彩色設(shè)計印刷是用彩色方式復(fù)制圖像或文字的復(fù)制方式（與此相對應(yīng)的是只有黑白的印刷方式，或稱單色印刷）。它包括了許多步驟，或稱轉(zhuǎn)換過程，才能產(chǎn)生高質(zhì)量的彩色復(fù)制品。下面小編為您講講濟南彩色設(shè)計印刷過程中的分色工藝事項。

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.

彩色分色工藝用于對原稿進(jìn)行數(shù)字式掃描，將原稿分成紅色、綠色和藍(lán)色的成分。在數(shù)字式成像開發(fā)出來以前，彩色分色的傳統(tǒng)方法是對圖像照相3次，每次都用相對應(yīng)顏色的濾色片過濾不同的光線。不過分色以後，所需的結(jié)果是3個灰色圖像，其分別代表原稿的紅色、綠色和藍(lán)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:

下一步是轉(zhuǎn)換每一色分色片。在生成紅色成分的陰圖圖像時，生成的圖像代表圖像青的成分。同樣，也生成綠色成份、藍(lán)色成份的陰圖片，以便相應(yīng)地生成品紅色和黃色的分色片。

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、品紅和黃色是減色法原色，因為每種顏色代表的是從白光中減去一種加色法原色所剩的兩種加色法原色。青色、品紅色和黃色是顏色復(fù)制中三種主要的顏料。

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.

在這三種顏色在印刷中組合在一起，可以對原稿進(jìn)行合理的復(fù)制，但實際情況下并非如此。由于油墨顏料的限制，所產(chǎn)生的較暗的顏色比較臟，發(fā)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.

為了解決這個問題，還要制作一張黑版，以改善暗部的顏色，提高圖像的反差。已經(jīng)有多種技術(shù)可以從原稿圖像制作這塊黑版；這些技術(shù)包括灰色成份替換、底色去除和底色增加。更多相關(guān)事項就來我們網(wǎng)站http://www.bosije.com咨詢吧！

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.
