Oraz:
Security documents containing a UV security feature are normally made from paper that is ’optically dull’ - i.e. paper that does not contain optical brightening agents (OBAs), which are used in papers to make them look whiter under visible light- because, otherwise, the UV fluorescence of the security feature is made less distinctive by the UV response of the OBAs. Because it is relatively unusual, making paper without OBAs adds to the cost of the paper used in security documents. When the strip has a varnish including an IR up-converter, the need for paper without OBAs is eliminated, as the strips are easily
detectable even in papers with very high background fluorescence. Thus, advantageously, in some example embodiments of the present invention, the strips exhibit both fluorescence under UV light and emissions due to IR up-conversion,
enabling use of the same kind of strip in both optically bright and optically dull security papers.
