Red seal inks from Korea (6), Japan (1) and China (6) were studied to investigate the feasibility of micro-attenuated total reflectance (ATR) FTIR spectroscopy as a tool in the forensic study of questioned documents involving seal inks. The technique was able to differentiate red seal inks of similar colors and different manufacturers. Blind testing has shown that micro-ATR FTIR can identify the origin of the red seal inks with accuracy. Data gathered were converted to a database for future reference. Also, the technique was also successful in determining the sequence of heterogeneous line intersection from a personal seal and a ballpoint pen. The results show that micro-ATR FTIR can be a valuable non-destructive tool for the objective analysis of questioned documents involving different red seal inks.
研究了来自韩国（6 个）、日本（1 个）和中国（6 个）的红色印章油墨，以探讨微衰减全反射（ATR）FTIR 光谱作为一种工具在涉及印章油墨的可疑文件的法医学研究中的可行性。该技术能够区分颜色相似但制造商不同的红色印章油墨。盲测表明，微 ATR FTIR 可以准确识别红色印章油墨的来源。收集的数据被转换为数据库，以备将来参考。此外，该技术还成功地确定了个人印章和圆珠笔的异质线交点的顺序。结果表明，微 ATR FTIR 可以成为一种有价值的非破坏性工具，用于对涉及不同红色印章油墨的可疑文件进行客观分析。
