An object of the present invention is to provide a process for preparing a high-quality coated paper with high runnability while preventing damage to the elastic roll surface of the soft calender encountered during high-speed operation. The present invention provides a process for preparing a coated paper, comprising the steps of: making a base paper; applying a coating solution containing a pigment and an adhesive on the base paper to form one or more pigment coating layers; and surface-treating the pigment coating layers by a soft calender, said papermaking and coating steps being performed at an operating speed of 1300 m/min; wherein said surface-treating step comprises treating the outermost one of the pigment coating layers using a soft calender comprising a metallic roll and an elastic roll with at least two or more nips and wherein the elastic roll has a Shore D hardness of 90 - 96 and the metallic roll surface temperature at the first nip is less than 130 °C.
