Abstract

A process and apparatus for gravure printing of an image using an erasable and reusable gravure form including a gravure blank form having a base screen which is designed for accommodating a maximum amount of ink to be transferred. The depressions of the base screen of the gravure blank form are uniformly filled with a liquefiable substance using an applicator device and material is then removed from the depressions in conformity with the intended image using thermal energy applied by an image-point transfer device. The printing form is then linked using an inking system and, finally, is regenerated after the printing process to produce a gravure blank form, wherein the depressions of the base screen are again filled in a uniform manner.
