Screen printing meshs are inseparable from the production of screen printing. Screen printing screen printing is inseparable from screen printing mesh. How to choose the right printing mesh?
When screen printing, the quality of the mesh is very good and bad, which affects the printing effect after us. The choice of mesh is very important.
Screen printing mesh structure and mesh
The wire diameter of the wire is the two-dimensional and three-dimensional appearance of the wire, that is, the basic elements of its geometry are the mesh number of the wire and the diameter of the wire.
For example: 120-34 indicates 120 meshes per cm, and the diameter of each mesh is 34um.
The mesh number of the wire mesh refers to how many wires are in each centimeter.
The diameter of the mesh refers to the nominal value of the mesh diameter that has not been sewn.
The screen opening is determined.
The smallest size of the particles in the screen printing ink (the average particle size of the ink in the printing must be greater than 1/3 of the mesh).
The level of detail of the lines and dots printing (very small holes are too leaky, no detailed lines)
The peeling performance of the ink (such as the small particles of the ink cause the netting to impinge on the penetration of the ink at the next printing)
The thickness of the printed ink layer (the opening is very large, the amount of ink is also difficult, and the thinner ink layer is not obtained)
The opening of the screen printing mesh is a mesh that is smaller than the diameter of the mesh than the mesh. Screens larger than the diameter of the wire can copy lower and lower resolutions.
