Abstract: Die Erfindung betrifft ein Dokument (100) mit einer Guilloche. Das Dokument (100) umfasst ein Substrat (101), welches eine Mehrzahl von mit einer Druckfarbe flächig bedruckten Flächenabschnitten (103a-d) aufweist. Benachbarte Flächenabschnitte (103a-d) sind durch linienförmige Farbaussparungen (105a-i) voneinander getrennt. Die linienförmigen Farbaussparungen (105a-i) formen eine negative Guilloche, welche frei von der Druckfarbe ist. Voneinander unterschiedliche Linienbreiten (207) sind möglich, sowie linienförmige Farbaussparungen, die mit einem abnehmenden Abstand zueinander verlaufen, ohne einander zu schneiden. Die Druckfarbe kann lichtreflektierende Pigmente, insbesondere UV-Licht-reflektive Pigmente oder IR-Licht-reflektive Pigmente aufweisen.

Abstract: The invention generally relates to a security sheet or document having one or more enhanced watermarks. In one exemplary embodiment, the inventive security sheet or document is a single-ply paper that is made up of a paper layer including one or more watermarks, and a micro-optic security device (e.g., a patch or thread) that at least partially covers an upper or face portion of the watermark(s). The overlying patch or thread increases the durability of the watermark(s), thereby allowing for the watermark(s) as well as reduced fiber density areas therein to be made larger, and further allowing for the reduced fiber density areas to be made thinner. In a preferred embodiment, the micro-optic security device projects one or more synthetic images that coordinate or link in with the watermark design(s). In a more preferred embodiment, the micro-optic security device offers a machine detectable/readable feature in the form of enhanced IR-brightness, especially when measured in transmission. As will be readily appreciated, the inventive security sheet or document offers greatly improved counterfeit-resistance.
