What is the reason for the ink flying phenomenon in UV printers?

1. There is a relationship between the height of the flying ink and the nozzle, for example, when we change materials, the height of the nozzle is not adjusted to the optimal printing spacing.

2. It is related to indoor stability and humidity. For example, due to the influence and changes of temperature, yesterday's machine printing was normal, and today's printing may cause some ink flying.

3. It has a certain relationship with the state of inkjet, because UV ink itself is corrosive to the nozzle, and the nozzle is severely damaged. Poor state can also cause ink flying.

4. He has a certain relationship with the quality of UV ink, and some customers want to reduce our printing costs by replacing some cheaper and lower quality ink because the viscosity and composition of the ink are different, which can also cause ink flying to varying degrees.

5. The curve and waveform of UV ink itself are related.

6. It also depends on whether the material itself has static electricity, such as acrylic PVC panels. After tearing off the protective film, there will be some static electricity, which can also affect the flying ink.

7. It also depends whether the device has a grounding wire. The grounding wire is related to the export of static electricity. If static electricity cannot be exported well, ink flying may also occur during printing, which is a common phenomenon.
