SECURITY STRUCTURE COMPRISING A TRANSPARENT VARNISH AND ASSOCIATED METHOD |
摘要 |
A security element for integration into a document. The security element has a transparent substrate. An array of lenses is disposed on the first side of the substrate. A field of elementary patterns observable through the array of lenses is disposed on the second side of the substrate. A transparent lacquer partially covers the array of lenses. The lacquer takes the form of at least one macroscopic pattern, which locally cancels out the effect of the lenses, thereby allowing an observation of the field of underlying elementary patterns tin halftone. The macroscopic patterns are not spatially coordinated with the field of elementary patterns. |
