A UV printer is a type of digital printer that uses ultraviolet (UV) light to cure or dry the ink as it is printed. Unlike traditional printing methods, UV printers can print directly on a wide range of materials, including plastic, glass, metal, wood, and acrylic. The UV-curable inks are exposed to UV light, which instantly hardens the ink, producing vivid, durable, and scratch-resistant prints. UV printers are commonly used for signage, promotional items, packaging, and custom products.
