The mesh number can generally explain the density between the wires of the screen. The higher the mesh number, the denser the mesh and the smaller the mesh. Conversely, the lower the mesh, the sparser the mesh, and the larger the mesh, such as 150 mesh/inch, that is, there are 150 mesh wires in 1 inch. The smaller the mesh, the worse the ink permeability, and the larger the mesh, the better the ink permeability. When selecting the screen, you can choose screens with different meshes according to the printing accuracy requirements.

The opening actually represents the width of the mesh, which is represented by the square root of the mesh area surrounded by the longitude and latitude of the mesh (usually in microns, 1 micron = 1/1000 mm). Therefore, the longer the length of one side of the mesh, the larger the opening.
