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 …

Why it's free to use
- Filed March 27, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 27, 2023.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
