PURPOSE:To reduce unsatisfactory printing, by a method wherein a vibration proofing member is provided between a holder block holding a squeegee and a holding member supporting the holder block, and exciters imparting vibration to the squeegee in printing is mounted on the holder block. CONSTITUTION:A linear-motion actuator vertically driving a member built in a holding member 7 is securely installed to a fixed board 2 with a nut 3a. Simultaneously when the fixed board 2 starts traveling horizontally leftwards by a driver, the actuator 1 acts to move downwards, and the tip edge of a squeegee 17 moves leftwards while pressing down a screen 23. At this time, first and second exciters 19a and 19b are actuated. By the squeegee 17 a paste 26 travels and reduces in viscosity. Additionally, the vibration of the first and second exciters 19a and 19b reduces the viscosity of the paste 26, thus making the paste 26 easy to move downwards with the bubbles in the paste 26 eliminated. As a result, the paste 26 is printed on a matter to be printed 24 through the pattern of the screen 23. In this manner, by imparting the vibration to the squeegee 17, printing unsatisfactoriness is remarkably reduced, and production loss can be improved away to a great extent.
