The calculation of the finest width of fine lines in screen reproduction

In screen printing, the precision of reproduction of a replica is closely related to the screen. The number of screen meshes has an important influence on the reproduction of the fine lines of a manuscript. Therefore, when selecting a screen, careful selection must be made. The number of screen meshes must be selected. Corresponding to the printing of fine lines, the selected screen size has the ability to reproduce the fine lines of the original so as to ensure the printing effect.

Screen printing fine lines generally refers to line widths between 0.1-0.2 mm. The finest width of the silkscreen reproduction fine line refers to the value of the width of the screen that can be reproduced by the selected screen in screen printing. This is usually directly related to the width of the mesh and the mesh. When selecting a network, the following formula can be used as a basis for selecting a screen calculation.

The formula for calculating the thinnest line width:

K=2S ten R

K represents the width of the thinnest line,

S represents the screen wire width value,

R indicates the width of the mesh.

Calculation example:

If you use 200 mesh/inch nylon mesh, what is the finest width of the reproduction line?

Check the NM 200-inch wire mesh 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 and 77=177=0.177 mm

The finest width of the NM200 mesh/inch screen reproduction line is 0.177 mm.
