采用激光拉曼光谱技术对10种印文色料进行了测试研究,根据实验所得印文色料的测量数据,将测试的印文色料分为6类。实验发现,国内与国外生产的印文色料成分有所不同,国内同一厂家生产的不同型号的印文色料成分有所不同,不同厂家生产的印文色料成分也有相同,拉曼光谱技术可有效地检测出主要成分为金光红或大红粉的印文色料。结合实验,采用控制变量的方法,分析了样品自身、实验环境、实验条件、参数设定等因素对实验测量数据的影响。

10 kinds of pigment were tested by laser Raman spectroscopy,and we classify the obtained experimental data into six categories though Raman peaks.Through the experiment,it is found that the pigment producted by domestic and foreign are different,the same domestic manufacturers of different types of seal pigment vary from each other,different manufacturer’s pigment components have the same.Raman spectroscopy can effectively detect pigment material seals which contain big red or bronze red.The setting of various parameters has great influence on the experimental data.Using the method of control variables,we analysis the influence of the sample itself,the experimental environment,experimental conditions,parameter settings and other factors.
