System and methods for applying a liquid coating to a substrate are disclosed herein. One exemplary method includes a flow control routine in which the velocity of an applicator, or other parameter affecting the amount of material applied to the substrate, is iteratively adjusted. The amount of the adjustment performed in each iteration is tracked. When the sum of the adjustments by the flow control routine exceeds a predetermined threshold, a fan width control routine is initiated in which the fan width of the stream of material applied by the applicator is adjusted.
