Abstract
Methods for producing cast-coated papers showing a reduced level of curling and reduced curling or wavy deformation caused by moisture absorption or other reasons as well as showing a high surface quality in the cast-coated surface. The steps for producing cast-coated papers include applying a coating color based on a pigment and an adhesive on one side of a base paper, and pressing/drying the coated layer in the wet state against a casting drum mirror surface, where moisture is added to the coated paper by passing it through conditioned air at a high temperature and a high humidity (for 20 seconds or more) after pressing/drying the coated layer against a casting drum.
