Abstract

Razvoj tehnologije tiska omogućio je otiskivanje višebojnih trodimenzionalnih objekata. Otiskivanje je izvršeno na 3D pisaču u boji Zprinter Spectrum 510 koji radi na principu ink-jet pisača. 3D objekti su građeni od kompozitnog materijala temeljenog na prahu i vezivu koji je sposoban izraditi oblike kompleksne geometrije. U ovom diplomskom radu istraživani su utjecaji različitih izvora svjetlosti na gamut trodimenzionalnog objekta. Proces grafičke reprodukcije uvjetuju različiti parametri, a jednog od najbitnijih predstavlja konverzija boja iz izvornog prostora u željeni prostor i stoga je cilj ovog diplomskog rada prikazati mogućnosti reproduciranja boje na površini objekta. U ovom radu izvršena su optička mjerenja na obojenoj površini 3D objekta pri utjecaju različitih izvora svjetlosti i zatim su uspoređeni njihovi međusobni odnosi. Rezultati mjerenja prikazani su tabelarno i slikama a*b*, a*L* i b*L*, CIE L*a*b* sustava boja.

Abstract in english:	In this thesis, a research of the influence of various light sources upon the gamut of a three-dimensional object has been conducted. The advances in print tehnology made the printing of 3D objects possible. The printing was done using a 3D color printer Zprinter Spectrum 510, which is based on the ink-jet tehnology. The models are made out of powder and binder based composite material capable of shaping complex geometry forms. The process of graphic reproduction in conditioned by various parameters, one of the most important being the conversion of colors from the original area into desired one. Therefore, the goal of this thesis is to describe the possibility of reproducing colors on the surface of an object. In this paper we performed optical measuring on the printed surface of a 3D object, while it was subjected to different light sources, and afterwards compared the relations betwee the results, which are shown in tabels and graphically in CIE L*a*b* color system.
