Abstract: The invention provides a structure comprising: a fiber layer; a sub-structure including a translucent region; a watermark or pseudo-watermark carried by the fiber layer and superposed at least in part with the translucent region of the sub-structure, such that, in the translucent region of the sub-structure, the watermark or pseudo-watermark is observable in light transmitted through the structure only from the face of the structure that is adjacent to the fiber layer; and an integrated microcircuit device for communicating with or without contact.

Abstract: A process for producing a printed smart card. The process includes applying a metallic ink on a first surface of a core of the smart card and coating only a portion of the metallic ink with a varnish. The process further includes laminating an overlay layer on the first surface after the applying the metallic ink and coating only the portion of the metallic layer with the varnish.

Abstract: The invention relates to a method for manufacturing a smart card that has a printed surface with a tri-dimensional effect. The method includes applying a metallic ink on at least one surface of at least one plastic layer, coating at least partially said metallic ink with a varnish, laminating an overlay layer on the printed layer. Thus, the lamination of an overlay layer above the printed layer results in a difference in aspect between the metallic ink, which remains brilliant, and the varnish, which becomes dull, and, thus, contributes to obtain the required three-dimensional visual effect. Moreover, the overlay allows the smart card to achieve a flat surface.
