PURPOSE:To prevent the occurrence of printing defects such as a shift of a pattern and irregular color due to the slack of a screen after stretching and a shift of the screen at the time of printing. CONSTITUTION:When a screen 2 is stretched in a nearly rectangular plate frame 1, the frame 1 is divided into four frame parts 1a, 1b and at least the two frame parts 1a parallel to the longitudinal direction of the frame 1 are curved so that the centers of the frame parts 1a in the longitudinal direction are positioned outermost. The screen 2 can be pulled by the plate frame 1. |
