本研文鉴别不同品牌、型号彩色激光打印机打印文件提供一种无损、便捷的检验方法。利用显微激光拉曼光谱仪检验彩色激光打印机打印文件墨迹,对四种颜色墨迹的拉曼光谱图进行比较区分,发现不同品牌、型号彩色激光打印机打印文件的四种颜色墨迹的拉曼光谱不同,因而可以利用显微激光拉曼光谱技术区分不同品牌、型号的彩色激光打印机打印文件。

This work provide a non-destructive,convenient and effective testing method to differentiate documents printed by different color laser printers. The ink marks on the documents printed by color laser printers are tested by the Micro-Raman spectroscopy,and the four different color ink marks’ Raman spectra are compared and differentiated. The Raman spectra of the documents are different and can be classified. The Raman spectroscopic technique can distinguish the documents printed by different brands and models’ color laser printers.
