做画册印刷时怎么更好的调色?

来源:http://www.jindingyinshua.com   日期:2019-04-29

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, 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色域空间比CMYK大点,所以在正式转入印件前都是以RGB方式处置的,当然也可以用Lab方式,只是普通默许是RGB方式的。为什么要中止这样的转换呢?就是由于RGB三色属于光的三原色,契合颜色加法;而CMYK是油墨四原色,契合色减法,其实黑墨也可以不算原色,但普通是用它替代其他三色的混合。直观的表现就是同一幅图像,CMYK方式下是比较暗的。
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。由于颜色鲜艳、光亮度好、色相准确是彩印产品的基本央求,要完成这个央求首先必需准确分配好印刷油墨。所以,操作者要控制好颜色学问和调墨工艺。

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.
控制三原色变化规律,以便完成准确油墨分配:任何一种颜色都能应用三原色的不同比例混合调成,油墨的色相变化,正是应用这个规律。如三原色油墨等量混合分配后可变成黑色(近似)。三原色油墨等量混调并参与不
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 ,即可配成各种不同颜色的浅灰色墨。
With the same proportion of white ink, it can be blended with various colors of light gray ink.
若三原色油墨按各种比例混调,即可分配成多种不同色相的间色或复色,但其色相倾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分配后,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,参与白墨后其色相就显得更明亮。反之,参与黑色油墨后,其色相就变得深。
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:应用补色理论纠正偏色,进步伐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中止认真的鉴赏和分析,控制一个基本准绳,即三原色是分配任何墨色的基础色。普通来说,应用三原色的变化规律,除金银颜色外,任何复杂的颜色都能分配出来。但是,在工艺理论过程中,仅靠三原色墨要分配出无数种的油墨颜色来,还是不够的。
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,理论上制造油墨的颜料不是很标准的,致使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,在理论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、绿色等油墨适量参与,才干抵达所需油墨色相。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缺乏的。任何复杂的颜色,总是在三原色范围内变化的,只需控制好这个准绳,调墨也就不成问题了。当颜色分析肯定主色和辅色墨及比例后,即可中止分配。但假定分配出的色相有倾向,可用补色理论来纠正其色相。
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.
