As is well known to the industry, since the printed patterns are formed by mesh meshes, the quality of the cloth will directly affect the results of the printing. According to a long-term study by the inventors, the two disadvantages of exposure and correction of the weaving phenomenon and the mesh line displacement are that the printed pattern is inaccurate and incomplete. When the phase steel wire is woven into a mesh cloth, there is a silk in the exposed (four) off-face, which causes the light to refract. 'If the figure is good and the mesh is composed of three sides (ie, the pattern outline (four), the transverse wire interlaced part constitutes a triangular wear surface ), there is a lack of development incomplete during the development stage. On the other hand, since the longitudinal and transverse wire interlacing portions are not fixed at the time of printing by the printing machine, the blade is pulled to the wire to deform the pattern, and the weight cannot be made fresh. Improvement due to both financial and shortcomings.乩 [Summary of the Invention] In the above-mentioned shortcomings, the object of the present invention is to fix the cross-section of the horizontal and vertical wires of the mesh to the printed woven mesh cloth, so as to avoid the printing of the steel wire when the printer is running to the knife. problem. In order to solve the problem of the deformation of the conventional printed pattern, it is not invented that the purpose is to change the __color, the refracting, and the technical problem of incomplete development. ^ ^ 7 Ming is in the form of electroforming, the net cloth per horizontal and vertical wire crossing = set to increase the net transmission, decoration, still only

In addition, the net cloth is made of money, and the black layer is formed on the mesh cloth, thereby changing the color of the silk, and after the exposure is performed, the complete pattern rim can be presented on the photoresist layer, after development, A precise ink-permeable area is obtained, which produces a complete and vivid pattern. The manufacturing method of the screen screen provided by the invention comprises the following steps: (1) providing - weaving into a woven fabric by a plurality of warp yarns and weft yarns, and combining the mesh fabric into a frame body to form a screen; (2) Each warp and weft interlaced portion of the mesh is fixed together to form a net knot; (3) forming a blackening layer on the surface of the mesh; (4) forming a photoresist on the surface of the blackening layer; 5) exposing the screen; (6) developing the screen to form a 201235223 ink-permeable area of a predetermined pattern on the mesh. The invention provides a screen printing method capable of producing a precise printing pattern, in particular, in the method of mesh netting and net blackening, which can avoid deformation of the mesh and ensure the integrity of the printed pattern. And dimensional accuracy. 201235223 [Embodiment] Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings and the reference numerals, which can be implemented by those skilled in the art after the study. Please refer to the first figure for a flow chart of the manufacturing method of the printing screen for the present invention. The method comprises the following steps: (1) providing a mesh cloth woven from a plurality of warp yarns and weft yarns, and combining the mesh cloth into a frame body to form a screen; φ (2) each warp yarn and weft yarn of the mesh cloth The staggered portion is fixed at a position to form a mesh knot; (3) forming a blackening layer on the surface of the mesh; (4) forming a photoresist on the surface of the blackening layer; (5) facing the mesh The plate is exposed; (6) developing the screen to form a predetermined pattern of ink-permeable regions on the mesh. Φ π 配 & Referring to the first figure, the warp yarn 11 and the weft yarn 12 described in the step (1) are the ridges of the plurality of wires which are staggered in the transverse direction and the longitudinal direction, and are woven to form a metal mesh cloth 1 which is preferably a stainless steel wire. , has a lower elastic deformation force, can ensure the subsequent (four) _ sister height of the scale capture density. _ cloth around the adhesive inside! 2' The mesh 1 is bonded to the inner surface of the frame 3; the selected frame 3 may be a metal or non-metal frame such as iron, an inscription or a wooden frame; the finished screen is as shown in the third figure. Please refer to the fourth figure. In step (2), the warp yarns u and the weft yarns 12 are fixed together by an electric binding method to form a net knot 13. 201235223 Mainly to avoid the offset of the warp u or weft ι2, V to the shed when the printing machine scraper is walking, can not do accurate overlapping printing. Lai's electric town can consult & use the nickel alloy with tensile strength. In the step (3), the blackening layer 4 is formed by using a black layer on the screen to make the black layer fully adhere to the surface of each warp yarn n and weft yarn D. Molding; the function of forming the blackening layer 4 on the mesh 1 is to prevent the mesh 1 from being inexposed in the exposure due to the luster of the gold. After the blackening operation is completed, a degreasing agent may be provided to clean and degrease the mesh cloth 1 to remove grease, impurities or dust on the mesh cloth, so that when the photoresist is coated, the photoresist can be completely attached to the coating. There is a surface of the mesh 1 of the blackening layer 4. The light_成财式 is formed by immersing the surface of the blackening layer 4 and drying it. The emulsion can be oily or water-based. If you want to use oily ink to print the screen, it must be oil-based emulsion plate making, silk coating. After the completion, you must be on the mesh! Dry. Then, the pattern master to be printed is placed on the dried photoresist, and exposed by ultraviolet light, the photoresist in the non-exposed area can be dissolved by the developer, and the undissolved portion forms a hardened dielectric layer 5 (such as The ink-permeable region 6 refers to a mesh mesh that is not covered by the dielectric layer 5, and allows ink to flow over the printed matter. The fifth figure shows a cross-sectional view of the black layer 4 and the dielectric layer 5 formed on the mesh 1 in sequence, and the sixth layer represents the dielectric layer 5 in the mesh! The stereo state on the top. Because the mesh cloth 1 has been subjected to blackening work in advance, the original warp yarn and the weft color of the weft yarn are used, so that the exposure will not cause refraction. 201235223 will be more difficult to fully expose the mother #_L, after (10)f彡, in the ink The tangential part of the area is divided into four parts. The phenomenon of incomplete development of the corner shape is not complete, so that the shame can be obtained _ and the size is correct. The above description is only for explaining the preferred implementation of the present invention. For example, it is not the case that the invention is subject to any form limitation, so that all are in the same
