摘　　要：阐述了彩涂板同色异谱的概念,分析了造成彩涂板同色异谱的本质原因和生产工艺原因。提出了彩涂板同色异谱评价的3类方法:样板目视法、光谱反射率曲线匹配法和同色异谱指数法。进一步分析了色差仪型号、色差计算公式和标准光源对的选择对彩涂板同色异谱指数测定结果的影响。The concept of metamerism in color-coated plates was presented,and the essential reasons and product manufacturing reasons that contribute to this phenomenon were discussed.Three methods for evaluating the metamerism of the color-coated plates were proposed:the template visual method,the spectral reflectance curve matching method,and the metamerism index method.Additionally,the impact of color difference meters,the calculation formula of color difference and the selection of standard light source pair on the measurement results of the metamerism index in color-coated plates were further analyzed.
