| Résumé : |
When it comes to color testing, there are many precise instruments, color correction software packages, automated spray machines, etc., in the marketplace. Colorimetry is a science of great importance to the paint industry, especially in meeting the high-quality standards of customers. However, the high scientific level and the precision of the instruments cannot compensate for the challenges presented, because conventional color testing takes place at the very end of the paint production process and requires a great deal of time due to the drying process. In addition, it has become state-of-the-art to correct colors instead of producing them in the required quality in the first run. |
