Abstract

An offset inking unit includes a distributor roll having a first roll train that communicates via a first branch roll with an ink transport roll engaged, as viewed in the direction of rotation of the plate cylinder, by two front inking rolls and having a second roll train connected in parallel to the first roll train that communicates via a second branch roll with a spreader roll which, as viewed in the direction of rotation of the plate cylinder, is engaged at least by the first inking roll of the two front inking rolls. Also as viewed in the direction of rotation of the plate cylinder, the second inking roll of the two front inking rolls communicates at least with another rear inking roll via another ink transport roll. Damping is optionally effected directly on the printing plate or on a front inking roll.
