Abstract: A printing machine having an inking unit which prevents overinking of the printing cylinder upon increases in printing speed, such as during start-up of a printing operation. The inking unit includes an ink supply, two roll trains each comprising a plurality of inking rolls for communicating ink from the ink supply to a plurality of ink applicator rolls associated with the printing cylinder, with at least one inking roll in each roll train being displaceable in phase with an increase in printing speed for interrupting the respective roll train and preventing excessive ink application to the printing cylinder.
