Abstract
A method for alternately operating an inkjet printing machine applying a plurality of inks to a printing material in accordance with a print image, includes conveying the printing material at a conveying speed. A switch is made between the following two modes, a 1mode of printing an n-color first print job at a first conveying speed and at a print resolution using n inks, i.e. using black ink and n−1 different chromatic inks; and a 2mode of printing a reduced-color second print job at a second conveying speed greater than the first conveying speed and at the same print resolution using the n inks. The printing speed and thus the number of prints produced per unit of time in a machine can therefore advantageously be increased.
