A method for setting optimal pre-inking before the start of printing in an inking unit in a press having at least one printing unit. The settings for the pre-inking are determined by an electronic control device belonging to the press. At least one standard characteristic curve for controlling the pre-inking before the start of printing is stored in the electronic control device of the press for at least one combination of parameters of a print job. On the basis of this stored standard characteristic curve, a current characteristic curve is calculated as a function of the job data of a current print job. Finally, the the pre-inking before the start of printing the current print job is controlled by using this current characteristic curve.

Method of setting optimized pre-inking prior to the start of printing the current print job

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.
