网点增大和相对反差的控制原理与方法研究

Study on Controlling Principles and Methods of Halftone Dot Accretion and Relative Contrast Control

网点增大和相对反差是基于密度的印刷质量控制体系中两个重要的控制参数。文章主要论述了网点增大和相对反差的控制原理,详细解释了布鲁纳尔测控条检测网点增大的方法以及相对反差的测控方法。

Both halftone dot accretion and relative contrast are the important parameters of printing quality control system based on density. This essay discusses the controlling principle of halftone dot accretion and relative contrast, and explains in detail using Brunner controlling bar to measure and control halftone dot accretion and relative contrast.
