(2) \u003cstrong\u003ePick-up\u003c\/strong\u003e: As it emerges vertically, a liquid film adheres to both sides of the substrate. (3) \u003cstrong\u003eMetering (The Landau-Levich Regime)\u003c\/strong\u003e: The final thickness is determined primarily by the withdrawal speed and the viscosity of the fluid.
