Development of color matching system for pre-colored wool top blends by optimized Stearns-Noechel model

Being lack of color matching system for pre-colored wool top blends,it is urgently needed to develop a computer-aided system to help colorists find a good recipe to reproduce a target color.An optimized mathematic model that can be used in computer color matching for wool top blends is set up by using the improved Stearns and Noechel.Then the tri-stimulus algorithm principle and arithmetic process for realizing the computer color matching of wool top blends based on the improved model are analyzed,the methods to modifying the error in the matching recipe and control method for the color matching effect are proposed.The experimental results by using this new color-matching system show that the average forecast color difference is 0.614 CIELab units,and it provides recipes quickly and conveniently,demonstrating that this system is suitable for color matching of wool top blends.
