Abstract

Recognizing a print substrate in the vicinity of a sensor within a printing machine, whereby a change in the capacitance of the system formed by the sensor and a surface of an area in which a print substrate should be recognized, is recognized by the sensor. In this way, print substrates can already be identified on the basis of a dielectric constant that is different from that of air.

Claims (6)

1. A device for recognizing a print substrate in the vicinity of a sensor ( 11 ) within a printing machine, including a rubber blanket drum, comprising: at least one electric sensor ( 11 ) in the vicinity of a surface area of said rubber blanket drum, upon which a print substrate should be recognized, and a circuit connected to said at least one electric sensor ( 11 ), said circuit kept ready so as to recognize a change in capacitance due to the print substrate being in the vicinity of said at least one electric sensor.

2. The device according to claim 1 , wherein said circuit includes a voltage applied between the sensor ( 11 ) and the surface of an area of said rubber blanket drum.

3. The device according to claim 1 , wherein a current flow is measured by said sensor ( 11 ).

4. The device according to claim 1 , wherein said sensor ( 11 ) is a charged wire in the vicinity of the surface of an area of said rubber blanket drum.

5. The device according to claim 1 , wherein at least one part of said electric sensor ( 11 ) has an electric voltage that deviates from that of the surface of the area of said rubber blanket drum.

6. The device according to claim 1 , wherein said sensor ( 11 ) is a charging wire.
