In an inking unit for a printing press having an ink duct with an ink-duct roller revolvable at a given speed therein, a transfer roller in rolling contact with the ink-duct roller, the transfer roller having an outer cylindrical surface formed with a plurality of helical ridges thereon, and a distributor roller revolvable at press speed greater than the given speed of the ink-duct roller, the transfer roller being rollable on the distributor roller for transporting ink film from the ink-duct roller farther into the inking unit, the improvement there including mutually meshing gear means carried by the transfer roller and the distributor roller, the transfer roller being drivable by the distributor roller via the gear means, and means for applying contact pressure of such magnitude between the transfer roller and the distributor roller during rolling of the transfer roller on the distributor roller that there is continuous contact between the surface of the distributor roller and the surface of the transfer roller located between the ridges, the ridges being in relatively low-pressure contact with the ink-duct roller revolving more slowly than the distributor roller.
