喷墨打印机走纸步进量作为机种特征的实验研究

目的确定一个有助于识别喷墨打印机种的墨迹特征。方法对Epson、HP、Canon和Lexmark四大品牌的65种喷墨打印机的实验输出样本墨迹中重复出现的瑕疵进行分析。这些瑕疵包括：横向漏白条纹、重叠条纹和纵向对接错位等。结果相邻两个瑕疵之间的距离与打印机固有的走纸步进量直接相关。观测得出的走纸步进量既稳定又反映特定机种。结论将走纸步进量作为一个喷墨打印机种特征来利用具有较强的有效性和可行性。

Experimental Study on Step Increment of Paper Feed for Classification of Inkjet Printers

Objective To establish the step increment of paper feed as a valuable characteristic for classification of inkier printers. Method 65 different models of inkier printers of Epson, Hewlett Packard, Canon and Lexmark were experimentally investigated. Repeated defects on printed paper, such as horizontal white line, overlap banding and vertical misaligning, were analyzed and measured. Results The distance between two adjacent defects was related directly to the step increment of paper feed of inkjet printers. The step increment of paper feed was stable and indicated a specific type of printers. Conclusion The step increment of paper feed could be used as a valid characteristic to classify inkjet printers.
