If the object to be printed on is transparent, it is necessary to shield it from light in order to prevent UV light reflected off the inside of the object from striking the print head surface. UV light striking the print head surface will harden the ink on this surface, leading to discharge issues. The shielding method depends on the object to be printed on. When adhering masking tape to the outside of the object to be printed on, avoid the rollers of the rotary axis unit.
