Abstract:
1. A screen printing method of printing a pattern of paste on the surface of a printing medium which is positioned with respect to a mask having predetermined pattern holes therein, the screen printing method comprising the steps of: holding the printing medium on a top surface of a holding means comprising a carrier formed of a porous material disposed on top of the holding means; sucking through the porous material of the carrier the printing medium on the top surface of the carrier by vacuuming the carrier; lifting at least two mask supporting means, the at least two mask supporting means being disposed horizontally at the same height, a side surface of each of the at least two mask supporting means being horizontally facing each other across the holding means; supporting the mask by the at least two mask supporting means from the rear surface of the mask; bringing whole surface of the printing medium into contact with the rear surface of the mask between the at least two mask supporting means in a posture parallel to the mask by lifting the holding means after ensuring the posture of the printing medium is parallel to the rear surface of the mask, the holding means holding the printing medium; printing a pattern on the surface of the printing medium; changing the posture of the printing medium into a posture tilted relative to the mask so as to separate a part of the printing medium from the mask; and separating the printing medium completely from the mask by lowering the holding means such that lowering speed is set to be slower when the holding means starts lowering than when the holding means is on its way down.
