Abstract
The recording of half-tone images by electrophotographic and electrographic recording processes can easily be controlled by a method of altering the gradation in electrostatographic recording of latent charge images of half-tone originals wherein a first latent charge image produced on a primary recording material is recorded as a second latent charge image of altered gradation on a secondary recording carrier by means of a charging current which is controlled by a slotted diaphragm.
