在畫冊印刷過程中，重要的一個環節就是畫冊印刷調色，一個印刷師傅對產品顏色的把握準確與否，關乎著產品印刷出來的質量好壞。
In the process of album printing, the most important link is the color matching of album printing. The accuracy of a printer's grasp of the color of a product is related to the quality of the product printed.
在前期制造中，由于RGB色域空間比CMYK大點，所以在正式轉入印件前都是以RGB方式處置的，當然也可以用Lab方式，只是普通默許是RGB方式的。為什么要中止這樣的轉換呢?就是由于RGB三色屬于光的三原色，契合顏色加法;而CMYK是油墨四原色，契合色減法，其實黑墨也可以不算原色，但普通是用它替代其他三色的混合。直觀的表現就是同一幅圖像，CMYK方式下是比較暗的。
In the early manufacture, because RGB gamut space is larger than CMYK, it is always handled by RGB mode before it is transferred to the printed copy. Of course, it can also be handled by Lab mode, but it is generally accepted by RGB mode. Why stop such conversion? It is because RGB three colors belong to the three primary colors of light and match the color addition; while CMYK is the four primary colors of ink, match the color subtraction, in fact, black ink can not be considered the primary color, but it is commonly used to replace the mixing of other three colors. The most intuitive performance is the same image, CMYK mode is darker.
分配油墨是彩印工藝中的一項重要工作，這項工作做得如何，直接關系到產品的畫冊印刷質量。由于顏色鮮艷、光亮度好、色相準確是彩印產品的基本央求，要完成這個央求必需準確分配好印刷油墨。所以，操作者要控制好顏色學問和調墨工藝。
Distribution of ink is an important work in color printing process. How this work works is directly related to the quality of picture album printing. Because bright color, good brightness and accurate hue are the basic requirements of color printing products, in order to complete this requirement, it is necessary to distribute printing ink accurately. Therefore, operators should control the knowledge of color and inking technology.
控制三原色變化規律，以便完成準確油墨分配：任何一種顏色都能應用三原色的不同比例混合調成，油墨的色相變化，正是應用這個規律。如三原色油墨等量混合分配后可變成黑色(近似)。三原色油墨等量混調并參與不
Control the changing rule of three primary colors in order to complete the accurate ink distribution: any color can be mixed with different proportions of three primary colors. The change of color phase of ink is exactly the application of this rule. If the three primary colours are mixed equally, they can turn black (approximate). Tri-Primary Ink Mixing Equally and Participating in No-Primary Ink Mixing
同比例的白墨 ,即可配成各種不同顏色的淺灰色墨。
With the same proportion of white ink, it can be blended with various colors of light gray ink.
若三原色油墨按各種比例混調，即可分配成多種不同色相的間色或復色，但其色相傾向于比例大的原色色相。若兩種原色墨等量混調后，可成為標準間色;兩種原色墨按不同比例混合分配后，可配成多種不同色相的間色，但其色相趨向于比例大的原色色相。此外，任何顏色的油墨中，參與白墨后其色相就顯得更明亮。反之，參與黑色油墨后，其色相就變得深。
If the three primary colour inks are mixed in various proportions, they can be divided into different colour phases or duplicate colours, but the colour phase tends to be larger in proportion. If the two primary inks are mixed equally, they can become standard inter-color. After mixing and distributing the two primary inks in different proportions, they can be matched into various inter-color phases, but their color phases tend to be larger in proportion. In addition, the color of any color ink becomes brighter when it participates in white ink. Conversely, the color of black ink becomes darker when it is used.
分析原稿色相：應用補色理論糾正偏色，進步伐墨效果當接到畫冊印刷色稿后，應對原稿中的各種顏色中止認真的鑒賞和分析，控制一個基本準繩，即三原色是分配任何墨色的基礎色。普通來說，應用三原色的變化規律，除金銀顏色外，任何復雜的顏色都能分配出來。但是，在工藝理論過程中，僅靠三原色墨要分配出無數種的油墨顏色來，還是不夠的。
Analyzing the color phase of the original manuscript: Correct the bias by applying the complementary color theory, improve the effect of cutting ink. When receiving the printed color manuscript of the album, first of all, we should stop earnestly appreciating and analyzing the various colors in the original manuscript, and control a basic criterion, that is, the three primary colors are the basic colors of any ink distribution. Generally speaking, any complex color can be assigned except gold and silver color by applying the changing rule of the three primary colors. However, in the process of technological theory, it is not enough to distribute innumerable ink colours only by three primary colours.
由于，理論上制造油墨的顏料不是很標準的，致使每批出產的油墨在顏色上免不了存有一定程度的差異。所以，在理論工作中還應采用如中藍、深藍、淡藍、射光藍、中黃、深黃、淡黃、金紅、桔紅、深紅、淡紅、黑、綠色等油墨適量參與，才干抵達所需油墨色相。油墨的種類很多，但不管如何，除了三原色墨以外，其他顏色都是用以補充三原色的缺乏的。任何復雜的顏色，總是在三原色范圍內變化的，只需控制好這個準繩，調墨也就不成問題了。當顏色分析肯定主色和輔色墨及比例后，即可中止分配。但假定分配出的色相有傾向，可用補色理論來糾正其色相。
In theory, the pigments used to make inks are not very standard, so there are certain differences in the color of each batch of inks. Therefore, in theoretical work, such as medium blue, dark blue, light blue, light blue, medium yellow, dark yellow, light yellow, golden, orange, deep red, light red, black, green and other inks should also be used in order to reach the required ink color. There are many kinds of ink, but in any case, except the three primary colors, other colors are used to supplement the lack of three primary colors. Any complex color always varies within the range of three primary colors. As long as this criterion is well controlled, ink adjustment will not be a problem. When the color analysis confirms the principal color and auxiliary color ink and proportion, the allocation can be discontinued. However, assuming that the assigned hues have a tendency, the complementary theory can be used to correct their hues.
