彩色印刷分色工艺制作原理
作者:admin 来源:http://www.sdhzyw.com 发布时间:2016-9-6 18:29:52 浏览次数:458

彩色分色工艺用于对原稿进行数字式扫描,将原稿分成红色、绿色和蓝色的成分。在数字式成像开发出来以前,彩色分色的传统方法是对图像照相3次,每次都用相对应颜色的滤色片过滤不同的光线。

Color separation process for digital scanning of the original manuscript will be divided into red, green and blue components. Before the digital imaging is developed, the traditional method of color separation of the image photography 3 times, each time with the corresponding color filter color different light.

不过分色以後,所需的结果是3个灰色图像,其分别代表原稿的红色、绿色和蓝色的成份:

But after separation, the desired result is 3 gray image, which represent the original red, green and blue components:

下一步是转换每一色分色片。在生成红色成分的阴图图像时,生成的图像代表图像青的成分。同样,也生成绿色成份、蓝色成份的阴图片,以便相应地生成品红色和黄色的分色片。

The next step is to convert each color separations. In the negative image generation red component, the image represents the green component image. Similarly, Yin pictures also generate green and blue components of components, so that corresponding products of red and yellow color.

青、品红和黄色是减色法原色,因为每种颜色代表的是从白光中减去一种加色法原色所剩的两种加色法原色。青色、品红色和黄色是颜色复制中三种主要的颜料。在这三种颜色在印刷中组合在一起,可以对原稿进行合理的复制,但实际情况下并非如此。

Cyan, magenta and yellow is subtractive, because each color represents two kinds of additive primaires left in a white light is subtracted from the additive primaires. Blue, red and yellow are three main colors in the color reproduction. The three colors are combined together in the printing to make a reasonable copy of the original, but it is not the case in practice.

由于油墨颜料的限制,所产生的较暗的颜色比较脏,发污。为了解决这个问题,还要制作一张黑版,以改善暗部的颜色,提高图像的反差。已经有多种技术可以从原稿图像制作这块黑版;这些技术包括灰色成份替换、底色去除和底色增加。可有可无的东西,而忽略了其本质的制冷制热性能。

Due to the limitation of the ink pigment, the darker color is dirty and dirty. In order to solve this problem, but also make a black version, to improve the shadow and improve image contrast. There are many kinds of technology can make the black version from the original image; these include grey component replacement, and increase the background color removal. Not essential things, while ignoring the essence of the refrigeration and heat performance.
