摘要
采用傅立叶变换红外光谱法对8个厂家的16种型号的激光打印机墨粉进行检测。研究结果表明,根据红外吸收光谱图中在特征频率范围内吸收的差异可以将这16种型号的墨粉分为五大类,根据指纹区吸收峰的差异可以对同一类别中的不同墨粉进行进一步的区分鉴别。该研究对激光打印机形成的文件检验具有现实意义。
Sixteen kinds of laser printer toners from eight factoraries were measured and analysed by fourier transform infrared spectroscopy （FTIR）.Results showed thatthese toners could be divided intofive categories,according to their characteristics infrared absorption,and toners in the same category could be further distinguished by their adsorption in the fingerprint frequency area.This study could be very helpful for identification of documents produced by laser printer.
