Abstract

A method and an apparatus control a printing press having a plurality of printing units, a plurality of cylinders which are coupled mechanically to one another and a control computer for controlling at least one drive motor which drives the mechanically coupled cylinders. A torsion model is stored in the machine computer for describing the torsion state of the cylinders in the printing press which are rotatably coupled mechanically to one another, as a function of at least one measurable operating parameter or at least one variable of the printing press which is known to the machine computer. A control of the printing press is performed by the control computer on the basis of the values which are calculated by the torsion model.
