Method for movably improving overprinting of screen printing plate

The invention belongs to the technical field of screen printing plate overprinting, and particularly relates to a method for movably improving screen printing plate overprinting. A screen frame is mounted on the inner side wall of the plate frame; sliding grooves are formed in the two ends of the plate frame. Sliding blocks are slidably connected to the inner side walls of the sliding grooves, so that the plate frame and the screen frame are clamped and fixed, the plate frame and the screen frame are tightly attached, when paper is overprinted and the fixing and clamping position needs to be adjusted, clamping handles are pressed to enable clamping rods to drive clamping plates to be opened, the positions of the clamping rods and the clamping plates are adjusted through guide rods, and therefore the paper is overprinted. According to the paper overprinting device, a worker can conveniently clamp and fix the paper in all directions, the problems that the paper is affected by the humidity of the plate frame and
