Abstract

The invention discloses a tension method of a printing polyester screen. By adopting the technical scheme, the tension method has the advantage that warp yarns, weft yarns and a screen framework of the screen are calibrated by films, so that the edges of the screen framework maintain the standard preset angle with the warp yarns or weft yarns of the screen, then the screen adhering and glue setting are performed, the difference between wave peak and wave valley of sawtooth after screen exposing is obviously reduced, the problem of sawtooth in screen and printing is greatly relieved, and the qualified rate in printing is improved.

Description

technical field [0001] The invention relates to the technical field of screen printing, in particular to a method for stretching a screen printing polyester screen. Background technique [0002] At present, domestic screen printing polyester screen production has a relatively high production level, but when producing high-precision polyester screens in batches, the angle of screen frame placement and the elongation characteristics of the screen after stretching still cannot approach the standard. The level of the predetermined angle (such as 45°), so that the tangent line of the edge of the pattern after printing is too much, and the tangent line is jagged (see figure 1 ), the jagged edges of the printed glass window lens can be seen with the naked eye, and the difference between the peak and the trough is too large when observed under a magnifying glass. state. Contents of the invention [0003] The main purpose of the present invention is to propose a method for stretc...
