彩色设计印刷的油墨在使用有什么要注意的?
作者:admin 来源:http://www.sdhzyw.com 发布时间:2019-8-8 17:04:39 浏览次数:69
油墨在印刷中有着非常重要的作用,要知道油墨在印刷中使用有很多问题是需要大家去注意的,下面就由济南彩色设计印刷的客服人员给大家说下使用油墨有什么需要注意的吧。
Ink plays a very important role in printing. We should know that there are many problems in the use of ink in printing that need to be paid attention to. The customer service personnel of Jinan color design and printing will tell you what needs to be paid attention to when using ink.
1、别混用
1. Don't mix it up
水性油墨不能与其他溶剂油墨混用,否则,导致质量问题。
Water-based ink can not be mixed with other solvent ink, otherwise, it will lead to quality problems.
2、添加相应助剂
2. Adding corresponding additives
由于醇和胺都易挥发,因此,油墨的PH值容易发生变化,在印刷过程中要注意经常添加相应的助剂。
Because alcohols and amines are volatile, the PH value of the ink is prone to change. In the printing process, attention should be paid to the frequent addition of corresponding additives.
3、控制好干燥温度
3. Control drying temperature

水性油墨以挥发干燥为主,并配有一定反应干燥,干燥墨膜的复溶性比溶剂型油墨差。因此,热空气温度控制很重要,温度太低油墨表层干结,但内部干燥不透,套色时出现反粘;温度太高油墨干燥速度快,干结墨层无法再溶解于水,清洁困难。

Water-based ink is mainly volatile drying, and it is equipped with a certain reaction drying. The resolvability of dry ink film is worse than that of solvent-based ink. Therefore, hot air temperature control is very important. Ink surface drying is too low, but the internal drying is impervious, and anti-sticking occurs when color matching. Ink drying speed is too high, and the dry ink layer can no longer dissolve in water, so it is difficult to clean.
4、适当浅版化
4. Appropriate shallow Edition
一方面,水性化体系导致油墨具有牛顿流体的流变特征,传墨量比溶剂型油墨大15%以上;另一方面,水性油墨的固体含量高,相同面积干燥墨膜厚度可小一些。因此,对相同表面积的着墨孔,建议雕刻得浅些。
On the one hand, the water-based ink has the rheological characteristics of Newtonian fluid, and the ink transmission is more than 15% larger than that of solvent-based ink. On the other hand, the solid content of water-based ink is higher, and the thickness of dry ink film in the same area can be smaller. Therefore, for the same surface area of ink hole, it is recommended to carve shallow.
5、加入消泡剂
5. Adding defoamer
水性油墨呈弱碱性,印刷过程中比溶剂型油墨更容易产生气泡,在印品上出现白点、砂眼等质量故障,因此可加入1%左右的消泡剂。
Waterborne ink is weak alkaline. It is easier to produce bubbles than solvent-based ink in the printing process. There are quality faults such as white spots and sand holes on the printing products. Therefore, about 1% defoamer can be added.
