A contact pressure between ink-carrying cylinders of a printing machine are automatically adjusted. At least one ink-carrying cylinder can be disengaged from the ink-receiving cylinder. A width measuring device measures a width of a contact strip transferred from the ink-carrying cylinder to the ink-receiving cylinder. The measuring device may be aimed at the ink-receiving cylinder or at a product issuing from the last printing unit. A control or regulating device compares the signals which represent the width of the contact strip and, if necessary, adjusts the contact pressure. The adjustment may be parallel, i.e. the contact pressure is increased or decreased uniformly along the cylinder axis, or is may be one-sided, if the contact strip image is non-uniform or wedge-shaped.
