Selecting Proper Mesh Count in Screen Printing

The size of the mesh has a lot to do with how thick the ink you are using is How detailed your image is also a consideration in the mesh count selection If you have a design with extremely high detail a lower mesh screen won t hold the fine lines or dots in the image and they will simply not show up causing a lack of detail in the finished product...
