基于CCD的3种喷墨印刷品均匀度检测模型的比较

Comparison of Three Inkjet Print's Uniformity Detection Models Based on CCD

在分析ISO 13660规定的2种均匀度检测模型的计算原理的基础上,另外介绍了一种将人眼视觉系统考虑在内的检测模型的计算原理和过程。通过设计实验,分别利用这3种检测模型对CCD仪器获取的打印样稿进行了均匀度检测,然后将检测结果与人眼主观评价相结合,分析比较了这3种均匀度检测模型与人眼视觉的相符程度,结果表明:将人眼视觉考虑在内的IM Mottle模型更能反映印品的均匀程度;ISO 13660规定的色斑属性对印品均匀度的影响比颗粒度属性的影响更大。

Based on the analysis of two uniformity detection models stated by ISO13660, a new model which took human visual system into consideration was introduced. These models were used to detect the uniformity of print acquired by CCD device through experiment, and their consistent with human visual evaluation was compared. The results showed that IM Mottle model considering human vision can reflect the uniformity of print better; mottle stated by ISO13660 has greater impact on the uniformity of print than graininess.
