A method of making screen based on metal plate engraving

Abstract

The invention discloses a manufacturing method of a screen printing plate based on metal plate carving. The method comprises the following steps of 1, engraving a metal plate; 2, positioning; 3, prefabricating a photosensitive film; 4, adhering the photosensitive film; 5, cutting and tearing films; and 6, conducting exposure. According to the manufacturing method of the screen printing plate basedon metal plate carving, a traditional method of conducting photosensitive manufacturing of print grid line areas after a warp and a weft is interwoven is replaced, print grid line hollows for printing are directly engraved on a metal plate, and then other parts of print grid line hollows are carved with meshes to form a gauze. In this way, the print grid line hollows for printing and the print grid line hollows can be partitioned, so that the screen printing plate without the gauze can be truly realized, and therefore the printability is strong, and the structural strength of the screen printing plate is more reliable.

Description

technical field [0001] The invention relates to a screen making method based on metal plate engraving. Background technique [0002] Screen printing technology is an ancient civilization and a long-lasting industry, which is widely used in people's production and life. Especially in recent years, with the high development of the electronics industry, the screen printing process has been well applied, and a vibrant scene has appeared. At the same time, higher and higher requirements have been put forward for the accuracy of the screen. The basic structure is the screen frame, the mesh, and the printing grid line area on the screen yarn; at present, the mesh yarn is generally interwoven through metal warp threads and metal weft threads, and the printing grid area is on the mesh yarn, which is bound to be exhibited at the meeting. As a result, there is an overlap between the printed grid area and the mesh, which reduces the printability; in addition, the metal warp and metal w...

Especially in recent years, with the high development of the electronics industry, the screen printing process has been well applied, and a vibrant scene has appeared. At the same time, higher and higher requirements have been put forward for the accuracy of the screen. The basic structure is the screen frame, the mesh, and the printing grid line area on the screen yarn; at present, the mesh yarn is generally interwoven through metal warp threads and metal weft threads, and the printing grid area is on the mesh yarn, which is bound to be exhibited at the meeting. As a result, there is an overlap between the printed grid area and the mesh, which reduces the printability; in addition, the metal warp and metal weft will be bent and deformed, so that the metal warp and metal weft touch the grid area, resulting in deformation of the printed grid area, which in turn leads to post-processing. Printing failure; In addition, the way of exposure on the mesh is generally to paint the photosensitive glue on the mesh, then heat and cure the photosensitive glue on the mesh, and then expose the photosensitive glue on the mesh through the exposure of the film. After exposure and washing, the screen printing pattern is obtained, and the photosensitive adhesive in this way is directly painted on the mesh, the stability is not good, the photosensitive adhesive is unevenly painted and the thickness cannot be controlled, which affects the printing performance of the printed pattern
