PROBLEM TO BE SOLVED: To provide a method and an apparatus for screen printing whereby a complicated manual cramping power adjusting work and an advance work of entering the cramping data for every printing board into a controlling program can be eliminated to keep the printing circuit board automatically retained by the optimal cramping force for screen printing. SOLUTION: The method for screen printing, using a printing circuit board stress measuring device 30 of the apparatus for screen printing which detects the reactive force against the pressure by pressing the printing circuit board 24 from the surface side thereof, includes the printing circuit board reactive force measuring process wherein the reactive force of the printing circuit board 24 is measured by the printing circuit board reactive force measuring device 30, the cramping process wherein the printing circuit board 24 is cramped by the side cramping device 80 with the cramping force based on the measured value of the reactive force, the printing process wherein a printing agent is printed using the squeegee 10 by putting the screen mask 8 over the cramped printing circuit board 24.
