The invention relates to a method and an arrangement in the manufacture of coated printing paper when coating the paper web at least on one side. For drying the paper after the coating station, a dryer is used by means of which the web is dried with hot air or superheated steam or infrared radiation, or a combination of these is used. The said dryer is placed immediately after the coating station. The drying of the paper is continued in the said dryer at least until the coating in the dryer area reaches its solidification point.
