Abstract
In a method or system to set a dot size of toner images, at least one latent raster image is generated that is not to be inked with toner particles in at least one region to form a first toner image. At least one additional latent raster image is generated that is to be inked with toner particles over its entire surface, the additional latent raster image being inked with toner particles to form an additional toner image. With a sensor unit a first toner particle quantity is determined which is used to ink at least one toner image and a second toner particle quantity is determined which is used to ink the at least one additional toner image. A ratio of the first toner particle quantity and the second toner particle quantity is determined. The determined ratio is used as a measure representing a real value for an areal coverage of the first toner image and the real value is compared with a desired value. An electrical field is set, depending on a result of the comparison, to transfer toner particles to regions of the at least one latent raster image that are to be inked.
