How to solve the phenomenon of hair pulling in screen printing mesh?

Screen printing meshs are often used by us, and the phenomenon of paper fluffing sometimes occurs in the world's operation printing process. So how to solve the hairiness phenomenon?

The suggested steps are as follows:

1. Screen printing requires the characteristics of equipment and printed products. Choose a paper with a suitable surface strength.

2. Add ink or detackifier to the ink to reduce the viscosity and viscosity of the ink. This is the most commonly used method when printing paper with poor surface strength.

The fuzzing phenomenon is also exacerbated as the viscosity of the ink is increased. The viscosity of the ink has a significant effect on temperature. So when we operate, the workshop needs to maintain a certain temperature. Let the workshop have an ideal environment.

3. When the strength of the printing surface is not very good, the speed of printing should be controlled. If the printing speed is higher, the greater the tension when the paper and the blanket are peeled off, the easier it will be to pull. Surface fiber of paper

The binding force of fillers is large or small, not uniform, and the bonding strength of some particles and fibers is small. Therefore, when the printing speed is not very large, the brushing phenomenon occurs, but it is not serious.

The bonding strength of most particles or fibers is equivalent. Only when the printing speed is higher than a certain critical point and the peeling tension reaches a certain level, will the relatively serious hairiness occur.

4. Replace the blanket, or use talc to mix sulfur powder to wipe the blanket. Reached to reduce its stickiness. The phenomenon of pilling occurs during printing, which is caused by the stickiness of the blanket. When printing on paper with poor surface strength, you can use a monochrome machine to print, which can reduce the phenomenon of fluff and will not affect normal production.
