Abstract
Wood dyeing requires a non-subjective, repeatable method for determining the color testing and matching. Previously published method used human visual perception to determine the percent of dyestuffs. In this study, computer color matching technique was applied into the dyeing of fast growing wood for the imitation of precious wood species. The process includes measuring the color of wood samples, determining dyeset, preparing and measuring basic color samples, establishing a basic database, calculating and correcting recipes. The recipe of black walnut provided by the system was as follows: acid yellow 2G 0.19%, acid green 0.59%, acid red B 0.29%, with the chromatic difference 0.12%. It could be concluded that dyeing with computer color matching technique allows for a faster, less subjective and easily repeatable procedure that is superior to simple human visual perception.
