The present invention provides a nano-ranged wide color gamut and environmental-friendly UV inkjet printing system for a hard substrate comprising a carrier, an ink supplier, a printing head and a controller. The carrier receives the hard substrate thereon and the ink supplier includes a container space for containing an ink. The color gamut of the ink comprises basic colors of RYBK. The printing head receives the ink from the ink supplier, and the controller generates a control signal to control the printing head to spray coating the ink onto the surface of the hard substrate directly. The present invention is able to print the ink directly onto the surface of the hard substrate while utilizing the UV light for curing the ink into solid. The ink exhibits the physical properties of low surface tension, nano particles, environmental friendly, UV excitable, short duration of drying, great adhesiveness and high transparency. |
