保证印刷过程中的中性灰平衡怎么做

来源:http://www.xinfengyinshua.cn/   发布时间:2022-09-30
中性灰平衡由于能够保证印刷过程中正确复制原稿的样式,所以非常重要。为保证印刷过程中的中性灰平衡,需要了解中性灰平衡的影响因素。下面济南印刷小编为您讲解一番。
Neutral gray balance is very important because it can ensure the correct reproduction of the original style during the printing process. In order to ensure the neutral ash balance in the printing process, it is necessary to understand the influencing factors of neutral ash balance. Now, Jinan Printing Editor will explain it to you.
先要搞清楚色彩的变化规律,三原色油墨按一定比例能混合近似黑色,再加上不同比例的冲淡剂,那么,得到不同颜色的中性灰。三原色以不同比例混合能得到不同色相的间色或复色,色相偏于比例大的色相。
First of all, we need to understand the law of color change. Three primary colors ink can be mixed with approximate black according to a certain proportion, and then with different proportion of diluents, we can get neutral gray of different colors. The three primary colors can be mixed in different proportions to obtain intermediate or multiple colors of different hue, and the hue is biased to the hue with large proportion.
纸张的性能与中性灰平衡关系,印刷企业的产品质量受原材料纸张影响较大,理想的纸张白度为100%的反射率,全反射380~700nm的光线。
The performance of paper is related to the neutral gray balance. The product quality of printing enterprises is greatly affected by the raw material paper. The ideal paper whiteness is 100% reflectivity, and the total reflection is 380~700nm.
在制版、印刷过程中就要考虑“因纸而异”,采用合适的工艺内容去适应所使用的纸张,尤其是在网点的粗细、套色的多少、版面反差大小等方面。
In the process of plate making and printing, it is necessary to consider "different from paper to paper", and adopt the appropriate process content to adapt to the paper used, especially in terms of the thickness of the dot, the number of overprinting, the size of the page contrast, etc.

印刷色序与中性灰关系,首先考虑到了让透明度低的油墨放在一色印刷,然后再印透明度高的油墨,这种色序排列是按油墨的透明度大小来排列的。
For the relationship between printing color sequence and neutral gray, it is first considered that the ink with low transparency is printed in one color, and then the ink with high transparency is printed. This color sequence is arranged according to the transparency of the ink.
同时还考虑到油墨粘度,可以避免印刷品背面粘脏现象;浅颜色放在前面印,清洗墨辊就很容易;也便于四色套印准确性。多色胶印机是湿叠湿,印刷油墨在没有氧化结膜干燥的情况下,另外一种颜色油墨又叠印上去了。
At the same time, considering the viscosity of the ink, it can avoid the sticky dirt on the back of the printed matter; Light color is printed on the front, and it is easy to clean the ink roller; It also facilitates the accuracy of four-color overprint. The multi-color offset press is wet and overlapped. When the printing ink is dry without oxidation conjunctiva, another color ink is overprinted.
不同的色序排列对中性灰平衡是有较大影响的,不同的色序会直接影响到印刷出来产品质量和色彩的色调。
Different color sequence arrangement has a great impact on neutral gray balance, and different color sequence will directly affect the quality of printed products and color tones.
在生产实际中要综合分析,把印刷工艺中涉及的一些可变因素考虑得再多一点,在色序排列上要根据不同类型的原稿、客户的要求印刷出来的效果进行安排色序,才能达到印刷品的很好的再现复制原稿的要求。更多相关内容就来我们网站http://www.xinfengyinshua.cn咨询吧!
In the actual production, comprehensive analysis should be made to consider more variable factors involved in the printing process. In terms of color sequence arrangement, color sequence should be arranged according to different types of originals and the effect of printing required by customers, so as to meet the requirements of reproduction of originals.
