| 摘 要： | 设计了用于图像复制的色标图原稿,对该原稿分别进行GCR与UCR分色后进行输出。分析了不同分色方式下图像密度、色彩饱和度及中性灰的复制特点,比较了不同类型黑版对于阶调层次、色彩及灰平衡的适用性。结果表明:GCR更适合处理暗调图像,有助于改善图像灰平衡,但会损失色彩密度及饱和度;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。

| Abstract: | Color bar original for image reproduction was designed and printed respectively after GCR and UCR color separation.The reproduction feature of different color separation methods was analyzed from density,saturation and neutral grey.The applicability of different type black plates was compared on tone,color and gray balance.The result showed that GCR is more suitable for processing dark tone image,and is favorable to gray balance of image,but likely to lose density and saturation of color;UCR is conducive to... |
