| 摘 要： | 目的建立显微共焦拉曼光谱法区分喷墨打印机打印的彩色图文墨迹的方法。方法利用显微共焦拉曼光谱技术所具有微量、微区、原位分析及非破坏性等特点,对24种常见彩色墨水墨迹分别进行检验。结果品红色墨点墨迹成分归类区分效果最好,其次是黄色墨点,最后是蓝色墨点。结论采用显微共焦拉曼光谱技术对彩色打印墨迹进行不同颜色单点分析可大大提高喷墨打印机厂家型号的识别率,是一种有效的检测手段。

| Abstract: | A microscopic and non-destruction approach for the analysis of inkjet inks is being reported. Microscopic Raman Spectroscope was used to determine if inkier inks from various manufacturers and models of printers could be differentiated and identi- fied. As inkjet printing often involves the use of multiple colors to form an image or text, three color （magenta, yellow and blue） dots on inkjet printings printed with 24 models of ink cartridge （produced by three manufacturers ）were analyzed. The results showed that most of inkjet printings can be differentiated by ink analysis. |
