CA 2476219

The invention relates to a method for producing a plate, in particular a licence plate for a motor vehicle. The inventive method consists in applying at least a range of layers which form a flat electrolumeniscent condenser (4, 5, 6, 7) and a reflecting film (10,10'). Said film is selected in such a way that the reflecting power thereof is higher than a legally authorised value. Said reflecting power is afterwards reduced during further production in such a way that it is lower than the legally authorised value.

L'invention concerne un procédé de production d'une plaque, en particulier d'une plaque d'immatriculation de véhicule automobile. Ce procédé consiste à appliquer sur un support (1) au moins une série de couches qui forment un condensateur plat électroluminescent (4, 5, 6, 7), ainsi qu'une feuille réfléchissante (10 ; 10'). Cette feuille réfléchissante (10 ; 10') est sélectionnée de sorte que sa valeur de réflexion soit supérieure à la valeur maximale légalement autorisée, cette valeur de réflexion étant ensuite abaissée lors des étapes de production ultérieures de façon à se situer en deçà de la valeur maximale légalement autorisée.
