  1. Objective To study the impact of the ink type of pens on the examining result of the sequence of strokes and stamp impressions by raman imaging.  Method 188 inks of pens including 22 kinds of black ballpoint pens, 62 kinds of blue ballpoint pens, 62 kinds of black gel pens and 42 kinds of blue gel pens were classified based on the different raman spectra, and the sequence of strokes written by those inks and stamp impressions were examined by raman streamline scanning. Result 188 inks were divided into 4 categories and 23 sub-categories. The imaging results of the sequences of strokes made by these 4 categories of inks and the stamp impression were good. Conclusion The ink type of pens has no impact on the examining result of the sequence of strokes and stamp impressions by raman imaging.

Abstract:  raman streamline scanning; ink; sequence of stroke and stamp impression

摘要： 目的 考察在运用拉曼光谱阵列面扫描检验朱墨时序的方法中书写笔油墨种类对检验结果的影响。方法 根据拉曼谱图的不同对搜集的188种书写笔（包括22种黑色圆珠笔，62种蓝色圆珠笔，62种黑色签字笔，42种蓝色签字笔）进行扫描并分类，采用拉曼光谱阵列面扫描技术对书写笔与同一印泥和印油形成的朱墨时序样本进行检验。结果 188种书写笔被分为4大类23小类，4类书写笔与印泥或印油形成的朱墨时序样本都得到了较好的检验结果。结论 在本实验条件下，书写笔油墨种类对拉曼光谱阵列面扫描检验朱墨时序的检验结果没有影响。
