Abstract
The invention relates to a variable printing machine which is embodied in the form of at least two offset printing apparatus (1) and comprises a frame bearing an opposite cylinder against which a blanket (11) to be printed is pressed by a blanket drum. Printing ink is supplied to a printing cylinder which contacts the blanket drum by means of inking rollers. The inventive printing machine is characterized in the following: the opposite cylinder of each apparatus (1) is devoid of all rotatable transmissions; a levelling between two adjacent units which print one and the same blanket face (11) is embodied in such a way that said blanket is in contact with the blanket drums only.
