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. 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. The structure of ink roller is not good, resulting in stagnant part.
3. If the ink bucket is not stirred for a long time, there will be skinning
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. When the printer stops for a long time:
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 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. 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. Then the rest is covered with protective film again to block the contact with the air, which can also prevent the skin formation.
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.
