Ink manufactures and screen printer on earth has their own ideas as to what mesh should be used.We will give you our idea of mesh count your usage.
Light color material needs less ink layer to cover,so use higher mesh counts.
Darker color materials need a thicker ink layer,so use lower mesh counts.
Remember,thicker ink layers require more cure time,the reverse is also true.
Printers using a manual press should stay between 38 and 125,maybe 158 mesh,Any mesh higher than say 196 requires a lot of strength to push the ink through.Now automatic press owners,can use the full range of mesh counts.
