以素面镭射纸为例，通过实验，阐述了结合相对反差和色彩反差来确定印刷最佳实地密度的方法。
The method was illustrated by experiment on plain laser paper to combine relative contrast and color contrast to obtain optimum solid density of printing.
UCR有利于色彩密度和色度的良好再现，但会损失图像的反差和灰平衡效应。
UCR is conducive to the reproduction of density and saturation, but likely to lose contrast and gray balance of image.
