Abstract

Fleksotisak je tehnika direktnog visokog tiska koja se koristi u mnogobrojnim ambalažnim

proizvodima za otiskivanje na različite vrste materijala. Razvojem tehnologija izrade

tiskovnih formi i sustava za upravljenje podacima, fleksotisak zauzima svoje mjesto kao

jedna od prominentnih tehnika tiska koje preuzimaju tržište. Većim stupnjem standardizacije,

novim tehničkim rješenjima kod konstrukcije strojeva i bržim radnim procesom, povećava se

kvaliteta otiska ali i ekonomska učinkovitost.

U ovom diplomskom radu cilj je istražiti mogućnosti pobojšanja optičkih i mehaničkih

svojstava otisaka s dodatkom nanočestica u tehnici fleksotisak. U radu je korištena

komercijalna tiskarska boja u koju su dodane nanočestice u različitim koncentracijama. Radi

istraživanja utjecaja ubrzanog starenja na promatrana svojstva otisaka, dobiveni uzorci su

podvrgnuti ubrzanom starenju u trajanu od 12 i 24 sata te su na njima dodatno provedena

mjerenja optičkih i mehaničkih svojstava. Pretpostavljeno je da će dodatak nanočestica, u

različitim koncentracijama, u osnovnu tiskarsku boju, omogućiti dobivanje tiskarske boje i

otisaka s novim, poboljšanim svojstvima.

Abstract (english)

Flexographic printing is a direct letterpress printing technique used in packaging industry for

printing on different types of materials. With the development of the latest printing

technologies, flexographic printing is taking its place as one of the prominent printing

techniques that is taking over the market. With a higher degree of standardization, new

technical solutions for machine constructions and faster work process, the quality of the print

increases, as well as the economic efficiency.

In this thesis, the aim is to research the possibilities of improving the optical and mechanical

properties of prints with the addition of nanoparticles in the technique of flexographic

printing. For this paper the commercial printing ink was used to which nanoparticles were

added in different concentrations. In order to research the influence of accelerated aging on

the observed properties of the prints, the obtained samples were subjected to accelerated

aging for 12 and 24 hours, and measurements of optical and mechanical properties were

additionally performed on them. It was assumed that the addition of nanoparticles, in

different concentrations, to the basic printing ink would enable the production of printing ink

and prints with new, improved properties.
