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 (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.
