ABSTRACT:
The invention relates to a method for producing a calendered paper web. According to the method, a paper web is formed from a fibrous raw material in a paper machine, and the paper web is calendered. According to the invention, a fibrous raw material is used which is at least partly made up of a chemimechanical pulp of a species of thePopulusfamily, and the calendering is performed by online soft-calendering. By means of the invention, the gloss and smoothness of papers can be improved without decreasing their bulk.
