Abstract:
1. A method to set a dot size of toner images generated with aid of an electrographic printing or copying system, comprising the steps of: generating at least one latent raster image that is not to be inked with toner particles in at least one region, said at least one latent raster image to be inked in other regions with toner particles to form a first toner image; generating at least one additional latent raster image that is to be inked with toner particles over its entire surface, said additional latent raster image being inked with toner particles to form an additional toner image; determining a first toner particle quantity that is used to ink the at least one toner image and a second toner particle quantity used to ink the at least one additional toner image with aid of a sensor unit; determining a ratio of the first toner particle quantity and the second toner particle quantity; using the determined ratio as a measure representing a real value for an areal coverage of the first toner image and comparing the real value with a desired value; and setting an electrical field to transfer toner particles to said regions of the at least one latent raster image that are to be inked depending on a result of the comparison.
