A UV printer is a device that uses ultraviolet curable ink for printing. The ink used by the UV printer contains a special ultraviolet curing agent. After the ink is ejected onto the printing medium from the print head, it will be quickly solidified and dried through ultraviolet irradiation, allowing the image to be formed immediately. The V printer is suitable for various types of printing media, including but not limited to paper, plastic, glass, ceramics , metal, wood, leather, etc. It can be printed on flat and curved surfaces to achieve personalized customization on a variety of materials.
