The present invention relates to the field of processes for producing a security feature on a substrate by an intaglio printing process comprising a step a) of inking an intaglio engraved printing plate with an oxidative drying intaglio ink, said intaglio engraved printing plate being at a printing plate temperature between about 45° C. and about 85° C.; a step b) of wiping off any excess the oxidative drying intaglio ink using a paper of a tissue wiping system or using a polymeric wiping cylinder and cleaning said polymeric wiping cylinder with an alkaline aqueous wiping solution in combination with one or more mechanical means; a step c) of transferring said oxidative drying intaglio ink in the form of the security feature on the substrate; and a step d) of drying the oxidative drying intaglio ink in the presence of air so as to form the security feature.
