Abstract (en)
[origin: WO2020078606A1] The invention relates to a method for printing on a surface of a nonabsorbent substrate (01) with an ink to be applied by an inkjet printing device (02), wherein: an ink containing water as a solvent is used to print on the substrate (01), an ink having a water proportion of at least 70% being used; the substrate (01) to be printed on is supported by a workpiece support (04) and is moved relative to the inkjet printing device (02); during this relative movement, ink is applied by the inkjet printing device (02) to the surface of the substrate (01) to be printed on; the ink applied to the surface of the substrate (01) is heated to a temperature that lies above the temperature of the air surrounding the substrate (01) and below the boiling temperature of the of the solvent contained in the ink; a vapor layer consisting of the solvent contained in the ink is formed above a liquid phase of the ink; the vapor layer formed above the liquid phase of the ink is transported away by means of an air flow discharged from at least one blowing nozzle unit (06; 07); the air output by the blowing nozzle unit (06; 07) in question is heated and/or dehumidified beforehand. The invention further relates to a digital printing machine for carrying out said method.
