The invention relates to a method for the machine-reading of markings on/in transparent, especially pane-type, marking carriers, especially glass panes, according to which the marking carrier (2) is illuminated with UV light at least during the period of a machine-reading process of a marking, especially by means of a reading device (4), in order to increase the contrast between a marking (5) and the marking carrier (2). The invention also relates to a device for the machine-reading of markings in transparent, especially pane- type, marking carriers, especially glass panes, comprising at least one reading device (4) for markings arranged on/in a marking carrier, and at least one illumination device (4) is provided for increasing the contrast between a marking (5) and the surrounding transparent marking carrier (2) by illuminating the marking carrier (2) with UV light.
L'invention concerne un procédé pour lire par machine des marques se trouvant sur/dans des porte-marques transparents, en particulier des porte-marques transparents en forme de plaque, notamment des plaques de verre. Ce procédé consiste à éclairer le porte-marque (2) à l'aide d'une lumière U.V., au moins pendant un processus de lecture par machine d'une marque, en particulier au moyen d'un dispositif de lecture (4), pour augmenter le contraste entre la marque (5) et le porte-marque (2). L'invention concerne également un dispositif pour lire par marchine des marques se trouvant dans des porte-marques transparents, en particulier des porte-marques transparents en forme de plaque, notamment des plaques de verre. Ce dispositif comprend au moins un dispositif de lecture (4) pour lire des marques se trouvant sur/dans un porte-marque, et au moins un dispositif d'éclairage (4) pour augmenter le contraste entre une marque (5) et la zone environnante du porte-marque (2) transparent, par éclairage du porte-marque (2) à l'aide d'une lumière U.V.
