The colorimetric evaluation of paints and coatings is usually done by applying and drying the material with subsequent manual measurement. This "dry" process takes up to several hours and may delay the release of batches. In addition, in the development series tests can be carried out only with great effort. Research has also shown that the LCM method is much more reproducible than "dry" processes, because fewer machining processes are required and the measurement is semi-automatic - and thus without direct user influence.
