Abstract
A web printing press is provided. The 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 and a controller transmitting a virtual master signal to the at least one printing unit and at least one press component. A sensor senses the at least one press component or directly senses the web downstream of the at least one print unit and generates a sensor signal. A processor receives 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. Methods are also provided.
Claims20
A web printing press comprising:
- 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 the at least one press component or directly sensing the web downstream of the at least one print unit and generating a sensor signal;
- and
- a processor receiving the sensor signal and the virtual master signal, the processor transmitting a modified virtual master signal to the cutting device as a function of the received sensor signal.
A method for printing a web comprising the steps of:
- printing a web using a printing unit receiving a virtual master signal;
- sensing a characteristic of a press component in direct contact with the web or directly sensing a characteristic of the web downstream of the printing unit;
- and
- modifying the virtual master signal for a further press component downstream of the print unit and the press component as a function of the sensed characteristic.
A method for printing a web comprising the steps of:
- printing a web using a printing unit receiving a virtual master signal;
- acting on the printed web with at least one press component receiving the virtual master signal;
- determining a deviation between the virtual master signal and an actual characteristic of the at least one press component;
- and
- modifying the virtual master signal for a further press component downstream of the at least one press component as a function of the deviation.
