摘要
A method is disclosed that relates to maintaining or improving the end quality of the visual color imprint of multiple-colored patterned surfaces. These surfaces cannot be measured using the decorations that are manufactured by printing processes, the so-called primary decoration, because subsequent processes change the color imprint further resulting in the so-called secondary color imprint. According to the invention, prediction rules are determined based on samples from the primary and secondary decorations during a learning phase to establish from n-channel images of samples of the primary decoration color imprint characteristics and convert those to such characteristics for the secondary decoration; and/or to establish from n-channel images of samples of the primary decoration images of the secondary decoration and to calculate color imprint characteristics. Color imprint characteristics are extracted and converted with the aid of the prediction rules to the color imprint characteristics of the secondary decoration, and applied.
