There is described a method for varnishing security documents, especially intaglio-printed security documents such as banknotes, wherein both sides of the security documents are covered by a protective varnish. The method comprises the step of applying a thicker layer of protective varnish on a side of the security documents which exhibits a greater surface roughness, espe-cially the side which is opposite to the side of the security documents which was last printed by intaglio printing. Also described in a varnishing machine for carrying out the above method.
On décrit un procédé destiné à vernir des documents sécurisés, en particulier des documents sécurisés imprimés en taille-douce tels que des billets de banque, les deux côtés des documents sécurisés étant recouverts dun vernis protecteur. Le procédé comporte une étape consistant à appliquer une couche plus épaisse de vernis protecteur sur un côté des documents sécurisés qui présente une plus forte rugosité de surface, en particulier le côté opposé au côté des documents sécurisés qui a été imprimé en dernier par impression en taille-douce. On décrit également une machine à vernir destinée à réaliser le procédé ci-dessus.
