Abstract: Methods of high speed coating a pigment-containing liquid coating material onto a substrate so as to avoid visible pigment separation in the coating material in its as coated state. In the method, a pigment-containing liquid coating material is applied to a substrate, while the substrate is moving at a high line speed of at least about 15.24 m/min., to form a coated layer. The coating material is applied to the substrate along a substantially straight, dynamic wetting line where the coating material first contacts the moving substrate. The coating material is of the type that will exhibit visible pigment separation on its interface surface when the coating material is coated onto the fast moving substrate, without the use of a substantially straight wetting line. The wetting line is substantially straight when a significant amount of visible pigment separation does not occur at the chosen high line speed.
