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 in 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.
