1. Ink color

　　油墨的颜色取决于颜料的选择和组成。为了适应商品和包装的需要，开发了新的油墨颜色品种，提高了传统色彩的质量。

　　The color of the ink depends on the choice and composition of the pigment. In order to meet the needs of commodities and packaging, new ink color varieties have been developed to improve the quality of traditional colors.

　　承印物不朱的色彩往往受其自身色度和环境光的影响。如果在标准下光源是绿、红、白等。但如果环境光或曝光条件发生变化，如红光变成白色油墨膜会使白色包装印刷油墨变红。任何一种包装承印物表面摆设的颜色都是不一目了然的。应根据色度等知识，不间断地研究不朱膜的色彩变化规律，才能印出好的产物。

　　Substrate ink color is often affected by its own chromaticity and ambient light. If the light source is green, red, white, etc. However, if the ambient light or exposure conditions change, such as red light into white ink film, the white packaging printing ink will turn red. Any kind of packaging substrate surface decoration color is not clear at a glance. According to the knowledge of chroma and so on, we should continuously study the color change rule of the ink film in order to print a good product.

　　2.印刷和装饰中相同颜色和不同光谱的概念

　　2. Concepts of the same color and different spectrum in printing and decoration

　　为了满足济南包装印刷油墨颜色品种的需要，仅仅几种颜色是不够的。必须经过一定的配色过程才能得到市场上产品的彩色油墨系列化的要求。新色相是通过印刷中间色或复合色获得的，符合常规包装印刷规律和配色规律。

　　In order to meet the needs of Jinan packaging printing ink color varieties, only a few colors are not enough. It is necessary to go through a certain color matching process in order to get the requirements of color ink serialization of products on the market. The new color phase is obtained by printing intermediate color or compound color, which conforms to the regular packaging printing law and color matching law.

　　为了实现上述要求，提出了同色异谱色的概念。不同颜色油墨样品的光谱分布对于彩色包装印刷油墨的颜色匹配非常重要。也就是说，使用不同的油墨颜色可以调配到相同的油墨颜色品种上。实际的颜色匹配只能达到一定程度的近似，可以通过光谱反射因子曲线的形状来评价。两个样本的反射率因子曲线越相似，重叠越多，相交点越多，越能证明混合样本的颜色与样本的颜色相似。还通过两种油墨样品色度的计算差异进行定量分析。来显示它们的颜色有多一致。

　　In order to achieve the above requirements, the concept of homochromatic and heterochromatic is proposed. The spectral distribution of different color ink samples is very important for color matching of color packaging printing ink. In other words, using different ink colors can be deployed to the same ink color varieties. The actual color matching can only reach a certain degree of approximation, which can be evaluated by the shape of spectral reflection factor curve. The more similar the reflectance factor curves of the two samples are, the more overlapped and the more intersected points are, the more it can be proved that the color of the mixed samples is similar to that of the samples. The quantitative analysis is also carried out by calculating the difference of chroma between the two ink samples. To show how consistent their colors are.

　　3.颜色分配的基本知识

　　3. Basic knowledge of color distribution

　　在包装印刷油墨体系中,绑定是无色或微颜色液体,折射率和水非常接近,所以绑定有一定程度的透明度,当添加颜色,填充,因为颜色,衬块光,导致墨水的光学性质的变化。

　　In the packaging printing ink system, the binding is a colorless or micro color liquid, the refractive index is very close to water, so the binding has a certain degree of transparency, when adding color, filling, because of color, block light, resulting in changes in the optical properties of the ink.

　　当阳光照射到黄色油墨膜上时，它吸收太阳光的蓝色光谱，发出黄色和绿色的光。当反射的黄光和绿光遇到蓝色色素粒子时，反射的蓝光倾向于只吸收绿光。经过一系列的反射、折射后才有绿色油墨的墨膜。因此，我们称这种油墨的混色是减法(吸收彼此所需的波长，但不被吸收的光谱反射)，这就是混色(或复色)的来源。

　　When the sun shines on the yellow ink film, it absorbs the blue spectrum of sunlight and emits yellow and green light. When the reflected yellow and green light meet the blue pigment particles, the reflected blue light tends to absorb only the green light. After a series of reflection and refraction, there is a green ink film. Therefore, we call the mixing of this ink subtraction (absorbing the wavelength needed by each other, but not the spectral reflection of absorption), which is the source of mixing (or multicolor).

　　在我国的包装印刷油墨行业由于采用减法原理，所以采用三基色互补色。

　　In China's packaging printing ink industry, due to the principle of subtraction, three complementary primary colors are used.

　　我们在济南的印刷厂使用多种油墨颜色，创造出丰富多彩的油墨颜色。

　　Our printing factory in Jinan uses a variety of ink colors to create a variety of ink colors.

　　如果包装印刷的色彩装饰设计充分构思后,三原色的黄色、品红色,绿色三三个红色,绿色,蓝色,然后四个复杂的紫色,橄榄绿色,黑色,青铜,可以组合成一个新形式的表达式,如果你知道不同油墨色调(色调),不同油墨的明度和彩度组合油墨颜色分配在一起,也会给人一种柔软和美丽的和谐感觉。

　　If the color decoration design of packaging printing is fully conceived, three primary colors of yellow, magenta, green, three red, green, blue, and then four complex purple, olive green, black, bronze can be combined into a new form of expression. If you know different ink tones (tones), different ink brightness and color combination ink colors are distributed together, It will also give people a soft and beautiful feeling of harmony.

　　在国内外包装油墨色卡,颜色的选择,除了三个主要的颜色,绝大多数的复合色,复杂(组合)分配本身就是一个颜色科学、包装印刷的颜色准备或更终使用我们的视觉检查检查其效果,好,坏,利弊。货物包装印刷装饰颜色的使用,我们需要装修全系列的颜色,不断调整工作,生活环境，会给人们一个良性的刺激，有利于工作和生活质量的提高。

　　At home and abroad packaging ink color card, color selection, in addition to three main colors, the vast majority of composite colors, complex (combination) distribution itself is a color science, packaging and printing color preparation or final use of our visual inspection to check its effect, good, bad, advantages and disadvantages. We need to decorate the whole series of colors for the use of packaging, printing and decoration colors, and constantly adjust the working and living environment, which will give people a benign stimulation and help improve the quality of work and life.
