  • FIG. 13 shows a modification of the exemplary embodiment of FIG. 2, in which a continuous motif opening 140, here also in the form of a maple leaf, is arranged within the motif area 30.
  • the shape of the motif opening 140 may in particular, as in FIG. 13, be in a sense context with the shape of the motif area 30 and / or the shape of the see-through area 12.
  • FIG. 14 An embodiment according to an embodiment of the invention, which is related to the design described in FIG. 9, is shown in FIG. 14 in plan view and in FIG. 15 in a detail area at the transition from the motif area to the see-through area.
  • FIGS. 14 and 15 includes a see-through area 150 which has both a cut-line grid of parallel cut lines 152 with a colored border 154 outside the motif area 160 and a mark line grid of parallel marking lines 156 that are parallel to the cut lines 152 of the cut line grid.
  • both the marking lines 156 and the cutting lines 152 in perfect registration pass over into pure marking lines 162, as already explained in connection with FIG. 9.
  • the two line types 152, 156 of the see-through area are arranged alternately, but other sequences, for example of two cut lines 152 and one marking line 156, are also conceivable. Since the marker line grid contains no cut lines, it can also be arranged at any angle to the cut line grid.

Abstract

L'invention concerne un support de données, en particulier un document de valeur, tel que billet de banque, carte d'identité et analogue, comprenant un support (20) dans lequel est formée, par une trame linéaire composée d'une pluralité de lignes transversales parallèles (22), une zone transparente (12).
