Abstract:
1. A method for drying a printing ink on a printing substrate in a printing press comprising the steps of: using at least one printing ink to print on the printing substrate at a first position of a path, the printing substrate being moved along the path through the printing press; and applying a treatment agent at a second position of the path on the printing substrate to accelerate drying of the printing ink on the printing substrate; and wherein the printing substrate is dried by the action of radiant energy at a chronologically later point in time from the using and applying steps at least one third position of the path; and wherein at least the third position of the path, the printing substrate is illuminated with light from a narrow-band radiant energy source, and wherein the treatment agent includes an infrared absorber with an absorption wavelength resonant to the wavelength of the light.
