畫冊印刷調色的重要性!
The importance of color matching in album printing!
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, an important link is album printing color matching. The accuracy of a printing master's grasp of product color is related to the quality of product printing.
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 pre production, due to the RGB gamut space is larger than CMYK, so before the official transfer to printing, it is processed in RGB mode, of course, you can also use lab mode, but the default is RGB mode. Why do you want to do this conversion? It is because RGB three colors belong to the three primary colors of light, in line with color addition; while CMYK is ink four primary colors, in line with color subtraction, in fact, black ink can not be counted as primary color, but it is generally used to replace the mixture of other three colors. Intuitive performance is the same image, CMYK mode is relatively dark.
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。
The allocation of ink is an important work in color printing process. How this work is done is directly related to the printing quality of product album. Because bright color, good brightness and accurate hue are the basic requirements of color printing products. To achieve this requirement, it is necessary to accurately allocate printing ink. Therefore, the operator should master the color knowledge and inking process.
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
Master the changing law of the three primary colors, so as to realize the accurate ink mixing: any color can be mixed with different proportions of the three primary colors, and the color change of the ink is exactly using this law. Such as three primary color ink mixed after deployment can become black (approximate). Three primary color ink mixed with the same amount and add No
同比例的白墨 ,即可配成各種不同色調的淺灰色墨。
The same proportion of white ink, you can match a variety of different 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 inks are mixed according to various proportions, they can be blended into a variety of intercolor or multicolor of different hues, but the hue tends to the primary color with large proportion. If two kinds of primary color inks are mixed in equal amount, they can become standard intercolor; after mixing and mixing the two primary color inks according to different proportions, they can be matched into a variety of intercolor with different hues, but the hue tends to be the primary hue with large proportion. In addition, any color of ink, after adding white ink, its hue appears more bright. On the contrary, after adding black ink, its hue becomes deep.

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。
Analysis of the original color: use the complementary color theory to correct the color deviation and improve the ink mixing effect. After receiving the color draft of the picture album, first of all, carefully appreciate and analyze the various colors in the original, and master a basic principle, that is, the three primary colors are the basic colors for the deployment of any ink color. Generally speaking, the application of three primary color change law, in addition to gold and silver color, any complex color can be blended out.
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。
However, in the process of process practice, it is not enough to rely on the three primary color ink to allocate countless ink colors. Because, in fact, the production of ink pigment is not very standard, and even each batch of ink in the color inevitably there is a certain degree of difference. Therefore, in the actual work should also be used such as blue, dark blue, light blue, light blue, yellow, dark yellow, light yellow, golden red, orange, dark red, light red, black, green and other inks to be added appropriately, in order to achieve the required ink hue. There are many kinds of ink, but no matter how, in addition to the primary color ink, other colors are used to supplement the three primary colors. Any complex color, always changes in the range of three primary colors, as long as you master this principle, inking is not a problem. When the color analysis to determine the main color and auxiliary color ink and proportion, can be mixed. But if there is deviation in the hue, the complementary color theory can be used to correct the hue.
