Abstract
A screen process printing plate includes a screen holding plate provided with an opening and having flexibility and restoring capability. A screen is fixed to the screen holding plate and covers at least a part of the opening. A fixed member is provided for fixedly holding one end of the screen holding plate and a movable member is provided for holding an opposite end of the screen holding plate. The movable member is movable in a direction parallel to a plane defined by the screen. A biasing device is provided for biasing the movable member in a predetermined first direction away from the fixed member and in the direction of movement of the movable member. When a squeegee presses the screen holding plate and the screen, the screen holding plate and the screen are flexibly curved easily into contact with an object to be printed. Since the tension is supported by the screen holding plate, excessive tension does not occur in the screen. The screen is snapped-off by the restoring force of the screen holding plate.
