印刷宣传单页如何预防油墨晶化的故障!
作者:admin 来源:http://www.sdhzyw.com 发布时间:2019-7-2 16:48:24 浏览次数:244
油墨晶化是宣传单页印刷中的过程常出现的一种毛病,把我们有没有什么办法避免和预防呢?下面我们一起来看看济南宣传单页印刷给我们总结的几条方法!
Ink crystallization is a common problem in the process of Publicity sheet printing. Is there any way to avoid and prevent it? Next let's take a look at some methods of Jinan publicity leaflet printing to summarize for us!
1、用含有较多溶剂的快干型油墨罩印(不等它干透就印第二色,效果虽较好,但这种方法费工费时费料,成本高),使用的溶剂能浸入和软化底下一层的油墨膜层(但有时也会无济于事)。
1. Cover printing with fast-drying ink containing more solvents (printing the second color without drying it thoroughly, although the effect is better, but this method is time-consuming, material-consuming and cost-effective), and the solvent used can immerse and soften the ink film of the bottom layer (but sometimes it will be useless).
2、掌握套印时间,在前一色印刷后应当尽可能快地印刷第二道色。
2. Master the overprint time and print the second color as quickly as possible after the first color.
3、在油墨中加入一些延缓干燥的助聚剂(例如对苯二酚)或慢干材料(凡士林、羊毛脂、蜡助剂)。
3. Adding some retarding polymer additives (e.g. hydroquinone) or slow-drying materials (vaseline, lanolin, wax additives) to the ink.
4、在包装印刷装潢的图案设计上可采用不同的易于套印的基色。
4. Different basic colours which are easy to overprint can be used in the design of packaging, printing and decoration.
5、在油墨配方里应少用钴类干燥剂。
5. Cobalt desiccants should be used less in ink formulation.
6、可采用干燥快的合成树脂型连结料,以降低油墨中干燥剂的用量。
6. Fast-drying synthetic resin binder can be used to reduce the amount of desiccant in ink.
7、增强第二色墨的附着力,其目的就是破坏已晶化的墨膜。如采用零号调墨油或醇酸树脂、环氧树脂和聚酰胺树脂是附着力较大的材料,加入油墨中可以增强其附着力,但这些树脂与胶印油墨的混溶性不好,不能多加,因过多的加入往往会冲淡印刷油墨的颜色,而过少其效果又不会好。

7. The purpose of enhancing the adhesion of second color ink is to destroy the crystallized ink film. For example, zero toner ink or alkyd resin, epoxy resin and polyamide resin are the materials with high adhesion, adding ink can enhance its adhesion, but these resins and offset ink miscibility is not good, can not be added, because too much addition often dilutes the color of printing ink, and too little effect will not be good.

8、在印刷油墨中加入有机溶剂以溶解已晶化的墨膜层。这是印刷操作工常用的方法之一,但晶化的墨膜层已成为主体网状结构的光滑墨膜层不易被溶解,太多时效果不佳。
8. Adding organic solvent to printing ink to dissolve the crystallized ink film. This is one of the common methods used by printing operators, but the crystallized ink film has become the smooth ink film of the main reticular structure, which is not easy to dissolve, and the effect is not good when there are too many.
9、在印刷油墨中加碱或肥皂来增强极性,使较容易印刷上,但当时虽似印上了,而干后却附着不牢又极容易擦掉。
9. Adding alkali or soap to printing ink to enhance polarity and make it easier to print, but at that time, although it seemed to be printed, it was hard to adhere and easy to erase after drying.
综观以上处理方法及预防措施,能够保证包装印刷图文质量的是印刷中要掌握油墨的干燥度,以不让油墨成膜干过头就开始印第二道颜色为更佳。
Overview of the above treatment methods and preventive measures, to ensure the quality of packaging printing pictures and texts is to grasp the dryness of ink in printing, so that the best way is not to let the ink film dry too much and start printing the second color.
