Visual color correlation improving method for e.g. luggage space cover, involves providing non-symmetrical tolerance area with permissible color variation which is direction-controlled

摘要

The method involves providing a non-symmetrical tolerance area with permissible color variation, which is direction-controlled. Three axes of different length are assigned to the tolerance area. A center of gravity of the tolerance area is displaced against the origin of a coordinate system. The process of coating is changed depending on the estimated color deviation. The color for the coating of a construction unit is changed through tones. A set of coating parameters for the coating of the construction unit is changed. The construction unit is made of polymer material. An independent claim is also included for a construction unit coated with lacquer.
