink collecting cylinder on the circumference thereof. Each of the stencil cylinders can be inked by at least one inking unit.
