Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a printer that can know and react to variations in roll motions.SOLUTION: A web printing press includes: at least one printing unit printing images on a web; at least one press component in direct contact with the web; a cutting device for cutting the web into sheets; a controller transmitting a virtual master signal to the at least one printing unit and at least one press component; a sensor sensing at least one press component or directly senses the web downstream of the at least one print unit and generates a sensor signal; and a processor receiving the sensor signal and the virtual master signal, the processor transmits a modified virtual master signal to the cutting device as a function of the received sensor signal.
