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 (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.
