CA 2198991

The present invention relates to a method for coating a paper or paperboard web by at least two coat layers. The goal is to achieve a two-layer coating method capable of providing a smooth coat with high opacifying power. The invention is based on initially applying onto the web to be coated a first coat layer, whose surface is smoothed by means of a smoothing element. After smoothing, this first coat layer is partially or entirely dried, and a second coat layer is applied to the first coat layer using a transfer roll coater.
