油墨在印刷中有著非常重要的作用,要知道油墨在印刷中使用有很多問題是需要大家去注意的,下面就由濟南彩色乐天堂fun88体育的客服人員給大家說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、別混用
1. Don't mix it up
水性油墨不能與其他溶劑油墨混用,否則,導致質量問題。
Water-based ink can not be mixed with other solvent ink, otherwise, it will lead to quality problems.
2、添加相應助劑
2. Adding corresponding additives
由于醇和胺都易揮發,因此,油墨的PH值容易發生變化,在印刷過程中要注意經常添加相應的助劑。
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、控制好干燥溫度
3. Control drying temperature

水性油墨以揮發干燥為主,并配有一定反應干燥,干燥墨膜的復溶性比溶劑型油墨差。因此,熱空氣溫度控制很重要,溫度太低油墨表層干結,但內部干燥不透,套色時出現反粘;溫度太高油墨干燥速度快,干結墨層無法再溶解于水,清潔困難。

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、適當淺版化
4. Appropriate shallow Edition
一方面,水性化體系導致油墨具有牛頓流體的流變特征,傳墨量比溶劑型油墨大15%以上;另一方面,水性油墨的固體含量高,相同面積干燥墨膜厚度可小一些。因此,對相同表面積的著墨孔,建議雕刻得淺些。
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、加入消泡劑
5. Adding defoamer
水性油墨呈弱堿性,印刷過程中比溶劑型油墨更容易產生氣泡,在印品上出現白點、砂眼等質量故障,因此可加入1%左右的消泡劑。
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.
