Abstract

Zaštitni tisak obuhvaća korištenje različitih elemenata i njihovih kombinacija koje smanjuju mogućnosti da neki proizvod bude nezakonito promijenjen ili umnožen. Jedan od često korištenih zaštitnih elemenata u tisku je zaštitno bojilo, a predmet ovog diplomskog rada je UV fluorescentno bojilo. U teorijskom dijelu rada objašnjen je pojam zaštitnog tiska te princip na kojem djeluje ova vrsta bojila. Istražen je vizualni doživljaj različitih kombinacija papira i fluorescentnih bojila. Korišteni su ofsetni papir i papir za umjetnički tisak, te plava i žuta UV fluorescentna boja. Otisci su napravljeni na uređajima IGT i K Hand Coater kako bi se dobio što širi raspon debljina nanosa bojila koje su kasnije vizualno ocijenjene. Rezultati su predočeni grafikonima, a na osnovu njih doneseni su i zaključci o kvaliteti otisnutih kombinacija tiskovne podloge i bojila.

Abstract in english:	Security printing includes the use of different features and their combinations that make illegal alternation or duplication of a document less possible. One of the security features that are frequently in use is security printing ink, but the focus of this paper is on UV fluorescent ink. Definition of security printing and properties of this type of inks are given in the theoretical part of this paper. Also, the visual aspect of different paper and fluorescent ink combinations was analyzed. Used materials are paper for offset printing, kunstdruck paper and blue and yellow UV fluorescent inks. Prints were made with IGT and K Hand Coater devices in order to obtain wider range of ink thicknesses that were visually evaluated. Results are visualized, and conclusions about quality of ink and printing substrate combinations are given on their basis.
