Verfahren zur Abscheidung von farbigen Schichten auf Substrate und Vorrichtung zur Durchfuehrung des Verfahrens

The invention relates to a process for the deposition of coloured layers on substrates, in which light is injected from an external light source into the recipients and guided onto the substrate, the transmitted and/or reflected light for the recipients is sent to a detector during the layer build-up, the detector is linked to a computer where the intensity values are converted into colour actual values and the computer controls the evaporation units as a factor of the colour actual value from a colour reference value entered in the computer until said reference value is reached.
