  • Patent number: 10836158
    Abstract: A method for compensating for position-dependent density fluctuations in an inkjet printing machine includes the steps of assigning, by using a look-up table, specific halftone patterns to specific gray values of a color separation to be screened of an image in the course of the calibration of a raster image processor of the inkjet printing machine, using the halftone patterns in the image screening process by using the computer and printing the halftone image on the inkjet printing machine. The look-up table contains the position of every printing nozzle of the print heads in the inkjet printing machine as an additional variable and the computer enters a complete set of gray values with associated adapted halftone patterns into the look-up table for every position of a printing nozzle.
