A method and assemby is disclosed for manufacturing a two-layer coated paper web, the method comprising the steps of applying a coating furnish layer to at least one surface of said paper web, drying the applied coating furnish layer to a point allowing a next coating layer to be applied thereon. Onto the first coating layer is applied a second coating layer that is dried. The application of successive coating layers is continued until the desired coat thickness is attained. The coating layers are applied using a metering film transfer method operating without leveling of the applied coating layer by doctoring, whereby in at least one of said coating layers is used a furnish having a solids content of not less than 62%.
