色彩在印刷中占據(jù)重要的位置，是產(chǎn)生視覺(jué)沖擊力和感染力的重要前提，是吸引消費(fèi)者目光甚引發(fā)購(gòu)買(mǎi)的直觀因素，那么，如何要怎么保證印刷效果的色彩，濟(jì)南印刷包裝廠家分享印刷的色彩小知識(shí)供朋友們參考。

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、顏色的一致性

1. Color consistency

確保色彩一致性的一個(gè)重要方法就是讓客戶在標(biāo)準(zhǔn)的照明條件下觀察彩色樣張和印刷樣張，并獲得他們的認(rèn)可。為了減少顏色在傳遞和復(fù)制過(guò)程中的變化，印刷業(yè)特別制定了標(biāo)準(zhǔn)的顏色觀察條件，既標(biāo)準(zhǔn)顏色觀察池(為觀測(cè)樣張或其他印刷品所設(shè)置的一個(gè)具有穩(wěn)定環(huán)境的光源控制區(qū)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).

這個(gè)顏色觀察池有兩個(gè)關(guān)鍵要素：一是照明(色溫為5000K)；二是中性灰環(huán)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).

在觀察池上檢查顏色是非常重要的，因?yàn)槲覀儥z查顏色時(shí)的照明條件和周圍環(huán)境會(huì)影響我們對(duì)顏色的感知。如果沒(méi)有標(biāo)準(zhǔn)的觀察池，那我們也可以在非直接照射的日光下觀看樣張。

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、照明的影響

2. Influence of lighting

當(dāng)我們?cè)诓煌恼彰鳁l件下觀察顏色的時(shí)候，看到的效果也是不同的。我們?cè)谟^察顏色時(shí)需要注意的另外一個(gè)問(wèn)題就是同色異譜。所謂“同色異譜”就是當(dāng)兩個(gè)樣張?jiān)谀撤N光源下，呈現(xiàn)的顏色是相同的，而在另外一種光源下，呈現(xiàn)的顏色則是不同的。

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.

在觀察顏色的時(shí)候，保持照明條件的穩(wěn)定一致是非常重要的。我們之所以會(huì)選用色溫為5000K的光源，主要是因?yàn)檫@種光源是由紅光、綠光和藍(lán)光混合而成的，能為人們提供穩(wěn)定一致的觀察環(huán)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、環(huán)境影響

3. Environmental impact

我們觀察印刷樣張時(shí)的周圍環(huán)境是否會(huì)對(duì)顏色產(chǎn)生影響?臨近色，也就是與被觀察的樣張或印張相近的顏色可以影響到人們對(duì)顏色的感知。

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.

這就是所謂的“臨界效應(yīng)”，它在一定程度上反映了在觀察樣張時(shí)使用中性環(huán)境的重要性。據(jù)了解，在周圍環(huán)境中使用標(biāo)準(zhǔn)灰色漆(MunsellN8)可有效減少人們?cè)诖_認(rèn)色彩時(shí)所受的鄰近色的影響。

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、紙張

4. Paper

減色法是指在白色環(huán)境中(通常是紙張)用黃、品紅、青和黑色油墨來(lái)混合成色的方法。在這個(gè)顏色復(fù)制過(guò)程中，有一個(gè)元素會(huì)對(duì)顏色的上機(jī)印刷效果產(chǎn)生重大影響，那就是紙張。

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.

同樣的墨色可能會(huì)在不同的紙張上產(chǎn)生不同的印刷效果。紙張?jiān)桨祝茉谟∷C(jī)上復(fù)制出的色域就越大。如果紙張的白度不夠，那么它在印刷機(jī)上復(fù)制出的色域就比較小。

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.

印刷不是一個(gè)完全匹配的過(guò)程，這主要因?yàn)樵陬伾珡?fù)制過(guò)程中有很多顏色復(fù)制系統(tǒng)。攝影就是一個(gè)典型的顏色復(fù)制系統(tǒng)，打樣和印刷也是如此。更多相關(guān)印刷包裝的事情就來(lái)我們網(wǎng)站http://buiy.cn咨詢吧！

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://buiy.cn Ask!
