[0002] UV printer is a special printing equipment, also known as ultraviolet curing equipment or UV curing equipment. Its main function is to use ultraviolet (UV) irradiation to quickly cure the photosensitive material applied to the printing material, thereby completing the printing process. This printing method was originally used for paper printing, but is now also widely used on various other materials, such as plastics, metals, ceramics, etc. UV printing has many advantages, such as rich colors, fast curing, environmental protection, etc., so it is widely used in various industries, including packaging printing, label printing, textile printing, etc.
