摘要
目的探讨利用彩色打印图像上的半色调结构特征进行种类鉴别的方法。方法通过对上百种彩色打印设备输出的实验样本进行放大观察和形态学特征比较,详细描述了半色调结构特征。结果发现半色调结构特征反映打印设备硬件和软件方面的固有特征,具有特殊性和稳定性,综合其构成的各个方面可以作为彩色打印设备机种鉴别的一个重要依据。
This paper discusses halftone structures shaped by the techniques of colour printing. The authors have studied the outputs of over a hundred of the colour printers, and find out this kind of characteristics have particularity and stability. Questioned document examiners should use them as one of class characteristics of colour printers.
