In the ordinary printing process, we often have the phenomenon of flying ink. What is the reason for this? Now, follow Jinan printing factory to see the reasons for the phenomenon of flying ink!

1、印刷時(shí)，空氣相對濕度小，促進(jìn)飛墨產(chǎn)生，濕度加大時(shí)，電荷減少，飛墨量變小。

1. When printing, the relative humidity of air is low, which promotes the production of flying ink. When the humidity increases, the charge decreases and the amount of flying ink decreases.

2、如果油墨中潤版液太多，黏度急劇下降，墨絲變短，會產(chǎn)生嚴(yán)重的飛墨現(xiàn)象，同時(shí)，浸入油墨的潤版液還會腐蝕金屬墨輥，在墨輥表面形成親水層而排斥油墨，造成金屬墨輥脫墨。

2. If there is too much fountain solution in the ink, the viscosity will drop sharply, and the ink filament will become shorter, which will cause serious ink flying phenomenon. At the same time, the fountain solution immersed in the ink will also corrode the metal ink roller, forming a hydrophilic layer on the surface of the ink roller and repelling the ink, causing the metal ink roller deinking.

3、墨輥上墨層越厚，飛墨越大。遇到紙張性能對油墨黏附力不好的情況，就容易造成墨輥堆墨，從而產(chǎn)生飛墨現(xiàn)象。

3. The thicker the ink layer on the roller, the larger the flying ink. Encounter paper performance on the ink adhesion is not good, it is easy to cause ink roller pile up, resulting in flying ink phenomenon.
                                

4、高分子量油墨的連結(jié)料，在油墨分裂時(shí)容易拉成長絲，產(chǎn)生飛墨。

4. The binder of high molecular weight ink is easy to be drawn into filament when the ink splits, resulting in flying ink.

5、油墨黏度過大，油墨在墨輥出口處被拉長，易產(chǎn)生飛墨，同時(shí)還會造成傳墨不勻，使紙張拔毛脫粉，紙張從橡皮布上剝離困難、易花版、掉版等，黏度過小，墨層分裂不佳，也容易產(chǎn)生飛墨，同時(shí)容易使油墨乳化、糊版、網(wǎng)點(diǎn)擴(kuò)大，影響印刷產(chǎn)品質(zhì)量。

5. If the ink viscosity is too high and the ink is elongated at the outlet of the ink roller, it is easy to produce flying ink. At the same time, it will cause uneven ink transfer, which will make the paper hairy and powdery. It is difficult for the paper to peel off from the blanket, and it is easy to print and drop. If the viscosity is too low and the ink layer is not well split, it is also easy to produce flying ink. At the same time, it is easy to emulsify the ink, paste the plate and expand the dot, which will affect the quality of printing products.

另外，墨輥表面凹凸不平及表面干結(jié)龜裂時(shí)，部分油墨層加厚，墨霧量加大，也是產(chǎn)生飛墨現(xiàn)象的因素之一，還需要我們注意的是，在印刷時(shí)，要控制印刷的速度，如果速度過快，造成飛墨現(xiàn)象的幾率就會更高。

In addition, when the roller surface is uneven and the surface is dry and cracked, part of the ink layer is thickened and the amount of ink mist is increased, which is also one of the factors causing the phenomenon of flying ink. We also need to pay attention to that when printing, we should control the printing speed. If the speed is too fast, the probability of causing the phenomenon of flying ink will be higher.
