A method for drying a printing ink () on a printing substrate () in a printing press (), and a printing press (). The printing substrate () is moved along a path () through the printing press () and printed on by at least one printing ink () at a first position () of the path (). At a second position () of the path (), in a conditioning apparatus, a treatment agent () is applied to the printing substrate () to accelerate the drying of the printing ink () on the printing substrate () and includes, in particular, an infrared absorber which has an absorption wavelength that is essentially resonant to the wavelength of the light () of the radiant energy source (). The printing substrate () may be dried by the action of radiant energy at a chronologically later point in time, at at least one third position () of the path (), by a drying device, in particular by a narrow-band radiant energy source ().

A method of adjusting a quantity of ink supplied to a printing material by a printing machine includes adjusting the quantity of ink as a function of the printing speed and, upon the occurrence of a change in the printing speed, making a change in the quantity of ink as a function of area coverage to be printed; and an adjusting device for performing the method.

The present invention relates to a method for controlling the ink feed in a printing press which processes printing substrates ( ) and features at least one inking unit and one computer and to a device for carrying out the method. The present invention is characterized in that the computer knows at least the physical properties of printing ink and/or printing substrates ( ) as data, that the stored data is read into an ink control model which is stored in the computer, and that the optimum settings with regard to the ink feed are made on the basis of this ink control model before the start of printing or during the printing process.
