A method for compensating for Streifigkeiten in a printed halftone printing print image in a digital printer

In the method the Langsstreifigkeiten be compensated in a printed image in the raster printing. The digital printer includes a series of printing elements, each printing element prints in the printing direction printing dots in a print dot row on a recording medium. Due to the pressure elements a test printing image with a predetermined target tone value will be printed. The onto the recording medium (3) printed test print image is scanned by a scanner, and from the scanned test print image is calculated for each pressure point number the actual value of the tone value. This actual value is compared with the setpoint. In case of deviation of the actual value of the tone value from its desired value, the print data per print element can be corrected in dependence on the difference over arranged in a correction table correction values ​​(12), that for each printing element which printed by the printing element in the print dot row printing dots the target tone value for this print dot row result.
