Abstract

Premazani papiri u odnosu na nepremazane papire radi površinski obrađenih slojeva imaju prednost u standardizaciji reprodukcijskih procesa i postizanju mjerljivo kvalitetnih rezultata tiska. S druge strane zahtjevi dizajna (nepremazani papir u funkciji elementa komunikacije sadržaja) i zahtjevi tržišta (nepremazani papiri u funkciji potražnje manje tehnološki obrađenih odnosno prirodnih materijala) opravdavaju primjenu reprodukcijskih procesa upravljanja bojom na nepremazanim papirima, odnosno postavljaju komunikacijsko-ekonomsko-ekološku opravdanost, kako radi kvalitetno usmjerene komunikacije sadržaja reprodukcije, mogućih ušteda grafičkih materijala, jednostavnijih tehnoloških postupaka proizvodnje nepremazanih papira, kako i kasnije jednostavnije tehnološke obrade istih materijala za novu upotrebu. Upravljanje bojom za reprodukciju na nepremazanim papirima može odgovoriti na te zahtjeve uzimajući u obzir, kako specifične zadatosti (ograničenja) nepremazanih papira i svih ukupnih elemenata utjecaja na standardizaciju reprodukcijskih procesa (mjereno denzitometrijsko i spektrofotometrijsko očitanje), tako i ljudskih (optičkih) zadatosti čuvstva vida (razlikovanje 160 tonova i 200 stepenica sivog klina) i na kraju doživljajnog opisa kromatskog i akromatskog dojma. Konkretna ograničenja reprodukcije na nepremazanom papiru uvjetovani su hrapavom površinom na kojoj uvijek postoje veliki prirasti rastertonskih vrijednosti, smanjeni relativni tiskovni kontrast u odnosu na premazane papire, kao i smanjen opseg boje koji se može reproducirati. Standardizaciju provodimo upravljanjem bojom ICC profilima karakteriziranim za upojne nepremazane tiskovne podloge, korekcijskim metodama u pripremnoj fazi, kao i pri optimiziranju debljine nanosa tiskarske boje u tisku.

Abstract in english:	Coated papers compared to uncoated papers for surface treated sheets have a reproductive advantage in the standardization process and achieving measurable quality printing results. On the other hand, the design requirements (uncoated paper operational elements of communication facilities) and market demands (uncoated papers in the demand function less technologically processed or natural materials) justify the reproduction process colour management on uncoated paper or set of communications and economic-ecological justification, to works well targeted communication of reproduction content, possible savings of graphic material, simpler technological methods of production uncoated paper, and later to a simpler technological processing of the materials for future use . Managing colour for reproduction on uncoated papers can respond to these requests, taking into account, in specific givens (restrictions) uncoated paper and the total of all elements affecting the standardization process of reproduction (measured densitometry and spectrophotometric reading) and human (optical) givens feelings vision (distinguish 160 shades of gray and 200 steps of grayscale) and at the end of the experiential descriptions of chromatic and achromatic perception. The specific restrictions on uncoated paper are determined by a rough surface on which there are always large dot gain, reduced the relative printing contrast compared to a print on coated papers, as well as the reduced volume of colours that can be reproduced. Standardization spend colour management ICC profiles characterized for absorbing uncoated printing substrate, the correction methods in the prepress, as well as to optimize the thickness of ink in printing.
