Abstract
In a method for engraving printing cylinders in an electronic engraving machine, printing densities are matched in individual engraving lanes by engraving cups in the printing lanes with which the prescribed characteristic rated printing densities are to be achieved. The actual printing densities are identified by measurement after the printing. A corrected lane calibration is derived for the respective engraving lane from deviations between the rated printing densities and the actual printing densities. The allocated corrected lane calibration is applied in the engraving lanes.
