Masking plate with composite structure

Abstract

The invention discloses a masking plate with a composite structure. The masking plate is composed of a plane silk screen with a composite structure and one or multiple photosensitive polymer layers coated or pressed on the plane silk screen. The plane silk screen with a composite structure is composed of a non-graph area and a graph area. The graph area is composed of two and more graph sections with different mesh numbers in the same direction. The graph area is formed through regular arrangement of gridding arrays with different gridding shape structures. The plane silk screen with a composite structure is produced through electroforming integrated molding and has no woven longitude-latitude nodes. The photosensitive polymers on the masking plate are arranged to be in a hollow state in a designated area, and forms a printing zone with meshes in the area. The other area in a non-hollow state forms a masking zone combined with the plane silk screen. The masking plate with a composite structure can meet special printing requirements for local areas during the printing process of the printing industry. Because the plane silk screen with a composite structure is formed through electroforming integrated molding, the masking plate has a smooth surface and no woven nodes, solves the problems of unsmooth plate surfaces of traditional masking plates with longitude-latitude nodes, uneven material loading during printing and easy damage during wiping and cleaning, avoids complex weaving technologies of traditional masking plates, and raises the efficiency.

Description

[0001] technical field [0002] The invention relates to the field of electronic printing, in particular to an electronic printing tool. [0003] Background technique [0004] At present, the development of the printing industry (including the printing of flexible paste such as ink and silver paste) has higher and higher requirements for printing quality. In the printing process, the quality of the printing medium (ie, the printing mask) is directly related to the final product. D. The structure of the traditional printing mask is formed by coating a layer of photosensitive polymer on the surface of the traditional screen, wherein the traditional screen constituting the mask is a woven polyester mesh or metal mesh, such as figure 1 As shown, because the wires that make up the structure of the woven wire mesh are independent of each other, a small gap is formed at the intersection of each other (such as figure 2 The longitude and latitude nodes shown in B2 in (b) (such as...

Problems solved by technology

The structure of the traditional printing mask is formed by coating a layer of photosensitive polymer on the surface of the traditional screen, wherein the traditional screen constituting the mask is a woven polyester mesh or metal mesh, such as figure 1 As shown, because the wires that make up the structure of the woven wire mesh are independent of each other, a small gap is formed at the intersection of each other (such as figure 2 The longitude and latitude nodes shown in B2 in (b) (such as figure 2 (a) As shown in B1), on the one hand, it forms the bumps of the overall surface of the mask plate, resulting in uneven surface, uneven material blanking during printing, and uneven height and size of the final product, such as thin grid lines of solar panels At the same time, due to the weaving process used, it is difficult to completely guarantee the straightness of the silk thread. When it is prepared into a mask plate, the shape of the cross-sectional edge of the final product formed is irregular and easily wavy; on the other hand, Due to the weaving process, the process is complicated, the operation is not easy, and the efficiency is low; third, due to the weaving process, it is difficult to realize the change of the local structure of the flat screen, that is, the mesh number of the entire flat screen mesh is consistent, and it is difficult Changes, when there are special requirements for the final product locally and the mesh number of the flat screen at the corresponding position is required to change, the traditional weaving process is difficult to achieve
