Process and device for recognition of substrate stock by means of light-sensitive sensors |
摘要 |
Recognizing a substrate stock by light-sensitive sensors inside a printing unit, by a sensor that can recognize several ranges of light wavelengths. By separate recognition of various ranges of light wavelengths, a substrate stock is recognized whenever the total reflection capabilities of surface and substrate stock determined across all light wavelengths coincide.
