A method of manufacturing a screen printing plate which can be obtained without using a mother mesh sheet and a resist film including a step of providing a non-plating area on the roll and exposing the roll coated with high-sensitivity photosensitive film by a multiple number of laser beams. The multiple number of laser beams are controlled by preset electric data so that the desired halftone points of negative halftone image are exposed on the roll.
