Abstract

Starting from a blank gravure form, a filling step and a subsequent imaging step are carried out to produce a printing form. In the filling step, depressions are evenly filled with a UV printing ink by an application device, and the UV printing ink is then solidified by a UV drier. In the imaging step, solidified UV printing ink is removed from the depressions in accordance with the image by thermal ablation. The gravure form screened in accordance with the image is then inked with UV printing ink by an inking system. For reuse, the gravure form undergoes an erasure step that uses UV printing ink.
