Abstract

Cilj istraživanja ovog diplomskog rada jest analizirati kvalitetu ofsetnog tiska praćenjem

zonskih devijacija reflektivnih karakteristika boja u tisku mjerenjem gustoće obojenja u tri

zone kroz nakladu. Zadatak istraživanja je utvrditi u kojoj mjeri zonske devijacije u gustoći

obojenja utječu na ukupni pad kvalitete tiska te kolika su odstupanja u gustoći obojenja između

pojedinih procesnih boja na istom arku te na istoj zoni kroz cijelu nakladu. Usporedbom

dobivenih rezultata sa standardima propisanim od strane istraživačkih instituta utvrdit ćemo

da li je ispitivana naklada vođena u skladu s propisanim standardima koji nam osiguravaju

kvalitetan otisak.

Teorijski dio rada obuhvaća kratki povijesni pregled razvoja ofsetne tehnike, njezin princip

otiskivanja, način dobivanja višetonske reprodukcije te metode za praćenje i kontrolu kvalitete

tiska kao i faktore koji utječu na pad kvalitete tiska. Analiza kvalitete otisaka u ovom radu

zasniva se na praćenju gustoće obojenja i prirasta restertonskih vrijednosti.

Abstract (english)

The purpose of research in this thesis was to analyze the quality of offset printing by monitoring

zone deviations of press color reflective characteristics by measuring their color density

across three zones throughout one edition. The object of research is to determine what kind

of impact the zone deviations of color density have on total loss of quality in press and how

big are those zone deviations between colors on one sheet and across one zone throughout

the whole edition. Comparing our results with standard values assigned by research institutes

we shall determine if the analyzed edition was led according to the assigned standards which

assure quality in press.

The theoretical part of this work covers the short historical overview of offset printing,

offset printing technique, the method of getting four-color image and means for monitoring

and controlling quality in press as well as elements that cause loss in print quality. The quality

analyzes were achieved by monitoring the color density and dot gain.
