| 摘 要： | 目的运用激光显微共聚焦拉曼光谱仪对打印墨水的墨迹样品进行检验。方法采用514nm激发波长,测得EPSON、HP、CANON等3个品牌21种型号墨迹样品的拉曼光谱。结果根据拉曼峰位的异同,可将21种型号墨迹样品分为8大类。结论该方法可以快速区分常见不同种类打印墨水墨迹,为印刷文件的检验鉴定提供方法参考。

| Abstract: | Objective In this study, Micro Raman Spectroscopy was used to analysis printing inkblots. Raman spectra of 3 brands, 21 models printing inkblots were recorded with exciting of 514nm laser. According to the characteristic peaks of different Raman spectra, we can quickly distinguish different kinds of printing inkblots. It provides one reference method for printing document examination. |
