  • Patent number: 11391631
    Abstract: 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.

  • Publication number: 20220146313
    Abstract: Described herein is an analytical system (100) 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 (103) with a multiplicity of sensors, an administrative unit (105) with at least one processor, and an output unit (107). 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.

  • Patent number: 10996110
    Abstract: A heuristic process for color formula calculation of pigmented shades matched to a target shade, comprising the steps of i) using suitable calibration scales to compile an effect matrix for each of the ingredients included in a coloring system, ii) determining the optical materials parameters of the target shade, iii) selecting a suitable starting formula, iv) determining the color difference between the starting formula and the target shade, v) calculating a first matched color formula while taking account of the effect matrices, vi) repeating steps iv) and v) until an acceptable remaining color difference is reached, wherein the effect matrices are continually updated with shade-relevant information during ongoing operation, achieves an improvement on the existing processes for shade formula calculation, not only in terms of reducing the number of tinting steps needed but also in terms of minimizing the remaining color difference.

  • Publication number: 20110058173
    Abstract: A method of preparing effect pigment color formulas matched to a color original, comprising the steps of (a) producing a calibration series for each pigment included in the coloring system of an effect pigment color original, (b) experimentally determining the reflectances R? of the color original and of the calibration series, (c) calculating the optical parameters of the color original and of the constituents of the coloring system, (d) selecting a suitable starting formula, (e) determining the residual color difference between the starting formula and the color original, (f) producing a first matched color formula, (g) and repeating steps (e) and (f) until the residual color difference between the matched color formula and the color original is acceptable, which involves (i) transforming the reflectances R? of the color original and of the calibration series by means of a suitable mathematical function such that all of the transformed reflectances R?? lie between 0 and 1, and (ii) calculating the optical
