Countermeasures: Check whether the job design contains the problem of white shrinkage, re-calibrate the white, check the calibration parameters and the height of the nozzle base plate, pay attention to the setting of white ink temperature and voltage, and prevent the ink-jet from being straight and the amount of ink is too much.
Solution: Adjust the printing parameters to the appropriate state (such as single and double direction Settings), ensure that the horizontal calibration parameters are accurate, check whether the spacing between the nozzle and the printing material is moderate, avoid excessive printing deviation, and recalibrate the X-axis motion coefficient to optimize the motion accuracy.
Treatment: Re-examine and adjust the calibration parameters to ensure that the white and color nozzle calibration is accurate, and check the distance between the nozzle base plate and the printing medium to ensure the overprint quality.
Solution: Clean the surface of the medium, use alcohol to remove impurities, for specific materials such as PP, you can try to coat special materials to enhance adhesion; For metal or glass, apply special coatings; Enhance the UV lamp irradiation intensity and improve the adhesion by adjusting the light mode.
Solution: Eliminate static electricity in the media, adjust the humidity of the operating environment, and check and adjust the sprinkler voltage to a proper range.
Optimization method: First, select an appropriate configuration file and fine-tune RIP parameters (including print passes, resolution, etc.). Then, review and adjust the print mode parameters, such as speed, one-way, pass, light mode, and white ink parameters.
Repair steps: First, make sure that the secondary ink cartridge is sufficient. Secondly, check the amount of ink in the main cartridge and replenish it in time. Then, respond to the software ink feed prompt to ensure that you choose to continue the ink supply. Finally, the ink shortage state is simulated, the ink pump function is tested, the nozzle is cleaned regularly, and the negative pressure is adjusted to the appropriate range.
Adjustment strategy: Check calibration parameters (such as step, Y deviation) to ensure accuracy; Check whether the data transfer is stable, reinsert the USB port, and restart the device and software to rectify the data transfer exception.
Solution: First, adjust the negative pressure value to the ideal state. Clean the ink on the surface of the nozzle, and wipe it carefully after pressing the ink. Then, exhaust the nozzle and replace the filter to maintain the ink supply system.
When using UV flatbed printers, it is important to ensure the suitability of the operating environment and the quality of the ink. First of all, the choice of certified, market reputation good factory inks, especially those with a high degree of versatility, is a wise choice in the current industry, because most ink performance differences are not too great.
Regarding machine placement, careful consideration is required:
Adjust the ink level height according to the ink sac type to ensure that the negative pressure system works properly, neither too large nor too small to avoid poor ink supply or dripping ink.
Adjust the ink level height according to the ink sac type to ensure that the negative pressure system works properly, neither too large nor too small to avoid poor ink supply or dripping ink.
Check the status of the nozzle every day, once you find signs of blockage, immediately gently clean, avoid excessive force pumping ink, so as not to damage the nozzle. Correct pumping techniques, such as slowly drawing a small amount of ink after standing, and then flash spray test, can effectively extend the service life of the nozzle.In summary, pay attention to ink selection, environmental control, correct maintenance, especially to avoid strong light, dry, dust and improper operation, is the key to ensure the long-term and stable operation of UV flatbed printer nozzle.
