Abstract
A method for modifying a digital image having an array of raster lines, each raster line having an array of image pixels, to produce a modified digital image suitable for printing on an inkjet printer containing at least one printhead having nozzles, such that unwanted optical density variations in the print are reduced, includes determining an optical density parameter for each nozzle in the printhead; determining a line correction factor for a given raster line in response to the optical density parameter for each nozzle in the printhead and the raster line number; and modifying each pixel in the given raster line in response to the line correction factor to produce the modified digital image.
