PROBLEM TO BE SOLVED: To provide a screen printing system which is space-saving and low-cost and capable of safely conducting screen printing with either of an ultraviolet-curing type ink and a solvent ink, or an ultraviolet ray device fitted to the screen printing system. SOLUTION: The screen printing system 1 is equipped with a screen printing machine 2 which is capable of conducting two kinds of screen printing with the solvent ink and the ultraviolet-curing type ink, a thermodrying oven 3 which is capable of drying the solvent ink with heat, a delivery conveyor 4 which is capable of conveying a printed object A to the thermodrying oven, and the ultraviolet ray device 5 which is fitted to be capable of irradiating the top side 4a of the delivery conveyor 4. The ultraviolet device 5 is equipped with a black light implement 7 having an exhaust port 6 and with an irradiation box 8 which houses the black light implement 7 and has an irradiation opening 8a enabling outward radiation of ultraviolet rays radiated from the black light implement 7. The irradiation opening 8a of the irradiation box 8 is provided with a transmission plate 12 formed of silica glass. COPYRIGHT: (C)2007,JPO&INPIT
