Method and device for recognizing an object on a surface |
摘要 |
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.
