uv flatbed printer print exists pass solution

        UV flatbed printers have a pass, which is theoretically unavoidable, and mechanical errors cannot be eliminated to zero. However, the higher the accuracy, the smaller the pass phenomenon, and the less it will affect the printing quality. The cause of the pass of the pattern: the print feathering is too low, the two-way printing is too fast, the Y-axis belt is loose, the nozzle is in a bad state, and the ink is broken.


       1.UV flatbed printer prints too low

       Solution: The turning on of feathering is to make up for the link between the ink dots in the UV flatbed printer during the printing process, so that the effect of the pattern is more natural. UV inks have very poor leveling properties, unlike water-based or solvent-based inks. When ink dots are sprayed on the material, they will naturally diffuse around. Due to the action of ultraviolet rays, UV ink will be cured immediately after the surface of the material. When viewed in this way with a magnifying glass, the gap between the ink dots and the ink dots is relatively large. You can turn on the feathering value at 80 or 100 to eliminate the pass phenomenon.

       2.UV flatbed printer is bidirectional printing and too fast

       Solution: Can be changed to unidirectional printing, which can meet high-precision printing. If the accuracy of the pattern is not high, you can select the two-way fast print mode.

       3.Y axis belt of UV flatbed printer is loose

       Solution: After the Y-axis belt of the UV flatbed printer runs for a long time, it will become loose. At this time, it only needs to be tightened and adjusted. If the y-axis is driven by a screw rod, remember to perform regular oil maintenance.

       4, UV flat printer nozzles are in bad condition, ink cut, etc.

       Solution: Pause the printing of the equipment, press the ink on the nozzle, and clean the cleaning liquid. When the sprayed cleaning liquid is found to be in the form of a beaded water, the nozzle holes have been cleaned, and printing can be continued.

       Suggestion: At the beginning of the daily printing of UV flatbed printers, test strips must be printed, and the state of the nozzles must be observed in time. Follow-up work should be performed after everything is OK.
