ABSTRACT:
A screen printing apparatus has a holder for a printing plate which includes a screen master composed of a thermoplastic synthetic resin film and a porous screen stuck together and an inner frame attached to the screen master on its film side. The holder includes a lower outer frame for supporting the printing plate on its inner frame side, and an upper outer frame pivotally movable relative to the lower outer frame for pressing the printing plate against the lower outer frame so as to clamp the inner frame between the upper and lower outer frames. The upper outer frame has a downwardly bent inner peripheral edge for pushing the screen master from its screen side as the printing plate is held between the upper and lower outer frames.
