Abstract
A method prints and dries a substrate where ink containing water and pigment is printed onto the substrate in an inkjet printing process. The substrate has an initial moisture content and absorbs at least water of the ink, causing the moisture content of the substrate to rise. Radiation selectively acting on the water molecules is applied in a first drying step and then radiation selectively acting on the pigment is applied in a second drying step in such a way that after completion of the two drying steps, the water of the applied ink has essentially completely evaporated and the substrate has essentially reattained its initial moisture content. In this manner optimum drying of substrates to which ink has been applied occurs.
