A computer controlled sheet-fed offset printing machine is described which includes an Interpreter-program for obtaining an image of the signal-state of specified interfaces of the many interfaces that are needed for the operation of the computerized printing press. The Interpreter-program has access to a reserved region of memory for storing and manipulating, if desired, the image of the signal-state. Furthermore, the Interpreter-program has very limited and defined access to the inputs and resources used by the control programs used to operate the computerized printing press. This ensures that the control programs can execute in real-time unaffected by the execution of the Interpreter-program while data is acquired by the Interpreter-program while the computerized printing press is in operation. The Interpreter-program can execute diagnostic routines and provide data for detecting and correcting errors that are otherwise hard to localize in a complex system with complex software.

A cylinder for a printing press is adjusted away from a printing stock web or an adjacent cylinder by rotation of an eccentric element. The change in position caused by the movement of the eccentric element is compensated by an additional rotating movement superposed on the rotating movement of the cylinder such that the outer surface of the cylinder has no relative velocity relative to the adjacent cylinder or the printing stock web. Compensation is carried out by a regulating circuit to which is supplied the actual rotational angle of the cylinder with respect to the eccentric element and the actual rotational angle of the eccentric element with respect to the side wall or an angular function derived therefrom.
