PURPOSE:To enhance resistance to chemicals and solvents in the cleaning of a screen and resistance to wear in the squeegeeing of the screen, by a method wherein a strong resin protective film made of a composition of an electron ray-curing or ultraviolet-curing acrylate resin or unsaturated polyester resin is provided on the both faces of cross portions of a gauze and a photosensitive film corresponding to non-image areas. CONSTITUTION:A photosensitive film 4 is uniformly formed by coating from one side of a gauze 2. The photosensitive film 4 is formed not only on the coating face side of the gauze 2 but also on the reverse thereof slightly. After the photosensitive film 4 is coated and dried, pattern elements 5 of an original picture are so formed as to be in close contact with the surface of the photosensitive film 4 to be exposed by an ultraviolet lamp 6. After the exposure, the photosensitive film is developed so that the unexposed portions are removed. On the gauze 2, image areas 7 and non-image areas 8 are formed. The photosensitive film is dried, thereafter being coated with a composition 9 of an electron ray-curing or ultraviolet-curing acrylate resin or unsaturated polyester resin on the both faces thereof. After the coating, the resin composition of the image areas 7 is removed; in this case, the resin applied only to the image areas 7 is partially allowed to remain on cross portions 10 of the gauze 2. The resin composition 9 coated on the both faces of a screen 1 is irradiated with an electron rays source or ultraviolet light source 11 for curing. |
