刷における段取り時間の短縮を図り得る。(Effects of the Invention) As described above, according to the plate matching method in the screen printing apparatus of the present invention, the screen is pressed by the squeegee against the printing object, and the paste is attached to the printing object by the movement of the squeegee. A plurality of cross marks for plate alignment are formed on the screen at the same time as the printing pattern in a fixed positional relationship, and an X is placed on the printed material.
-The optical system of the camera is fixed to the part of the Y-θ table that is off the printed material in correspondence with the plurality of cross marks for plate alignment, and the optical system has a fixed positional relationship with the printed material. Then, copy the cross mark for plate alignment with the camera and project it on the screen of the TV monitor,
The relative positional relationship between the screen and the printing object is corrected by the XY-θ table so that predetermined mutually orthogonal reference lines and the cross mark for plate alignment are superposed on the screen. Therefore, the positional relationship between the print pattern formed on the screen and the substrate to be printed can be made constant, and the plate alignment can be easily performed, and the setup time in screen printing can be shortened.
