Abstract
Precise control of the wetting of an edge guide by a coating fluid (i.e., the wetting profile) can be achieved by providing a wetting line below which the coating fluid will wet the surface of the edge guide. Preferably, the height of the wetting line corresponds to a predetermined depth profile of a coating fluid flowing down a coater face. Optionally, a non-wetting surface can be provided above the wetting line, and the non-wetting surface can optionally have a low energy coating provided thereon.
