Beschreibung
Zusammenfassung:	The invention relates to a method of producing color pastes, in which a component comprising colorant particles is dispersed in a binder. In the method of the invention the dispersing operation is controlled by beaming excitational light of a defined wavelength range into a mixture of the component comprising colorant particles and the binder, detecting the light transmitted, reflected and/or scattered by the mixture and determining a sample spectrum, evaluating the sample spectrum and hence determining parameters of the color paste, and monitoring changes in the sample spectrum over time and terminating the dispersing operation when predetermined target parameters are attained.
