Claim:
A method for producing pharmaceuticals or parts of pharmaceuticals or food supplements or parts thereof, comprising: preparing a sprayable solution, suspension or dispersion of a film-forming coating agent in a liquid; preparing a separate sprayable solution, suspension or dispersion of a pigment in a liquid; simultaneously spraying by spray application onto a substrate of the pharmaceuticals or parts of pharmaceuticals or food supplements or parts thereof with the solution, suspension or dispersion of a film-forming coating agent and the solution, suspension or dispersion of a pigment; thereby coating the substrate with the film-forming coating agent comprising the pigment; evaporating the liquid of each solution, suspension or dispersion; forming a uniformly pigmented film coating on the pharmaceuticals or parts of pharmaceuticals or food supplements or parts thereof; wherein the film-forming coating agent is a (meth)acrylate copolymer having cationic or anionic groups, the sprayable solution, suspension or dispersion of a film-forming coating agent and the sprayable solution, suspension or dispersion of a pigment are incompatible with respect to destabilization of the dispersion, coagulation, signs of inhomogeneity or similarly unwanted effects if combined before spraying, and the simultaneously spraying by spray application comprises one or more spray devices which separately spray liquids, singly or together, and separate spray beams of the one or more spray devices overlap.
