Flatbed printers are prone to ink flying due to improper operation during the working process. The flying ink will damage the appearance of our products and reduce the quality of the products. So in the daily operation process, how should we operate correctly to prevent the phenomenon of ink flying?
Reason 1: The nozzle of the uv printer equipment is disconnected
Solution: Print a test strip and check the condition of the nozzle. If it is found that it is blocked, it is empty, etc., it is necessary to clean the channel of the nozzle to keep it unobstructed.
Reason 2: The distance between the uv printer nozzle and the substrate is too high
The reasonable height is generally below 10cm, and the distance from the substrate to the substrate is between 1mm and 20mm due to the ejection force of different nozzles. If it exceeds the spray force range of the nozzle itself, it will cause the phenomenon of ink flying.
Solution: reduce the distance between the print head and the substrate.
Reason 3: Printer Electronic Control System
It is caused by the unreasonable pulse interval of the electronic control system to control the nozzle ignition.
Solution: need technical personnel to solve it.
Reason 4: The voltage of the uv printer nozzle is too high
The voltage displayed by the indicator light of the sprinkler board, whether the red light is on, alarm. If this happens, the voltage of the print head needs to be reduced.
Solution: If it is a modified circuit board, you need to change the circuit.
Reason 5: Static electricity generated during printing
When the environment is dry and the humidity is low, static electricity is easily generated, resulting in electrostatic influence between the nozzle and the material.
Solution: add ground wire, add static bar.
