Abstract

Konkurentnost tržišta, sve veći zahtjevi klijenata te napredak tehnologije navodi tiskare

da prate trendove i s konvencionalnih tehnika otiskivanja prelaze na novije tehnologije

visokokvalitetnog tiska. Bezvodni ofsetni tisak kao jedna takva tehnika uveden je 1980-

ih godina kao realna alternativa konvencionalnom ofsetnom tisku i fleksotisku u

kvalitetnijoj, jednostavnijoj i bržoj izvedbi tiska. Odsustvom otopine za vlaženje pri

procesu tiska postižu se oštrina otisnutih rasterskih elemenata čišćih boja, brži početak

tiska i manje otpada. To je izrazito važno kod samoljepivih vinskih etiketa jer se one

tiskaju na najrazličitijim podlogama, od izrazito grubih pa sve do glatkih i sjajnih

podloga. Isto tako, kod etiketa se nameću sve veći zahtjevi za kvalitetnim otiskivanjem

sićušnih detalja te većih punih površina procesnim, spotnim i metaliziranim bojama,

stoga se u ovom radu uspoređuje kvaliteta etiketa otisnutih u konvencionalnom i

bezvodnom ofsetu. Navedena kvaliteta naročito se očituje u reprodukciji malih i velikih

rastertonskih vrijednosti, kada zbog različitih reprodukcijskih ograničenja dolazi do lošije

reprodukcije tih istih elemenata.

Abstract (english)

Market competition, increasing customer demands and technology progress urge printers

to keep up with trends and switch from conventional printing techniques to new, highquality printing technologies. Waterless offset printing as one of these techniques was

introduced in the 1980s as a convenient alternative to conventional offset printing and

flexo printing in a better, simpler and faster printing performance. The absence of the

dampening solution in the printing process increases the sharpness of the printed raster

elements, enables cleaner colours, a faster start of printing process and minimizes the

waste. This is especially important for self-adhesive wine labels, as they are printed on a

variety of substrates, from rough to smooth and glossy substrates. Furthermore, the

demand for quality printing of tiny details and larger full surfaces, spot and metallic

colours increases, so the aim of this master thesis is to explain and compare the quality of

labels printed by means of conventional and waterless offset. The quality is clearly

manifested in the reproduction of small and large halftone values, when, due to various

reproduction limits, the reproduction of these elements is of poorer quality.
