色彩在印刷中占据重要的位置，是产生视觉冲击力和感染力的重要前提，是吸引消费者目光甚至引发购买的直观因素，那么，如何要怎么保证印刷效果的色彩，济南印刷包装厂家分享印刷的色彩小知识供朋友们参考。

Color occupies an important position in printing, is an important prerequisite for generating visual impact and appeal, and is an intuitive factor to attract consumers' eyes and even trigger purchase. So, how to ensure the color of printing effect, Jinan printing and packaging manufacturers share the color knowledge of printing for friends' reference.

1、颜色的一致性

1. Color consistency

确保色彩一致性的一个重要方法就是让客户在标准的照明条件下观察彩色样张和印刷样张，并获得他们的认可。为了减少颜色在传递和复制过程中的变化，印刷业特别制定了标准的颜色观察条件，既标准颜色观察池(为观测样张或其他印刷品所设置的一个具有稳定环境的光源控制区域)。

An important way to ensure color consistency is to let customers observe color samples and print samples under standard lighting conditions and obtain their approval. In order to reduce the change of color in the process of transmission and reproduction, the printing industry has specially formulated standard color observation conditions, namely, standard color observation pool (a light source control area with stable environment set for observation of sample or other printed matter).

这个颜色观察池有两个关键要素：一是照明(色温为5000K)；二是中性灰环境(MunsellN8)。

This color observation pool has two key elements: one is lighting (color temperature is 5000K); The second is the neutral gray environment (Munsell N8).

在观察池上检查颜色是非常重要的，因为我们检查颜色时的照明条件和周围环境会影响我们对颜色的感知。如果没有标准的观察池，那我们也可以在非直接照射的日光下观看样张。

It is very important to check the color on the observation pool, because the lighting conditions and surrounding environment when we check the color will affect our perception of color. If there is no standard observation pool, we can also view the sample in the indirect sunlight.

2、照明的影响

2. Influence of lighting

当我们在不同的照明条件下观察颜色的时候，看到的效果也是不同的。我们在观察颜色时需要注意的另外一个问题就是同色异谱。所谓“同色异谱”就是当两个样张在某种光源下，呈现的颜色是相同的，而在另外一种光源下，呈现的颜色则是不同的。

When we observe colors under different lighting conditions, we see different effects. Another problem we need to pay attention to when observing colors is metamerism. The so-called "homochromatic metamerism" is that when two samples are exposed to one light source, the color is the same, while under another light source, the color is different.

在观察颜色的时候，保持照明条件的稳定一致是非常重要的。我们之所以会选用色温为5000K的光源，主要是因为这种光源是由红光、绿光和蓝光混合而成的，能为人们提供稳定一致的观察环境。

When observing colors, it is very important to keep the lighting conditions stable and consistent. The reason why we choose the light source with a color temperature of 5000K is mainly because this light source is composed of red light, green light and blue light, which can provide a stable and consistent observation environment for people.

3、环境影响

3. Environmental impact

我们观察印刷样张时的周围环境是否会对颜色产生影响?临近色，也就是与被观察的样张或印张相近的颜色可以影响到人们对颜色的感知。

Do we observe whether the surrounding environment when printing the sample will affect the color? Proximity color, that is, the color close to the observed sample or print, can affect people's perception of color.

这就是所谓的“临界效应”，它在一定程度上反映了在观察样张时使用中性环境的重要性。据了解，在周围环境中使用标准灰色漆(MunsellN8)可有效减少人们在确认色彩时所受的邻近色的影响。

This is the so-called "critical effect", which to some extent reflects the importance of using neutral environment when observing samples. It is understood that the use of standard grey paint (Munsell N8) in the surrounding environment can effectively reduce the impact of adjacent colors on people when confirming colors.

4、纸张

4. Paper

减色法是指在白色环境中(通常是纸张)用黄、品红、青和黑色油墨来混合成色的方法。在这个颜色复制过程中，有一个元素会对颜色的上机印刷效果产生重大影响，那就是纸张。

Subtraction refers to the method of mixing yellow, magenta, cyan and black inks in a white environment (usually paper). In the process of color reproduction, there is one element that will have a significant impact on the effect of color printing, that is, paper.

同样的墨色可能会在不同的纸张上产生不同的印刷效果。纸张越白，能在印刷机上复制出的色域就越大。如果纸张的白度不够，那么它在印刷机上复制出的色域就比较小。

The same ink color may produce different printing effects on different paper. The whiter the paper, the larger the color gamut that can be reproduced on the printer. If the whiteness of the paper is not enough, the color gamut copied on the printing machine is relatively small.

印刷不是一个完全匹配的过程，这主要因为在颜色复制过程中有很多颜色复制系统。摄影就是一个典型的颜色复制系统，打样和印刷也是如此。更多相关印刷包装的事情就来我们网站http://www.xinfengyinshua.cn咨询吧！

Printing is not a complete matching process, mainly because there are many color reproduction systems in the color reproduction process. Photography is a typical color reproduction system, so is proofing and printing. For more information about printing and packaging, please visit our website http://www.xinfengyinshua.cn Ask!
