Abstract
A process for manufacturing a coated paper for use in printing is characterized in that the coated paper for printing is produced by coating a color consisting mainly of pigment and a water-soluble binder made of starch or starch derivatives to the surface of a base paper, then drying and finishing it. Steam or an aqueous penetrant solution having a penetrating force of less than 50 seconds is sprayed or applied over the dry coated layer surface of the coated paper, prior to it being finished with a calender, for redistributing the water-soluble binder in the coated layer in order to correct its uneven distribution, which is the cause of printing mottle during the offset printing operation.
