Abstract
A secure multi-layered structure (14), for example, for a secure document, the secure multi-layered structure comprising a first layer (20) having a first aperture (25) opened in the first layer, a second layer (30) having a second aperture (35) opened in the second layer, and a third layer (40) having a third aperture (45) opened in the third layer, wherein each layer at least partially overlaps with the layer adjacent to it, at least a portion of the third layer being visible through the first aperture.
Claims13
A method for producing a secure multi-layered structure, the method comprising:
- providing first, second, and third sheets, each of the first, second, and third sheets comprising at least one of a laser-engraved region or printed region;
- punching a first aperture in the at least one of the laser-engraved region or printed region of the first sheet;
- punching a second aperture in the at least one of the laser-engraved region or printed region of the second sheet, the contour of the second aperture configured to be contained within the contour of the first aperture when superimposed;
- punching a third aperture in the at least one of the laser-engraved region or printed region of the third sheet, the contour of the third aperture configured to be contained within the contour of the second aperture when superimposed;
- and
- laminating the punched first, second, and third sheets by aligning them so that each sheet overlaps at least partially with the sheet adjacent to it, the third sheet being at least partially visible through the first aperture.
