A method of producing a printing plate on a cylindrical printing-plate carrier in a rotary printing press uses a digital imagesetting unit and a raster image processor. The method includes subdividing the printing-plate carrier by computation in terms of its width and axial length into at least two circumferential subareas. Then an actual transfer characteristic curve for each subarea is determined and each actual transfer characteristic curve is compared by computation with a predetermined desired printing characteristic curve to find a deviation of the actual transfer characteristic curve from the desired characteristic curve of each subarea. The method further includes calculating a correction to compensate for each deviation; receiving a digital image data in a first data format using the raster image processor, the first data format independent of the printing press; converting the digital image data into machine-specific image data using the raster image processor, the machine-specific image data including the position and the tonal value in the form of a bitmap; applying the correction for a predetermined desired printing characteristic curve for the edition print to the machine-specific image data using the raster image processor; and supplying the machine-specific image data using the raster image processor to the imagesetting unit.
