Abstract
Za postizanje vrhunske kvalitete reprodukcije uz standardne CMYK boje potrebno je i dodatno otiskivanje specijalnih bojila. Jedna od postojećih digitalnih tehnika tiska koje to mogu postići je elektrofotografija s tekućim tonerom. Kromatski gledano najčešće se dodaju narančasta i ljubičasta (IndiChrome tisak). U ovom radu detaljno će biti analiziran utjecaj šesterobojnog otiskivanja na kolornu reprodukciju, te će se definirati porast kvalitete reprodukcije korištenjem većeg broja separacija u elektrofotografskom tisku. Studija će biti koncipirana tako da se potpuno raščlane otisnute površine, odnosno definirati kako dodatne boje utječu na reprodukciju: punih tonova (CIELAB ΔE, mottling i gamut reprodukcije), rastriranih površina (CIELAB ΔE rasterskih elemenata i motling rastrirane površine) i mikro elemenata (mikrotekst). Na razliku u reprodukciji utječe i tiskovna podloga. Zbog toga su korištene dvije karakteristične tiskovne podloge: papir za umjetnički tisak Magno star Gloss i naravni papir Maxio set. Spektrofotometrijskim i kolorimetrijskim mjerenjem vidljivo je da će dodatne boje znatno poboljšati kvalitetu reprodukcije.

Abstract in english: | To achieve the highest quality reproduction with standard CMYK colors it is necessary to add special printing colors. One of the existing digital printing techniques, which can achieve that, is a liquid toner electrophotography. Chromatically observed, usually added colors are orange and purple (IndiChrome printing). In this thesis it will be analyzed the impact of six-color printing on a color reproduction and will be defined possible benefit achieved by using a larger number of separations in electrophotographic printing. The study will be designed to define how the additional colors affect reproduction: a full tones (CIELAB ΔE, mottling and gamut reproduction), halftone surface (CIELAB ΔE of halftone elements and mottling of halftone surface) and micro elements (micro font). On the difference in reproduction also affects printing substrate. Therefore are used two typical printing substrates: paper for art prints Magno Star Gloss and natural Maxio set paper. With spectrophotometric and colorimetric measurements it is evident that additional colors significantly improve the quality of reproduction. |
