PURPOSE:To improve plate release property in screen printing and pattern precision by adding external force in a direction to extinguish adhesion due to an ink in between a screen and a matter to be printed with movement to the screen. CONSTITUTION:External force applying sections 104-1 and 104-2 which add external force in a direction to extinguish adhesion between a screen 3 and a matter to be printed at the time of scanning of a squeegee 7 are arranged either at the matter to be printed on the face of the screen 3 or at the side of the squeegee 7. The external force applying sections 104-1 and 104-2 move on the screen 3 with the scanning of the squeegee 7. Accordingly, as a distance between the squeegee 7 and the external force applying sections 104-1, 104-2 is kept constant, the external force in the direction to extinguish the adhesion is added to the external force applying sections 104-1, 104-2 and component of the tension of the screen 3 in the vertical direction to the face of the screen 3 can be supplied uniformly, so that plate releasing can be done excellently and a uniform pattern can be formed stably.
