ABSTRACT:
In the implementation of the method for manufacturing a texture drum, a surface structure is produced in the region of a surface with an electron beam, preceding a charging occurring within a working interval with an electrons beam having an energy density generating a recess, the texture drum is charged during a pre-treatment interval by an electron beam having an energy density that leaves the surface structure essentially as it was formed.
