method for improving the quality of a druckformzylinder engraved image

摘要

The method involves engraving small indentations by taking into account geometrical data, both indentation geometry data and tool (4) geometry data, which can vary with tool wear, for corrective adaptation of the actual indentation volume to the desired volume corresponding to a required shade value An especially two-dimensional image of the tool used is formed, from which the geometry is determined. An independent claim is also included for the following: (a) an arrangement for improving the quality of an image engraved on a print forme cylinder.
