Abstract
To generate engraving data (6), especially for an engraving cylinder, based on a vectorized printer's copy (1) and a screen stipulation (2), depending on the geometry of the elements contained in the printer's copy, within predefined variation range for the engraving data (6) at least one working screen (4) is chosen which deviates from the screen stipulation (2). In the printer's copy (1) first at least one line element is chosen. Afterwards within the variation range a working screen is determined which is matched to the periodicity of the determined line element with respect to density and/or angle. Then in the printer's copy (1) font elements are chosen and they are matched to the working screen using font hinting data. If necessary also the screen geometries which belong to the different process colors are stretched or flattened in the line direction and/or in the advance direction in order to be aligned to the chosen line element.
