How to choose a wire mesh?
1.Nylon mesh: nylon mesh has high strength, high wear resistance, high alkali resistance, poor acid resistance, good ink permeability, small wire diameter, good elasticity and vivid imprint; 2. polyester mesh: polyester Good stability, high strength, corrosion resistance, performance better than nylon mesh, high tensile tension, suitable for high-precision printing; 3. stainless steel wire mesh: stainless steel wire mesh with high strength, good stability, small wire diameter, mesh High, good resistance, long life, poor elasticity, easy to break by impact, suitable for precision printing, not suitable for curved surface printing; 4. nickel-plated polyester mesh: nickel-plated polyester mesh integrated with the advantages of polyester mesh and stainless steel wire mesh Wide applicability, moderate price and poor corrosion resistance. The screen has plain weave, twill weave, semi-twisted weave, and full weave. When the white screen is exposed, it is easy to cause diffuse reflection, and the golden, red and amber colors absorb ultraviolet rays, which can prevent halo. The number of mesh meshes is 30 mesh/cm, 40 mesh/cm, 60 mesh/cm, 80 mesh/cm, 120 mesh/cm, 140 mesh/cm and 160 mesh/cm, etc., in general, mesh The number is large, and the mesh is straight. Filament dense mesh, high resolution; coarse coarse mesh resolution is low. When printing curved surfaces, use a large elastic mesh, such as nylon mesh; when printing large substrates, use a mesh with a large mesh area; when printing smooth surfaces, use a high-elastic, high-tension mesh; When using low-mesh screens; when printing high-precision prints, use low-elongation, high-tension screens; when printing signboards, textiles, and knitwear, use 28 mesh/cm to 78 mesh/cm screen; For paper, metal, glass, leather, and plastic, use a mesh of 40 mesh/cm to 140 mesh/cm.
Screen printing mesh features: 1 wide adaptability: screen printing format can be large or small 2 ink color thick: in all printing processes, screen printing ink layer is the thickest, high saturation, spot color printing effect is better 3 low cost: Screen printing plate making is easy, printing process is simple 4 print quality is fixed; 5 production efficiency is low: screen printing speed is slow, not suitable for online production 6 image accuracy is low: screen printing resolution is not high, conventional screen line number 24 lines / cm ~ 32 lines / cm
