Each graphic represents its own information derived from the following sources: vector graphics, drawing, photograph and textual information. One graphic will be visible to the naked eye after the print. The other graphics will be observed with an NIR surveillance camera. These other graphics are nested into the selected visible graphics. All the graphics together make up a security print product with the characteristics of an individual solution with multilayered elements. Reprinting is possible only for the person in possession of the solution created according to the algorithm based on the INFRAREDESIGN\u00ae method. When these graphics are printed on paper, it is impossible to produce an identical graphic prepress (C, M, Y, K) to produce forgery with the same dual properties in the visible and NIR spectrum.<\/jats:p>","DOI":"10.3390\/info13020047","type":"journal-article","created":{"date-parts":[[2022,1,20]],"date-time":"2022-01-20T22:51:06Z","timestamp":1642719066000},"page":"47","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Security Graphics with Multilayered Elements in the Near-Infrared and Visible Spectrum"],"prefix":"10.3390","volume":"13","author":[{"given":"Jana","family":"\u017diljak Gr\u0161i\u0107","sequence":"first","affiliation":[{"name":"Department of Informatics & Computing, Zagreb University of Applied Sciences, 10000 Zagreb, Croatia"},{"name":"Department of Multimedia, Design and Application, University North, 48000 Koprivnica, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Denis","family":"Jure\u010di\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Graphic Arts, University of Zagreb, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lidija","family":"Tepe\u0161 Golubi\u0107","sequence":"additional","affiliation":[{"name":"Department of Informatics & Computing, Zagreb University of Applied Sciences, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4244-1464","authenticated-orcid":false,"given":"Silvio","family":"Plehati","sequence":"additional","affiliation":[{"name":"Department of Informatics & Computing, Zagreb University of Applied Sciences, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,20]]},"reference":[{"key":"ref_1","first-page":"153","article-title":"Development of a prototype for ZRGB INFRAREDESIGN device","volume":"18","author":"Pap","year":"2011","journal-title":"Tech.
