Abstract
In printing form production with electron beams, the imaging scale of the electron source on the source of the printing form is modulated gradation-dependent for engraving different cup geometries. The power density distribution in the effective point of the electron beam can then be approximately rectangular for all gradations. In particular, engraving the small cups, which was hitherto a vertical factor, is thus stable.
