色差公式的发展及其在织物颜色评价中的应用

Development of Color Difference Formula and Its Application in Fabric Color Evaluation

介绍了色差公式在纺织领域内的应用,主要是其在测色配色系统中的发展与应用,包括色差量化、宽容度设定、色牢度评价、同色异谱评价等。分析了各类色差公式的优缺点及纺织行业内颜色评价存在的问题,提出色差公式选用的一般规律。在此基础上,总结了色差公式的研究和发展,介绍了纺织各领域内常被采用的4类色差公式,同时提出了色差公式的发展趋势。分析认为:目前纺织品颜色控制及评价中,用CIEDE2000色差公式比CMC或CIELAB更适合,但还需根据实际情况进行修正。而对于颜色值不是对纺织品直接测色获得的情况下,CIEDE2000并不是最好的选择,可选择如CIE94等色差公式。

This paper introduces the application of color difference formula in textile field,mainly its development and application in colorimetry and color matching system,including quantization of color difference,setting of tolerance level,evaluation of color fastness and metamerism evaluation etc.;analyzes advantages and disadvantages of various color difference formulas and problems of color evaluation in textile industry and puts forward general rules for the selection of color difference formula;summarizes the research and development of color difference formula on this basis,introduces four color difference formulas commonly used in various fields of textile and meanwhile puts forward the development trend of color difference formula.The analysis considers that,in color control and evaluation of textiles currently,it is more appropriate to use CIEDE2000 color difference formula than CMC or CIELAB,but it should be revised according to actual conditions.Under the condition that color value is not obtained by direct colorimetry of textile,CIEDE2000 is not the best choice and CIE94 etc.can be chose.
