Abstract
To permit both circumferential as well as axial register adjustment of three printing couples (1, 2, 3), in which the respective cylinders of the printing couples are interconnected by spiral gears, two of the blanket cylinders (4, 8) are axially shiftable. The changes in circumferential register, upon changing of lateral register--due to the spiral gears--are compensated by position motor controllers (34, 44) which may include a microprocessor (50), automatically. Lateral register is set in a predetermined sequence by the respective cylinders, in accordance with the coupling of one of the plate cylinders (e.g. 5) with a printing machine main drive pinion (68).
