A method of coating moveable supports at high speeds comprises moving the support along a path through a coating zone, forming two or more layers of coating liquids including an actual top coat layer to form a liquid composition (with a slide hopper coating a plurality of outlets for coating liquids) and applying a starting top most layer of coating liquid, which layer has a lower viscosity than that of the actual top coat layer, to the liquid coating composition either through the first outlet of the hopper or through an x-hopper located between the first outlet and coating zone, applying the coating composition and starting top most layer, and terminating the application of the starting top most layer when the coating operation is at steady state. Apparatus for carrying out this method is also described.
A method for applying multiple layers of coating liquids to a moving support comprising:
