1. A processing machine (01) for processing a substrate (02) comprising at least one shaping unit (900), the at least one shaping unit (900) comprising at least one forme cylinder (901) and at least one impression cylinder (902), a processing point (910) for processing a substrate (02) being located between the at least one forme cylinder (901) and the at least one impression cylinder (902), the processing machine (01) comprising at least one control unit (1201) for correcting a processing length (BL) which controls in an open loop and/or a closed loop a speed (v1; v2; ω1; ω2) of the at least one forme cylinder (901) and/or of the at least one impression cylinder (902), the speed (v1; ω1) of the at least one forme cylinder (901) and the speed (v2; ω2) of the at least one impression cylinder (902) having a speed ratio (v1/v2; ω1/ω2) with respect to one another, and the speed ratio (v1/v2; ω1/ω2) being changeable and/or changed at the processing point (910) by means of the control unit (1201) as a function of the processing length (BL) of a substrate (02), characterized in that the speed ratio (v1/v2; ω1/ω2) for correcting the processing length (BL) differs at least once within a full cylinder revolution.
