Abstract

A system for applying a fluid coating onto a substrate includes forming a fluid wetting line by introducing a stream of fluid onto a first side of the substrate along a laterally disposed fluid-substrate contact area. An electrical force is created on the fluid from an electrical field (originating from electrical charges which are on the second side of the substrate) that is substantially at and downstream of the fluid wetting line. The electrical field can be generated by charges that have been transferred to the second side of the substrate from a remote charge generator.
