The finest width of the fine lines of the screen reproduction means that in the screen printing, what is the width of the screen that can be used to reproduce the thinnest line?
This is usually directly related to the mesh and mesh width. The following formula can be used as a basis for selecting the screen calculation when selecting the network. The formula for the thinnest line width value:
K=2S 十 R where: K represents the width of the thinnest line, S represents the wire diameter value of the wire, and R represents the width of the mesh.
Calculation example: If a 200 mesh/inch nylon mesh is used, what is the minimum width of the reproduction line?
Check the NM200-inch screen with a wire diameter (S) of 0.05 mm and a mesh width (R) of 0.077 mm. Substituting the above formula, K=2×50 十77=177 =0.177 mm NM200 mesh/inch screen reproduction The thinnest width of the line is 0.177 mm.
