1.Causes: The height of the print head from the material medium is too high, the ink dot landing point is greatly affected by external forces, and the landing point is not accurate, resulting in flying ink.
Solution: The height of the general nozzle and the material should be controlled between 1mm ~ 2mm
2.Causes: Static electricity. If the uv printer is in a low humidity and dry environment, it is easy to generate static electricity between the nozzle and the material, which will cause ink flying during the printing process.
Solution: add a ground wire or add an electrostatic bar (shielding static electricity), and add a humidifier.
3.Problem: The machine has been used for a long time, and the filter nozzle will be disconnected when the filter is blocked. This phenomenon will inevitably cause the machine to fly ink.
Solution: Print a test strip to check the status of the nozzle. If it is found to be clogged or falsified, the nozzle channel needs to be cleaned to keep it clear.
4.Causes: Different inks have different properties, and their viscosity may also cause flying ink. If some inks have poor fluidity and the voltage of the nozzle is very low, this situation may also cause flying ink.
Solution: It can be considered that the problem can be solved by increasing the nozzle correction voltage.
5.Cause: Environmental temperature problem. Temperature will affect the viscosity of the ink, which indirectly causes the problem of flying ink. If the temperature is too high, the viscosity of the ink decreases; if the temperature is too low, the viscosity of the ink increases.
Solution: Properly improve the ambient temperature, such as installing air conditioners in the workshop.
6.Cause: The frequency of the ignition of the nozzle controlled by the electronic control system is unreasonable.
Solution: The problem of the electronic control system, which needs special technical personnel to repair to solve.
7.Causes: rip software problems, such as rip curve problems, but the probability of flying ink caused by the curve is extremely low. If the flying ink is caused by the curve problem, it can only be done by professional technicians, which is more troublesome.
The above are reasons and solutions for flying ink of Skycolor UV flatbed printer.
