A method for drying a printing ink on a printing material in a printing machine and printing machine

There will be described a method for drying a printing ink (114) on a printing material (14) in a printing machine (30) and a print engine (30). The substrate (14) is printed (18) of the path (16) with at least one printing ink (114) moves along a path (16) through the printing press (30) and at a first position. At a second position (124) of the path (16) is applied in a Konditionierwerk on the substrate (14) a treating agent (118), which causes an acceleration of the drying of the ink (114) on the substrate (14) and in particular an infrared absorber includes having an absorption wavelength, the resonant at substantially the wavelength of the light (12) of the radiant energy source (10). Temporally downstream of a third position (116) of the path (16), the printing substrate (14) by the action of radiant energy of a drying device, particularly a narrow-band radiant energy source (10), are dried in at least.
