The solution method to prevent the emergence of jagged wool

① Choosing the high mesh count mesh;

② Choosing the high sensitivity photosensitive material to making plate;

③ Making a certain thickness of the screen printing plate to reduce the expansion of deformation ;

④ Using oblique Stretching method to Stretching, the best angle is 22.5°;

⑤ For fine line printing, it is better to use indirect plate making method to make plate;

⑥ In the plate making and printing process, try to control the temperature expansion factor, and use the small expansion coefficient of photosensitive material;

⑦Improve the quality of plate making to ensure the screen printing plate surface is smooth and smooth, the edge of the screen lines must to be neat;

⑧ Using the spray gun to spray screen printing plate to improve the development effect;

⑨ The distance between the screen and the printed material, the scraper angle and the pressure should be appropriate.
