Problems solved by technology

If you can achieve 20-40 micron line printing, while ensuring straight lines and certain height requirements, you can reduce the cost by about 20%, but because the 20-40 micron line is too thin, the screen will block part of the graphic area during printing. phenomenon, then the printed lines will appear incomplete or uneven

Abstract

The invention discloses a metal mesh printing plate and a preparation method thereof. The metal mesh printing plate comprises a metal mesh and a polyester mesh, wherein a metal layer is arranged on a non-pattern area in the metal mesh; a pattern area is positioned in the non-pattern area; in the weft direction, warps are removed by intercepting treatment at a position corresponding to the pattern area, and / or, in the warp direction, wefts are removed by the cutting treatment at a position corresponding to the pattern area; the quantity of the wefts / warps subjected to the cutting treatment is more than or equal to 1. According to the metal mesh printing plate, the warps / wefts are removed by cutting at the position corresponding to the pattern area; the cut wraps / wefts at the position corresponding to the non-pattern area remain high strength due to that the wraps / wefts are electroplated with metal layers; in addition, printing areas covered by the wefts / wraps can be reduced, and the ink can be leaked uniformly and richly, so that printed patterns are clear and accurate, and as a result, the printing quality can be improved.

Description

technical field [0001] The invention relates to the field of metal mesh printing, in particular to a metal mesh printing plate and a preparation method thereof. Background technique [0002] With the development of metal mesh printing technology, the width of metal mesh printing lines is getting thinner and thinner, and the requirements for printing lines such as good straightness, small widening, and small ups and downs are becoming more and more stringent. [0003] When making traditional metal mesh screens, the mesh and printing lines must have a certain angle (22.5 degrees, 30 degrees, 45 degrees, 60 degrees, etc.), resulting in a certain proportion of net knots in the printing line area. The leak holes that need ink penetration are unevenly distributed. [0004] To solve the above problems, the lines are parallel to the mesh plate making. If you can achieve 20-40 micron line printing, while ensuring straight lines and certain height requirements, you can reduce the co...
