T-Mesh versus S-Mesh
In high-end screen printing, we now use more often the S-Mesh instead the T-Mesh.
As it have a better coverage and most printer use it for the under base.
But not only for the under base, as specially for water base ink, it shears more easy with less pressure.
The result is not only better opacity, but a softer hand too.
Why Screen Printer use a S-Mesh:
1) Better Opacity
2) Less Ink Usage
3) Less Emulsion Consumption
4) Soft hand
5) Less Squeegee Pressure
Be aware, as the S-Mesh is much finer then the T-Mesh, it is more delicate to work with.
