description	The utility model provides a printing net which is applied to printing of light emitting diodes, the steel net is a block-shaped flat plate, a plurality of through holes penetrating through the uppersurface and the lower surface of the flat plate are formed in the flat plate, and the hole diameters of the through holes are gradually increased in the direction from the upper surface to the lower surface of the flat plate. Therefore, the through holes of the steel mesh are arranged to be large in bottom and small in top, the problem that glue and solder paste cannot be demolded is avoided to agreat extent, the success rate of LED installation is improved, and then the LED printing yield is improved. 本实用新型提供一种印刷网，应用于发光二极管的印刷，所述钢网为块状平板，且所述平板上开设有若干个贯穿所述平板的上表面和下表面的过孔，所述过孔的孔径沿所述平板的上表面至下表面的方向逐渐增大。从而通过将钢网的过孔设置为下大上小，很大程度上避免了胶水和锡膏不脱模的问题，提升了LED安装的成功率，进而提升了LED印刷良品率。
