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 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.

　　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。

　　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

　　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 ,即可配成各种不同色调的浅灰色墨。

　　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 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：利用补色理论纠正偏色，提高调墨效果当接到画册印刷色稿后，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。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。

　　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.
