Abstract

U grafičkoj industriji ambalaža je trenutno jedan od najčešćih proizvoda. Složive kartonske kutije većinom se upotrebljavaju u prehrambenoj i farmaceutskoj industriji te kao grafički proizvod zahtijevaju vrhunsku kvalitetu (mehaničku i vizualnu). Upravo zbog zahtjeva za zadovoljenja vizualnog kriterija u njihovoj proizvodnji primjenjuje se ofsetna tehnologija otiskivanja koja daje visoko kvalitetne otiske. Tiskovna podloga i tiskarsko bojilo pritom imaju vrlo bitnu ulogu. U ovom diplomskom radu kao suvremene tiskovne podloge korišteni su ekološki karton od jadranskih algi i kartoni na bazi jednogodišnjih biljaka koji ne sadržavaju tradicionalna vlakanca iz drvne sirovine. Svi su oni komparirani u odnosu na standardni sjajni premazani karton koji je ujedno i najučestalija tiskovna podloga. Trend primjene novih, ekološki prihvatljivijih bojila uvelike utječe i na rezultate krajnje kolorne reprodukcije. Riječ je bojilima kojima je povećana pigmentacija i smanjen udio štetnih mineralnih ulja. Ispitivanjem i analizom uzoraka dani su korekcijski faktori kojima se u procesu pripreme i tiska može utjecati na krajnji otisak kako bi isti bio što kvalitetniji, a u skladu s tim, i privlačniji krajnjem korisniku. Najveći gamut reprodukcije ostvaren je na standardnom kartonu Kromopaku Express bojilom (V=769,934). Najbolji gamut od ekoloških papira ostvaren je na Echo kartonu sa Diamond bojilom (V=300,647). Najlošiji raspon reprodukcije ostvaren je na Alga Carta kartonu Diamond bojilom (V=264,177).

Abstract (english)

Packaging products are, at the moment, one of the most common in graphic industry. Folding cardboard boxes are mostly used in food and pharmaceutical industry. This graphic product has to meet most demanding standards in mechanical and visual quality. Because of the these standards offset technology is used in production. Printing substrate and colours are very important parts in that process. In this thesis modern process which uses bio carboard (made out of adriatic algees) an cardboars based on one year plants is studied. They are all compared in relations to standard shiny coated carboard which is most used in this industry. Trend of using new, eco friendly, diyes influences greatly on final results of color reproduction. These are diyes which have increased pigmentation and reduced amount of mineral oils. Analysys of mentioned paper and graphic colours gave us correction filters which are intended to enhance qualtiy of the final product and make it more attractive to potential user. The largest gamut reproduction was achieved on a standard cardboard Kromopak with Express ink (V = 769.934). Best gamut of ecological paper realized the Echo card with Diamond ink (V = 300.647). Worst playback range was achieved on Alga Carta cardboard with Diamond ink (V = 264.177).
