METHOD AND APPARATUS FOR COMPENSATING PRINTING ELEMENT SHOOTING POSITION DEVIATION

The present invention relates to a method of controlling an inkjet printing device comprising a print head. In the method of controlling an inkjet printing device of the present invention an inkjet printing device comprises a print head, wherein the print head comprises an array of printing elements arranged to eject a number of droplets of a liquid onto a recording medium resulting in an array of dots on the recording medium. Depending upon the magnitude of the shooting position deviation of the printing elements of the array, in order to avoid the appearance of artefacts in the printed image, the present invention creates a second raster image derived from a first raster image created from the image to be printed, in which a redistribution of the pixel coverage values is performed based on said magnitude of the shooting position deviation of the printing elements of the array.
