A method for drying a printing ink () on a printing substrate () in a printing press (), one printing ink () having one color pigment being used to print on the printing substrate () at one position () of a path () along which the printing substrate is conveyed through the printing press (), and, at a chronologically later point in time, at one further position () of the path (), the printing substrate () being illuminated with light () from a laser light source () having a wavelength of between 350 nm and 700 nm, the wavelength being resonant to an absorption wavelength of the color pigment of the printing ink (). A print unit () for implementing the method is described which has a laser light source () which emits light () of a wavelength of between 350 nm and 700 nm.
