Abstract
An inking unit includes a first smoothing roller, an ink feed unit constructed as an ink droplet generator for applying a metered quantity of ink to the first smoothing roller, by one of an indirect and a direct path, respectively, the indirect path being via at least one additional roller interposing the ink feed unit and the first smoothing roller, and the direct path being directly to the first smoothing roller, and further including a second smoothing roller operatively connected to the first smoothing roller for distributing the application of ink, each of the first and the second smoothing rollers having a hard smoothing surface with a hardness of one of at least 80 Shore A and at least 30 Shore D, respectively, for forming a uniform film of ink; and an offset printing machine including the inking unit.
