Described herein is an analytical system () for assessing and predicting a performance factor of at least one coating on at least one object with a multiplicity of subunits. The analytical system includes a sensor arrangement () with a multiplicity of sensors, an administrative unit () with at least one processor, and an output unit (). The sensor arrangement is configured to subject the at least one object coated with at least one respective coating to colorimetric measurement by means of the multiplicity of sensors and to provide corresponding measurement data to the administrative unit. The administrative unit is configured to determine respective colorimetric deviations of the at least one coating relative to a corresponding color reference for a multiplicity of subunits of the at least one object, and to output these deviations on the output unit.

Analysis system and method for evaluating and predicting a quality of a coating

Disclosed is a process for determining a plurality of color quality indicators for controlling the color of a coating. Colorimetric coordinates of a color reference and the coating are ascertained for a plurality of coated surface elements using a spectrophotometer at a number of measurement geometries and a number of light sources. For each measurement geometry and each light source, color differences are calculated from the colorimetric coordinates of the color reference and the coating of the plurality of coated surface elements. The respective colorimetric coordinates are normalized with one weighting factor. Each of the plurality of color quality indicators is determined by means of a mapping, of functional values onto a scale value of a predetermined scale. The functional values are determined in each case for the number of measurement geometries and the number of light sources by means of a mathematical relationship.
