Abstract
The aim of the invention is to further improve the ablation precision in terms of structuring the depressions of the basic grid of a gravure printing form and the printing behaviour of the depressions of a basic grid of an erasable and re-usable gravure printing form, by increasing the uniformity of the base of said depressions. To achieve this, the filler material that fills the erasable, re-usable printing gravure form is removed using laser beams, whose intensity profile over the cross-section of the laser beam corresponds to a pillbox profile.
