PROBLEM TO BE SOLVED: To prevent an error or a wrong judgement of a screen position recognition from occurring, to increase the workability efficiency of a printing, to prevent the surface of a solder from being oxidized, and to improve the mechanical or electrical performance of an article to be printed by preventing a cream solder from falling onto a screen, when a squeegee 8 is separated from a cream solder pool (m). SOLUTION: By this method, when the squeegee 8 separates from the cream solder pool (m), the squeegee 8 is relatively moved in the printing direction while being raised. When an angle formed by the trajectory n of a corner part 8a of the squeegee 8 and a screen S is taken asβ, and an angle formed by the squeegee 8 and the screen S is taken asα, by satisfyingβ≤α(αis preferably 60°), the corner part 8a of the squeegee 8 always rises in the W direction, along the cream solder pool (m) or while pressing the cream solder pool (m), and the cream solder is prevented from falling in.
