PROBLEM TO BE SOLVED: To correct the discordance with a block copy by dividing a screen frame into a plate frame having a screen plate and a plate frame for supporting a plate frame body, and moving the body to the plate frame. SOLUTION: A plate body 12 having a screen plate 15 is detachably mounted in an auxiliary frame 13 in a screen printer, and the frame 13 is disposed in a plate frame 14. The frame 13 and body 13 are moved in synchronization with the movement of the frame 14, and when the frame 14 arrives at a print finishing point, a CPU controls first and second servo motors 35, 36 so that the frame 13 arrives at the set moving amount. Thus, the correction value for correcting the elongation or contraction in the printing direction at the time of printing is uniformly distributed to eliminate the printing failure due to the elongation or contraction. |
