THE SCREEN PRINTING METHOD AND SCREEN PRINTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To offer the method of screen printing and the screen printing apparatus which prevent printing paste stuck on the squeegee nozzle tips from creeping around to the back-side of the nozzle and from the poor printing performance by which the printing screen being dragged and torn at the opening of the screen thus causing poor printing on the printing base plate. SOLUTION: When the printing process begins where the apparatus drops the squeegee 7 and the squeegee 8 from the predetermined stand-by position above the screen plate 4 down to the position to contact the screen plate 4, the squeegee 7 and the squeegee 8 are to move diagonally downward and contact the screen plate 4 in the direction opposite to the printing direction after the squeegees contact the screen plate 4. By this printing method, the apparatus diminishes the poor printing performances on the printing base plate 1 caused by the excessive printing paste 6 which creeps around to the backside of the squeegee 7 and squeegee 8.
