彩色印刷中四色彩印定义

彩色印刷过程中,对色彩的再现实质上是颜色的“分解”和“合成”过程。任何一幅原稿,不管其画面上的颜色多么复杂、层次多么丰富,从颜色科学上来讲,画面上各点的颜色都是三原色光以一定比例的组合。颜色的分解就是利用 R 、 G 、 B 三滤色片将画面各点中的颜色从混合状态中分离出来,并形成各自在画面分布情况的单色影像。
In the process of color printing, the color reproduction is essentially "decomposition" and "synthesis" of the color. Any piece of the original, no matter how complex, the picture color level how abundant color science from speaking, the picture of each point on the color is combined with a certain percentage of primary colors. The color of the decomposition is to separate the screen color from the mixed state by using R, G, B three filters, and the formation of their distribution in monochrome image picture.

颜色的合成则是用分解得到的三种单色影像制成印版,再通过印刷分别把黄、品红、青三色油墨逐次叠印到承印物上,再现原稿上的彩色图像。

The color of the synthesis is three kinds of monochromatic images obtained by printing plates, printing the yellow and magenta and cyan ink overprint gradually to the substrate, the original color image reproduction.
在这两个过程中,自始自终都离不开光和色的作用。在平版印刷中,为了再现原稿上的色彩,首先要利用照相分色、电子分色或扫描仪分色的方法对彩色原稿上的色彩进行分解。原稿上的彩色图像经过 R 、 G 、 B 三滤色片,被分解成青、品红、黄三张分色阴图片。下面我们将以黄( Y )、品红( M )、青( C )、红( R )、绿( G )、蓝( B )、白( W )、黑( K )八个色块代表原稿,并按胶印印刷工艺来说明印刷过程中颜色的分解与合成。
In these two processes, all along all depends on the role and color. In lithography, in order to reproduce the original color, first using the method of photographic color separation, color or electronic color scanner is used to decompose the original color color. The original color image by R, G, B three color is decomposed into cyan, magenta, color Huang Sanzhang Yin pictures. Here we will be the yellow (Y), Pin Hong (M), green (C), red (R), green (G) and blue (B) and white (W), black (K) eight colors on behalf of the manuscript, and according to the offset printing technology to illustrate the decomposition and synthesis of color printing process.
