Abstract

Un lámina transparente se encuentra provista a ambos lados con una disposicion lenticular (4, 6). Los grabados (7) de al menos una de lasdisposiciones (6) tienen un corte transversal mostrando al menos dos curvas(11- 14), con eso mejorandol a visibilidad del patron Moiré formado por las dosdisposiciones. La lámina puede ser usado como una marca contra las falsificaciones.A transparent sheet is provided on both sides with a lenticular arrangement (4, 6). The engravings (7) of at least one of the arrangements (6) have a cross-section showing at least two curves (11-14), thereby improving the visibility of the Moiré pattern formed by the two arrangements. The sheet can be used as a mark against counterfeits.
