A method of producing a printing plate on a cylindrical printing-plate
carrier 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 compared by computation with a predetermined desired
printing characteristic curve for each subarea to find a deviation. The
method further includes calculating a correction to compensate for each
deviation; receiving a digital image data in a first data format using a
raster image processor; converting the digital image data into
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 corrected machine-specific image data to an imagesetting
unit.
