摘　　要：为给纺织行业在纺织品贸易和质量控制等方面优选色差公式提供参考,研究了3个重要的和1个最新色差公式的色差均匀性,借助国际上色样多、视觉等距性好的汉风色典,利用X-Rite测色仪测试近2万个色样的色度参数,然后分别从向度、彩度、浓度3个方向选取3万多对相邻色样,采用MatLab编程计算4种色差并统计分析其均值、不匀率和性能因子。结果表明:不同方向不同评价指标所得结果不尽相同;在色差均匀性方面,CAM16-UCS最好,CIEDE2000(2∶1∶1)略优于CMC(2∶1),且二者明显优于CIELAB;在色差大小方面由小到大依次为CIEDE2000(2∶1∶1)、CMC(2∶1)、CAM16-UCS、CIELAB。In order to provide a reference for more suitable color difference formulae for textile industry in trade and quality control,the uniformity of 3 main and 1 newest formulas was studied by utilizing Sino Color Book(SCB)with the largest number of internaterial samples(nearly 20000)and good visually equidistance,their chromaticity parameters were measured by the X-Rite spectrophotometer,and then more than 30000 pairs of adjacent color samples in SCB were selected from three directions of hue,chroma and depth,respectively.Their color differences were computed by MatLab programming and their statistic data of average,and CV values and performance factor were analyzed.Results show that different evaluation indexes in different directions exhibit different effect.For the uniformity of the 4 color different formulas:CAM16-UCS is the best,and CIEDE2000(2∶1∶1)is slightly better than CMC(2∶1),and both are obviously better than CIELAB.For the value order of the 4 color differences:CIEDE2000(2∶1∶1)<CMC(2∶1)<CAM16-UCS<CIELAB.
