Title (EN) DOCUMENT OF VALUE AND METHOD FOR DETECTING SOIL LEVEL
(FR) DOCUMENT DE VALEUR ET PROCÉDÉ DE DÉTECTION DU NIVEAU DE SOUILLURE
Abstract: front page image
(EN)A document of value is provided comprising a soil level test feature for determining whether the document of value is soiled. The soil level test feature comprises: a reference area comprising a first region of the document; and a measurement area comprising a second region of the document. The reflectance of the measurement area is affected differently by the presence of soil or wear to that of the reference area, such that the difference in reflectance between the reference area and the measurement area provides an indicator of the degree of soiling of the document of value.
(FR)L’invention concerne un document de valeur doté d’une fonction de test du niveau de souillure permettant de déterminer si ledit document de valeur est souillé. Cette fonction de test du niveau de souillure comporte : une zone de référence composée d’une première partie du document et une zone de mesure composée d’une deuxième partie du document. La réflectance de la zone de mesure est différente de celle de la zone de référence en raison de la présence de souillure ou d’usure, de telle sorte que la différence de réflectance de la zone de mesure et de la zone de référence constitue un indicateur du degré de souillure du document de valeur.
