RECIPE CALCULATION METHOD FOR MATT COLOUR SHADES

摘要

The present invention provides a colour recipe calculation method for matt finished, solid colour shades, by means of which it is possible to determine the proportion of matting agents in a colour recipe in a manner decoupled fr om the actual calculation of the recipe and is based on a conventional spectrophotometric characterization of a matt sample using a standardised 45~/0~ measurement geometry along with an established gloss measurement, or alternatively using a spectrophotometer equipped with a d/8~ measurement geometry and analyzing readings taken with the specular component included a nd excluded.
