摘　　要：本文以印油(印泥)为实验对象,共收集不同品牌印油(印泥)36种。使用显微分光光度计检测样本的色度数据并计算出色差ΔΕ。根据相关国家标准规定,以ΔΕ等于6 NBS为阈值,判断ΔΕ小于6为同种印油(印泥),判断ΔΕ大于等于6的为不同种印油(印泥)。研究结果表明,ΔΕ小于6,其色差符合率为87.79%;ΔΕ大于等于6,其色差区分率为90.16%。Thirty-six brands of stamp collected from market were studied by using miscroscopic spectrophotometry （MSP）. The MSP were used for chromatic aberration （AE） calculation to distinguish the chromaticity of the samples. According to some relevant national standard, selecting AE equal to 6 as threshold value, judging as same type of stamps which AE is less than 6,. Judging stamps that AE is equal or greater than 6 as different type of stamps. The study＇s result show that coincidence rate which AE is less than 6 is 87.79 %. The distinguish rate, AE is equal or greater than 6, is 90.16 %.
