画册印刷调色的重要性!

The importance of color matching in album printing!
在画册印刷过程中,重要的一个环节就是画册印刷调色,一个印刷师傅对产品颜色的把握准确与否,关乎着产品印刷出来的质量好坏。
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色域空间比CMYK大点,所以在正式转入印件前都是以RGB模式处理的,当然也可以用Lab模式,只是一般默认是RGB模式的。为什么要进行这样的转换呢?就是因为RGB三色属于光的三原色,符合颜色加法;而CMYK是油墨四原色,符合色减法,其实黑墨也可以不算原色,但一般是用它代替其他三色的混合。直观的表现就是同一幅图像,CMYK模式下是比较暗的。
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.
调配油墨是彩印工艺中的一项重要工作,这项工作做得如何,直接关系到产品的画册印刷质量。因为色彩鲜艳、光亮度好、色相准确是彩印产品的基本要求,要实现这个要求首先必须准确调配好印刷油墨。所以,操作者要掌握好色彩知识和调墨工艺。
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.
掌握三原色变化规律,以便实现准确油墨调配:任何一种颜色都能利用三原色的不同比例混合调成,油墨的色相变化,正是利用这个规律。如三原色油墨等量混合调配后可变成黑色(近似)。三原色油墨等量混调并加入不
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 ,即可配成各种不同色调的浅灰色墨。
The same proportion of white ink, you can match a variety of different tones of light gray ink.

若三原色油墨按各种比例混调,即可调配成多种不同色相的间色或复色,但其色相偏向于比例大的原色色相。若两种原色墨等量混调后,可成为标准间色;两种原色墨按不同比例混合调配后,可配成多种不同色相的间色,但其色相趋向于比例大的原色色相。此外,任何颜色的油墨中,加入白墨后其色相就显得更明亮。反之,加入黑色油墨后,其色相就变得深。
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:利用补色理论纠正偏色,提高调墨效果当接到画册印刷色稿后,首先应对原稿中的各种颜色进行认真的鉴赏和分析,掌握一个基本原则,即三原色是调配任何墨色的基础色。一般来说,应用三原色的变化规律,除金银色彩外,任何复杂的颜色都能调配出来。
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,在工艺实践过程中,仅靠三原色墨要调配出无数种的油墨颜色来,还是不够的。因为,实际上制造油墨的颜料不是很标准的,甚至每批出产的油墨在颜色上免不了存有一定程度的差异。所以,在实际工作中还应采用如中蓝、深蓝、淡蓝、射光蓝、中黄、深黄、淡黄、金红、桔红、深红、淡红、黑、绿色等油墨适量加入,才能达到所需油墨色相。油墨的种类很多,但不管如何,除了三原色墨以外,其他颜色都是用以补充三原色的不足的。任何复杂的颜色,总是在三原色范围内变化的,只要掌握好这个原则,调墨也就不成问题了。当色彩分析确定主色和辅色墨及比例后,即可进行调配。但如果调配出的色相有偏差,可用补色理论来纠正其色相。
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.
