Abstract
Method for conditioning paper, which comprises a first step of cooling and one of applying a liquid to the paper. In the cooling step, the temperature of the paper is reduced, e.g. below ambient temperature or below the dew point of a liquid-saturated gas mass applied in the liquid-application step. The gas may be ambient air and the liquid water. Control means monitor the amount of liquid applied to the paper by means of measuring the relative humidity of the air, the absolute humidity of the paper, the temperature of the device where the liquid is applied and the temperature of the paper. The invention also comprises a device for applying the method and it may be applied to paper emerging from a printer, e.g. a digital printer.
