Abstract

Da bi se postigla viša kvaliteta grafickih proizvoda standardne otiske potrebno je lakirati.

Nanosom laka promjeniti ce se površina otiska, a samim time i kolorne vrijednosti. U

ovom završnom radu izvršeno je hibridno otiskivanje otisaka kombinacijom

elektrofotografije i Ink Jeta. U radu su analizirani otisci lakirani na tri razlicita tipa papira

(papir za umjetnicki tisak Chorus lux, kalindrirani papir Splendogel i ofsetni papir

Masterprint). Eksperimentalni otisci tako su nastali otiskivanjem na elektrofotografskom

HP Indigo stroju S 5500 (koji primjenjuje tekuce electroink bojilo) koji su dotisnuti

razlicitom kolicinom UV sušeceg laka. Pritom je korišten Ink-Jet Roland UV LEC 300.

Cilj ovog rada je utvrditi vrijednosti kolornih promjena nastalih tijekom nanašanja UV laka

u razlicitoj površinskoj pokrivenosti ( 33%, 66%, 100% RTV), pri cemu su istražene

promjene kolornih gamuta (DV). Za detaljnjiju analizu izracunata je razlika u obojenju DE00

karakteristicnih tonova (CMYK RGB) u punom tonu i 50% rasteru.

Abstract (english)

In order to achieve a higher quality of printed products standard prints are being varnished.

Varnish will change the surface of the prints, and therefore their colorimetric values. In this

study prints were made by a hybrid combination of electrophotography and Ink Jet. Prints

were analyzed on three different types of paper (paper for art printing Chorus lux,

calandered Splendogel paper and offset paper Masterprint). Experimental prints were

created by printing on the electrophotographic machine HP Indigo S 5500 (which applies

liquid ElectroInk toner), then the prints were varnished with different amounts of UV

varnish with Ink-Jet UV Roland LEC 300. The goal of this study was to determine the

value of color changes that occurred during coating with UV varnish at different surface

coverage (33%, 66%, 100% RTV), where they were explored the changes of the gamut

(DV). For a detailed analysis we calculated the difference DE00 of the distinctive colours

(RGB CMYK) in the full tone and 50% raster.
