Abstract
In a method for free spraying of the nozzles of an inkjet print head, in particular in a franking and/or addressing machine, in which the print media are directed past a stationary inkjet print head, in addition to printing an information-conveying print image, non-information-conveying a print image, serving exclusively for the free spraying, is applied on the print medium in a form that is for the print image evaluation, while retaining the same print position for the inkjet print head. Both print images are combined into a resulting print image. It is thus ensured that each nozzle is activated at least once during the print image generation. By the retention of the print position, time is saved and the letter travel is optimized.
