彩色设计印刷是用彩色方式复制图像或文字的复制方式（与此相对应的是只有黑白的印刷方式，或称单色印刷）。它包括了许多步骤，或称转换过程，才能产生高质量的彩色复制品。下面小编为您讲讲济南彩色设计印刷过程中的分色工艺事项。

Color design printing is a method of reproducing images or text in color (corresponding to only black and white printing, also known as monochrome printing). It involves many steps, also known as the conversion process, in order to produce high-quality color replicas. Below, the editor will talk about the color separation process in Jinan's color design and printing process.

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。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：

The color separation process is used to digitally scan the original, dividing it into red, green, and blue components. Before the development of digital imaging, the traditional method of color separation was to take three photos of the image, each time filtering different rays with corresponding color filters. However, after color separation, the desired result is three gray images, which represent the red, green, and blue components of the original manuscript:

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 separation chip. When generating a negative image with a red component, the generated image represents the blue component of the image. Similarly, negative images of green and blue components are also generated to generate corresponding red and yellow color separations.

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。

Cyan, magenta and yellow are Subtractive color primary colors, because each color represents the two Additive color primary colors left after subtracting one Additive color primary color from white light. Cyan, magenta, and yellow are the three main pigments used in color reproduction.

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。由于油墨颜料的限制，所产生的较暗的颜色比较脏，发污。

Combining these three colors together in printing allows for reasonable reproduction of the original, but in reality, this is not the case. Due to the limitations of ink and pigments, the resulting darker colors are dirty and dirty.

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。更多相关事项就来我们网站https://www.sdhzyw.com咨询吧！

To solve this problem, a black plate needs to be made to improve the color of the dark areas and increase the contrast of the image. There are already multiple technologies available to create this black version from the original image; These technologies include gray component replacement, background color removal, and background color increase.
