Abstract
In the case of a short inking unit with at least one transfer roll in the form of a pitted roll a compact design is made possible together with a reliable and accurate inking effect by the feature that there are at least two doctor blades mutually offset from each other in the peripheral direction of the pitted roll. Both the doctor blades have a negative angle of engagement with the periphery of the roll and delimit an ink chamber in the circumferential direction while the ends of this chamber are shut off by cheekpieces. At the walls of the ink chamber there is at least one supply port to be connected in a pressure-tight manner with an ink supply and at least one overflow port.
