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.
在前期制作中，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模式處理的，當然也可以用Lab模式，只是一般默認是RGB模式的。為什么要進行這樣的轉換呢？就是因為RGB三色屬于光的三原色，符合顏色加法；而CMYK是油墨四原色，符合色減法，其實黑墨也可以不算原色，但一般是用它代替其他三色的混合。直觀的表現就是同一幅圖像，CMYK模式下是比較暗的。
In the previous production, because RGB gamut space is larger than CMYK, it is processed in RGB mode before it is formally transferred to print. Of course, it can also be processed in Lab mode, which is only the default RGB mode. Why do we make such a transition? It is because RGB three colors belong to the three primary colors of light, which accords with color addition; while CMYK is the four primary colors of ink, which accords with color subtraction. In fact, black ink can not be considered as the primary color, but it is generally used to replace the mixing of other three colors. The most intuitive performance is the same image, CMYK mode is darker.
調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。因為色彩鮮艷、光亮度好、色相準確是彩印產品的基本要求，要實現這個要求必須準確調配好印刷油墨。所以，操作者要掌握好色彩知識和調墨工藝。
Ink blending 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 achieve this requirement, we must first accurately mix printing ink. Therefore, operators should master color knowledge and ink mixing technology.
掌握三原色變化規律，以便實現準確油墨調配：任何一種顏色都能利用三原色的不同比例混合調成，油墨的色相變化，正是利用這個規律。如三原色油墨等量混合調配后可變成黑色（近似）。三原色油墨等量混調并加入不
Grasp the changing law of the three primary colors in order to achieve accurate ink blending: any color can be mixed with different proportions of the three primary colors, and the change of the color phase of the ink is precisely using this law. If the tri-primary ink is mixed and blended equally, it can become black (approximate). Equivalent mixing of three primary colour inks and adding no
同比例的白墨 ,即可配成各種不同色調的淺灰色墨。
With the same proportion of white ink, it can be blended with various tones of light gray ink.
若三原色油墨按各種比例混調，即可調配成多種不同色相的間色或復色，但其色相偏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調配后，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，加入白墨后其色相就顯得更明亮。反之，加入黑色油墨后，其色相就變得深。
If the three primary colour inks are mixed in various proportions, they can be blended into a variety of different colour phases, but the colour phase is biased to the larger proportion of the primary colour. If the two primary inks are blended equally, they can become standard inter-color. When the two primary inks are blended in different proportions, they can be blended 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 white ink is added. Conversely, when black ink is added, the color becomes darker.
分析原稿色相：利用補色理論糾正偏色，提高調墨效果當接到畫冊印刷色稿后，應對原稿中的各種顏色進行認真的鑒賞和分析，掌握一個基本原則，即三原色是調配任何墨色的基礎色。一般來說，應用三原色的變化規律，除金銀色彩外，任何復雜的顏色都能調配出來。但是，在工藝實踐過程中，僅靠三原色墨要調配出無數種的油墨顏色來，還是不夠的。因為，實際上制造油墨的顏料不是很標準的，甚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，在實際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、綠色等油墨適量加入，才能達到所需油墨色相。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不足的。任何復雜的顏色，總是在三原色范圍內變化的，只要掌握好這個原則，調墨也就不成問題了。當色彩分析確定主色和輔色墨及比例后，即可進行調配。但如果調配出的色相有偏差，可用補色理論來糾正其色相。
Analysis of the original color phase: Use complementary color theory to correct bias and improve toner effect. After receiving the printed color manuscript in the picture album, first of all, we should carefully appreciate and analyze the various colors in the original, and grasp a basic principle, that is, three primary colors are the basic color of any ink. Generally speaking, any complex color can be blended except gold and silver color by applying the changing rule of the three primary colors. However, in the process of technological practice, it is not enough that only three primary colors of ink should be used to mix out innumerable kinds of ink colors. Because, in fact, the pigments used to make inks are not very standard, and even the color of each batch of inks is inevitably different to some extent. Therefore, in practical work, we should also use such inks as medium blue, dark blue, light blue, light blue, medium yellow, deep yellow, light yellow, golden, orange, deep red, light red, black, green and so on to achieve the required ink color. There are many kinds of inks, but in any case, except the three primary colors, other colors are used to supplement the shortcomings of the three primary colors. Any complex color always varies in the range of three primary colors. As long as we master this principle well, it will not be a problem to adjust ink. When the color analysis determines the principal color and auxiliary color ink and proportion, it can be adjusted. However, if the color is mismatched, the complementary theory can be used to correct the color.
