A method for producing a printing screen that guides ink and increases ink penetration, including the following steps: weaving a plurality of warp threads and a plurality of weft threads in an up-and-down manner to form a mesh; the warp threads and the The equal weft is stretched with a predetermined tension and fixed on a net frame; the net cloth is covered by at least one material to form a material layer on the net cloth, wherein the net cloth includes a scraper surface and a sticker The printing surface; the material layer is etched by a laser etching method to form a plurality of squeegee surface opening patterns and a plurality of printing surface opening patterns on the material layer, wherein each of the squeegee surface opening patterns includes a squeegee surface pattern opening Width, a first squeegee surface opening pattern edge and a second squeegee surface opening pattern edge, each of the printing surface opening patterns includes a printing surface pattern opening width, a first printing surface opening pattern edge and a second sticker The edge of the printing surface opening pattern, and the opening width of the squeegee surface pattern is made larger than the opening width of the printing surface pattern by the laser etching method; and the squeegee surface opening pattern is etched by the laser etching method or another etching method, so that The edge lines of the first squeegee surface opening pattern edge and the second squeegee surface opening pattern edge are non-linear lines, and the laser power and time of the laser etching method are controlled to make the first printing surface opening pattern edge And the edge line shape of the edge of the opening pattern of the second printing surface is a straight line, wherein, in the step of making the edge lines of the first squeegee surface opening pattern edge and the second squeegee surface opening pattern edge non-straight lines, Further by the laser etching method, the edge lines of the first squeegee surface opening pattern edge and the second squeegee surface opening pattern edge are one of a plurality of triangular lines, a plurality of semicircular arc-shaped lines, or a plurality of quadrilateral lines . For example, the method for manufacturing a printing screen that guides ink and increases ink permeability of claim 7, wherein, in the step of covering the mesh with the at least one material to form the material layer on the mesh, The scraper surface of the mesh cloth is further covered by a first sub-material to form a first sub-material And the printing surface of the mesh cloth is covered with a second sub-material to form a second sub-material layer. The first sub-material layer and the second sub-material layer constitute the at least one material layer. For example, the method for manufacturing a printing screen for guiding ink and increasing ink permeability of claim 8, wherein the first sub-material layer is a photosensitive emulsion layer, and the second sub-material layer is a polymer material layer. For example, the method of manufacturing a printing screen for guiding ink and increasing ink permeability of claim 7, wherein when the laser etching method is used to make the edges of the opening pattern on the first squeegee surface and the edge of the opening pattern on the second squeegee surface When the edge lines are the triangular lines, the angle of each of the triangular lines pointing to one of the opening patterns of the scraper surface includes an included angle, and the included angle is any angle between 30 degrees and 90 degrees. For example, the method for manufacturing a printing screen that guides ink and increases ink penetration of claim 10, wherein the included angle is one of 30 degrees, 45 degrees, 60 degrees, or 90 degrees. For example, the manufacturing method of the printing screen for guiding the ink and increasing the ink permeability of claim 7, wherein the opening width of the squeegee surface pattern is 50-600 μm.
