印刷厂在印刷过程中，对油墨的要求非常的高，主要是因为它决定了印刷效果，而我们在使用的时候经常容易出现接皮现象，下面济南印刷厂就给大家介绍一下出现这种现象的原因：

Printing factory in the printing process, the ink requirements are very high, mainly because it determines the printing effect, and we are often prone to skin phenomenon when using, Jinan printing factory will introduce the reasons for this phenomenon:

1、油墨中的连结料组分能够和空气中的氧发生氧化还原反应，于空气中暴露时间过长当然就会被氧化，出现结皮现象。

1. The binders in the ink can react with oxygen in the air, which will be oxidized if exposed in the air for a long time.

2、墨辊结构不好，产生不流动的滞留部分。

2. The structure of ink roller is not good, resulting in stagnant part.

3、在墨斗中如果长时间不搅拌，会出现结皮现象：

3. If the ink bucket is not stirred for a long time, there will be skinning

在印刷过程中我们常讲"三勤"其中勤搅墨斗中的墨便是很重要的一项，它能够维持墨斗中油墨很好的流动性，其次这样做能够使表层的和内部的经常的交换，避免和空气接触的油墨总是同一部分。

In the printing process, we often talk about "three diligence". Among them, frequently stirring the ink in the ink bucket is a very important one. It can maintain the good fluidity of the ink in the ink bucket. Secondly, it can make the surface and interior exchange frequently, and avoid that the ink in contact with the air is always the same part.
                                          

4、印刷机长时间停机时：

4. When the printer stops for a long time:

①没有清洗墨路，造成在墨辊和墨斗中结皮，在工作中一定注意当较长时间停机的时候要将墨路清洗干净，当停机时间不是很长的时候，可以选择在墨路上喷涂防结皮剂。

① If the ink path is not cleaned, it will cause skin formation in the ink roller and ink bucket. In the work, pay attention to clean the ink path when it is shut down for a long time, and spray anti skin agent on the ink path when it is not shut down for a long time.

②暂时不用的裸露在空气中放置，时间一长表面就会出现厚厚的氧化膜。我们在印刷厂都会有这样的经验，当从墨盒或是墨桶中向外盛墨的时候。

② Temporarily not exposed in the air, a long time, the surface will appear thick oxide film. We all have this experience in printing factories, when filling ink from the ink cartridge or ink bucket.

5、要尽量的将表面保持一个平的状态，这样做的道理就是尽量减少油墨和空气的接触面积，这样即使结膜后浪费也会尽可能的小。

5. To keep the surface as flat as possible, the reason is to minimize the contact area between ink and air, so that even after conjunctiva waste will be as small as possible.

6、再就是将剩下的用保护膜重新盖上，阻断与空气的接触，这样也能很好的防止的结皮现象。

6. Then the rest is covered with protective film again to block the contact with the air, which can also prevent the skin formation.

印刷厂刚开始做印刷的时候经常出现油墨结皮的现象，所以我们大家在今后加工过程中要采取防止结皮的方法，生产质量提高了，会有很多客流量，从而我们的经济效益和收益也就提高了。

At the beginning of printing, the phenomenon of ink crusting often occurs in printing plants, so we should take measures to prevent ink crusting in the future processing process. With the improvement of production quality, there will be a lot of customers, so our economic benefits and income will also be improved.
