Several key factors about select screen printing mesh (2)
Today continues to introduce several key factors in choosing a screen printing mesh.
Nylon mesh is suitable for making screens for printing complex surfaces or containers. Nylon is more extensible than polyester and can accommodate rough, uneven or rounded surfaces. However, its properties make it unsuitable for most applications requiring dimensional stability and low elongation.
Stainless steel wire has the highest strength to meet the requirements of the wire diameter, so it is suitable for fine printing. Fine printing requires precise coverage of the ink and good dimensional stability for better registration.
Since the steel wire is strong, it is possible to use a very thin steel wire. The fine mesh reduces the incidence of mesh interference and a reduction in the incidence of the serrated and moiré, and improves the transfer of ink. In addition, in order to accurately control the screen, it is possible to twilight, which in the process of calendering, presses the nodules of the mesh together, so that the screen has better dimensional stability. This screen is used for electronic precision printing. Stainless steel wire mesh is also made in 3D size for printing particularly narrow lines. This screen achieves both a thick ink layer and sharp edge definition because it extends in a straight line in one direction and reaches the highest point on the opposite screen to achieve greater depth.
Regardless of the material, advances in wire composition and construction have increased the printing capabilities of different applications.
The screen printing screen of the woven structure has two kinds of weaving methods: plain weave and twill weave. Most are 1:1 plain weave. The mesh range is 15 mesh (or less) to 508 mesh (or more i. The thickest polyester mesh is usually used to print textiles, using shiny inks or other large particle inks, or using adhesives or glues). Industrial application. The mesh diameter exceeds 400mm, and the thickness of the mesh is about 900Mng. The mesh size of many polyester meshes in the range of (35~63) m claws is suitable for a wide range of applications, including decals. Printing, POP graphic printing, industrial printing and OEM printing, etc. (433) Mm, suitable for very fine screens. These screens are used for extremely thin lines and high-line four-color printing. Again, the minimum dots should be covered. Three meshes are used to avoid dot loss. Stainless steel wire can be as thin as 11Mm and woven at 840 lines/inch, which is very surprising, and it will continue to be developed to meet more demanding printing needs.
