ABSTRACT:
In the sheet-by-sheet printing process, a sheet is printed during its passage in the nip zone between a printing cylinder, which comprises on its periphery a rubber element, and an impression cylinder. The ink is supplied to the printing cylinder by an ink supply cylinder. In order to reduce the deformations of the printing dots, the ratios of the peripheral linear speeds of the ink supply cylinder and of the impression cylinder with respect to the peripheral linear speed of the rubber element of the printing cylinder are adjusted to values in the range of 1.004 to 1.05.
