The total thickness of the emulsion will determine the thickness of the ink deposit on the screen. We usually coat our 110 screens twice on the shirt side, once on the ink side in order to print a opaque white ink on dark shirts with a print/flash/print. I would suggest to at least coat each side of the screen once to totally encapsulate the mesh in emulsion. You can control the amount of ink going through the screen with a finer mesh if needed or a coarser mesh if you need more ink. Mesh count in addition to emulsion thickness will determine how much ink gets onto the screen.
