PURPOSE:To make it possible to economically form the support for a screen printing base plate wherein the size, shape and distribution of the perforated opening part are equal with each other, by forming a resin into a film in such a state that the liquid resin is present only in the recessed parts of a roll or an endless belt and releasing the resin film formed as an aggregate having a substantially closed shape. CONSTITUTION:An ultraviolet curable resin liquid 5 is applied to a roll 2 having recessed parts formed by etching a blank part so as to leave a pattern wherein substantially closed shapes are arranged independently in a closely contacted state. The adhered resin present other than the recessed parts is removed to allow the resin liquid 5 to be present only in the recessed parts and, in this state, the resin liquid is irradiated with ultraviolet rays from an ultraviolet irradiation apparatus 1 to be formed into a film. Thereafter, the resin film formed as an aggregate having a substantially closed shape is released from the roll 2. As a result, the support for a screen printing base plate wherein the size, shape and distribution of the perforated opening parts are equal with each other can be formed economically. |
