ABSTRACT:
An offset printing machine comprises a plate cylinder and a blanket cylinder respectively carrying roller tracks rolling on one another and determining the center distance between the two cylinders. At least one inking roller with a supple peripheral layer, fed with ink from an inking assembly, is carried by levers pivoted about the axis of an inking cylinder and it carries roller tracks in contact with those of the plate cylinder. The shaft of the inking roller is mounted in its roller tracks via eccentric hubs locked on the shaft and pivoting in the roller tracks via bearings, and one end of this shaft is fast with a gear coupled to a control shaft for adjusting the pressure contact of the inking roller upon the plate cylinder.
