How to Choose the Right Screen Mesh Size ScreenPrinting

Mesh size is measured by how many threads of mesh there are crossing per square inch. For instance, a 110 mesh screen has 110 threads crossing per square inch. The higher the mesh count, the finer the threads and holes are in the screen. The size of the mesh has a lot to do with how detailed your image is and how thick the ink you are using is.
