A rotary offset printing machine, preferably to be used as a proofing machine, has one or more traversing rollers (14a, b) which roll off along their ink applicator roller (10) and whose axial length is only a fraction of the axial length of the ink applicator roller (10) and which are axially displaceable over the entire length of the ink applicator roller between two sheet prints. The sheet supplied to the printing unit of the machine is controllable provided the ink film on the ink applicator roller (10) has an even thickness. A plurality of traversing rollers (14a, b) can be arranged so as to be axially offset relative to one another and distributed over the circumference of the ink applicator roller. During the evening-out of the ink film, the ink applicator roller (10) is preferably raised from the plate cylinder (11). <IMAGE>
