Abstract

Visokopigmentirane boje imaju mogućnost s tanjim slojem boje prekriti rasterske elemente pri čemu je intezitet njihova obojenja veći u odnosu na klasične boje. Upotrebom takvih boja otisci dosegnu točku gdje se prirast rastertonske vrijednosti i prostor reprodukcije mijenja, a koja je usko povezana s granicama kvalitete otiska. Ovo je također izravno povezano sa standardizacijom tiska i ponovljivosti tiskarskog procesa. Upravo zbog toga naše istraživanje smo usmjerili na povećanje kvalitete reprodukcije upotrebom visokopigmetiranih boja. Otiskivanje je provedeno na dvije vrste papira koji se najčešće koriste u tehnici ofsetnog tiska. U ovome radu, kvaliteta reprodukcije vizualno je ispitivana s promjenjivim vrijednostima gustoće obojenja, prirastom rastertonskih vrijednosti i gamutu boja. Ovaj rad sadrži također i nove, preporučljive vrijednosti prirasta rastertonske vrijednosti i prostora reprodukcije boja kada se otiskivanje obavlja korištenjem visokopigmentiranih boja.<br />Highly pigmented inks have the ability to cover screen elements with a thinner layer of ink applied whereby the intensity of their inking is higher compared to the classical inks. When using such inks, the printing reaches the point where the ink dot gain and the space of reproduction changes, which is closely related to the limits of the print quality. This is also directly related to the standardization of the print and the repeatability of the process. For this reason our research is focused on increasing the reproduction quality by using highly pigmented inks. The printing was carried out on two types of paper that were most commonly used in offset printing technology. In this paper, the reproduction quality was visually determined at changeable values of the inking densities, dot gain and gamut of colour. This paper also contains the new, recommended values of dot gain and gamut for printing processes using highly pigmented inks.
