济南印刷厂如何做好颜色处理?

来源:http://www.jindingyinshua.com   日期:2021-02-24

济南印刷厂随着社会的发展,其发展空间越来越大,当我们在印刷的时候颜色的地位是非常高的,而工作人员需要具备颜色处理的方法,下面就给大家介绍一下做好颜色的处理:
With the development of society, Jinan printing factory has more and more space for development. When we are printing, the position of color is very high, and the staff need to have the method of color processing
一、在胶印中
1、 In offset printing
1、压力的大小直接决定了印刷过程中油墨的转移,如果印刷过程中出现局部的压力不均,将导致印刷墨色的不实。
1. The size of the pressure directly determines the ink transfer in the printing process. If there is local uneven pressure in the printing process, it will lead to the printing ink color.
2、橡皮布的压缩变形是产生压力的根本保证,油墨的转移就是橡皮布压缩变形的结果。因此,压力的大小及均匀程度与胶印印刷用的橡皮布有着直接关系。
2. Blanket compression deformation is the fundamental guarantee of pressure, ink transfer is the result of blanket compression deformation. Therefore, the size and uniformity of pressure and offset printing blanket has a direct relationship.
3、包覆在滚筒上的橡皮布,同时受到本身张紧力和压力的作用,随着滚压次数的不断增加,橡皮布压缩变形的应力积累,橡皮布会变得硬挺,失去原有的柔软性和高弹性,甚在橡皮布表面会出现光亮或龟裂的痕迹,从而导致压力的局部不均匀。
3. The blanket wrapped on the drum is affected by its own tension and pressure at the same time. With the increase of rolling times, the stress accumulation of blanket compression deformation, the blanket will become stiff, lose its original softness and high elasticity, and even appear bright or crack marks on the blanket surface, resulting in local uneven pressure.
4、由于橡皮滚筒安装在印版滚筒和压印滚筒之间,橡皮布上的每个微小单元每旋转一周,都要分别和两个滚筒各接触一次。
4. Because the rubber cylinder is installed between the plate cylinder and the impression cylinder, each tiny unit on the blanket has to contact with the two cylinders respectively once every rotation.

5、其受力是周期性变化的,正是由于橡皮布受力的周期性变化,会导致橡皮布产生内耗,导致橡皮布的老化,影响印刷压力的均匀性,可能导致橡皮布的报废。
5. The stress changes periodically. It is precisely because of the periodic change of the stress of the blanket that the blanket will produce internal friction, lead to the aging of the blanket, affect the uniformity of the printing pressure, and may lead to the scrap of the blanket.
6、橡皮布除了为胶印提供印刷压力外,橡皮布在压印力的作用下,应具有很好的将印版图文部分的油墨传递到承印物表面的能力,即受墨和释墨能力,但是橡皮布的老化会改变这种油墨传递的能力,也会导致墨色不实的现象。
6. In addition to providing printing pressure for offset printing, the blanket should have a good ability to transfer the ink from the graphic part of the printing plate to the substrate surface, that is, the ability to receive and release ink. However, the aging of the blanket will change the ability to transfer the ink and lead to the phenomenon of false ink.
二、印刷过程中
2、 During the printing process
1、出现墨色不实的原因很多,其涉及的因素也很多,包括纸张的性能、油墨的性能、印版的质量、印刷橡皮布 的质量、印刷压力、印刷机的性能和印刷工艺等方面。
1. There are many reasons for false ink color, including paper performance, ink performance, printing plate quality, printing blanket quality, printing pressure, printing press performance and printing process.
2、如果纸张、油墨的性能稳定,印版制作质量满足了印刷要求,印刷机工作性能相对稳定的话,还是出现了墨色印刷不实现象,其主要产生的原因就是印刷压力的问题了。
2. If the performance of paper and ink is stable, the quality of printing plate meets the printing requirements, and the working performance of the printing press is relatively stable, the ink printing is not true. The main reason is the printing pressure.
三、在平版胶印过程中常会碰到颜色印不实的现象,在印刷品上主要表现为印品实地部分有斑点或发虚,图文或线条残缺不全,图像的阶调层次再现性差或网点丢失。
3、 In the process of offset lithography, we often encounter false color printing. On the printed matter, it is mainly manifested as spot or void in the field part of the printed matter, incomplete graphics and lines, poor reproducibility of image gradation or dot loss.
济南印刷厂是以粉饰、识别、宣传商品为主要目的而采用的印刷方式和印后加工处理技术,而对于颜色的选择、管理、处理都是不可马虎的,认认真真的处理才能减少墨色不实的现象。希望以上内容对您有所帮助,如您想要了解更多精彩内容请点击官网:http://www.jindingyinshua.com
Jinan printing factory is to whitewash, identification, publicity of goods as the main purpose of the printing method and post press processing technology, but for the color selection, management, processing are not careless, serious processing can reduce the phenomenon of false ink.
