1. Ink color

　　油墨的顏色取決于顏料的選擇和組成。為了適應商品和包裝的需要，開發了新的油墨顏色品種，提高了傳統色彩的質量。

　　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環境光的影響。如果在標準下光源是綠、紅、白等。但如果環境光或曝光條件發生變化，如紅光變成白色油墨膜會使白色包裝印刷油墨變紅。任何一種包裝承印物表面擺設的顏色都是不一目了然的。應根據色度等知識，不間斷地研究不朱膜的色彩變化規律，才能印出好的產物。

　　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.印刷和裝飾中相同顏色和不同光譜的概念

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

　　為了滿足濟南包裝印刷油墨顏色品種的需要，僅僅幾種顏色是不夠的。必須經過一定的配色過程才能得到市場上產品的彩色油墨系列化的要求。新色相是通過印刷中間色或復合色獲得的，符合常規包裝印刷規律和配色規律。

　　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.

　　為了實現上述要求，提出了同色異譜色的概念。不同顏色油墨樣品的光譜分布對于彩色包裝印刷油墨的顏色匹配非常重要。也就是說，使用不同的油墨顏色可以調配到相同的油墨顏色品種上。實際的顏色匹配只能達到一定程度的近似，可以通過光譜反射因子曲線的形狀來評價。兩個樣本的反射率因子曲線越相似，重疊越多，相交點越多，越能證明混合樣本的顏色與樣本的顏色相似。還通過兩種油墨樣品色度的計算差異進行定量分析。來顯示它們的顏色有多一致。

　　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.顏色分配的基本知識

　　3. Basic knowledge of color distribution

　　在包裝印刷油墨體系中,綁定是無色或微顏色液體,折射率和水非常接近,所以綁定有一定程度的透明度,當添加顏色,填充,因為顏色,襯塊光,導致墨水的光學性質的變化。

　　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.

　　當陽光照射到黃色油墨膜上時，它吸收太陽光的藍色光譜，發出黃色和綠色的光。當反射的黃光和綠光遇到藍色色素粒子時，反射的藍光傾向于只吸收綠光。經過一系列的反射、折射后才有綠色油墨的墨膜。因此，我們稱這種油墨的混色是減法(吸收彼此所需的波長，但不被吸收的光譜反射)，這就是混色(或復色)的來源。

　　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).

　　在我國的包裝印刷油墨行業由于采用減法原理，所以采用三基色互補色。

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

　　我們在濟南的印刷廠使用多種油墨顏色，創造出豐富多彩的油墨顏色。

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

　　如果包裝印刷的色彩裝飾設計充分構思后,三原色的黃色、品紅色,綠色三三個紅色,綠色,藍色,然后四個復雜的紫色,橄欖綠色,黑色,青銅,可以組合成一個新形式的表達式,如果你知道不同油墨色調(色調),不同油墨的明度和彩度組合油墨顏色分配在一起,也會給人一種柔軟和美麗的和諧感覺。

　　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.

　　在國內外包裝油墨色卡,顏色的選擇,除了三個主要的顏色,絕大多數的復合色,復雜(組合)分配本身就是一個顏色科學、包裝印刷的顏色準備或更終使用我們的視覺檢查檢查其效果,好,壞,利弊。貨物包裝印刷裝飾顏色的使用,我們需要裝修全系列的顏色,不斷調整工作,生活環境，會給人們一個良性的刺激，有利于工作和生活質量的提高。

　　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.
