摘　　要：目的探索各类喷墨打印种属特征的价值与应用。方法通过研究喷嘴排列、喷头纵长、喷墨技术以及字车运行规律等种属特征实现喷墨打印机的种属认定。结果除佳能与惠普品牌喷墨打印机的喷嘴排列、喷墨技术特征相近,常用喷墨打印机的喷头纵长不一以外,其余各品牌的喷墨打印种属特征之间差异显著。结论依据上述各喷墨打印种属特征,可实现特定打印条件下喷墨打印文件的机具种属认定。Objective To explore the value and applicability of category characteristics from various inkjet printers.Methods Through comparative analysis into the nozzle arrangement plus longitudinal lengths,the ink-jetting manners,theoperating rules of printing carriage and other items necessary to enclose,the category identification of inkjet printer wascarried out.Results Similar nozzle arrangement and ink-jetting manners were found from canon and HP inkjet printer.Commonly-used inkjet printers have discrepant nozzle’s longitudinal lengths.For the rest inkjet printers tested here,there aredistinctive difference of category characteristics among them.Conclusions According to the category characteristics of inkjetprinters investigated in this paper,inkjet printers can be identified with some of their characteristics under certain conditions.
