Abstract
Zaštitni tisak je važno područje u grafičkoj industriji koje se bavi otiskivanjem proizvoda kao što su novčanice, putovnice, naljepnice, poštanske marke i razni certifikati i vrijednosnice. Glavni cilj tog sektora je sprečavanje krivotvorenja, lažiranja i zlouporabe. U teorijskom dijelu ovog rada objašnjen je zaštitni tisak, pojava krivotvorenja i elementi koji se koriste u svrhu zaštite dokumenata i brojnih proizvoda. U eksperimentalnom dijelu opisane su boje upotrijebljene za otiskivanje na dvije vrste podloga, uređaji korišteni za otiskivanje i mjerenje. Boje koje su se koristile su termokromatska i fotokromatska boja. Uređaji na kojima se boja otiskivala su ofsetni stroj, IGT i K Hand Coater. Brojčane vrijednosti kolorimetrijskih karakteristika utvrdit će se spektrofotometrom. Rezultati ispitivanja bit će prikazani grafikonima, a na osnovu dobivenih rezultata bit će doneseni i zaključci.

Abstract in english: | Security printing is important area in the printing industry that deals with producing products such as banknotes, passports, labels, stamps and various certificates and securities. The main goal of this sector is to prevent counterfeiting, imitation and diversion. In the theoretical part of this paper, security printing, relation to counterfeiting and features used to protect documents and other products are explained. The experimental part describes printing inks used on two types of substrate, devices used for printing and measurement. Inks that were used are thermochromic and photochromic inks. Printing devices are offset machine, IGT and K Hand Coater. Numeric values and colorimetric characteristics are determined by spectrophotometer. Test results are displayed in diagrams. Conclusions are given on the basis of those results. |
