Abstract

L'invention concerne un procédé de fabrication d'un élément de panneau, d'un élément d'actionnement ou similaire comportant des symboles fonctionnels pour l'éclairage par transmission. Selon l'invention, un élément support transparent (1) est formé de sorte qu'une première structure en relief (7), correspondant à la forme d'au moins un premier symbole fonctionnel (9, 11), soit prévue sur la surface (5) dudit élément support, à l'intérieur d'une première zone prédéterminée. Une première couche colorée transparente (13, 15), de préférence stable thermiquement, est appliquée sur l'élément support (1) dans la première zone prédéterminée. La surface (5) de l'élément support transparent (1), présentant le ou les premiers symboles fonctionnels (9, 11), est recouverte d'un matériau non transparent (17) de sorte que la surface (7a) de la première structure en relief revêtue (7), s'étendant pratiquement parallèlement à la surface (5) de l'élément support (1), demeure sans matériau non transparent (17). L'invention concerne en outre un procédé pour produire un tel élément comportant des symboles fonctionnels de différentes couleurs, ledit procédé consistant à appliquer une ou plusieurs couches de différentes couleurs, côte à côte ou l'une au-dessus de l'autre, sur un élément support. Ce procédé consiste ensuite à recouvrir ces couches colorées avec une couche colorée non transparente et à produire un symbole fonctionnel dans la couleur souhaitée, de sorte que toutes les couches colorées se trouvant au-dessus de la couche colorée souhaitée soient retirées au niveau du symbole fonctionnel à produire.
