Zusammenfassung:	PCT No. PCT/EP97/00555 Sec. 371 Date Dec. 19, 1997 Sec. 102(e) Date Dec. 19, 1997 PCT Filed Feb. 7, 1997 PCT Pub. No. WO97/30342 PCT Pub. Date Aug. 21, 1997A method of determining the visual effect of lacquer coatings in which one, two or more lacquer coatings are applied to the surface of a flat substrate and are dried or hardened, wherein one or two of the lacquer coats are applied with a coat thickness gradient, and one or more surface properties which influence the visual impression are subsequently each measured on the lacquered surface thus obtained, at measuring points distributed over the surface, by means of one or more optical methods of measurement, and the respective thickness of the lacquer coat(s) applied in the form of a gradient is also measured, as well as an apparatus for carrying out the method.
