Abstract

U ovome radu ispitivanja su provedena tako da se otisnula testna forma u ve oj nakladi u realnim uvjetima na proizvodnom stroju. Ispitivanja su provedena na elementima testne forme s kojima je mogu e izra unati prirast rastertonskih vrijednosti, ustanoviti oscilacije gusto e obojenja i CIE L*a*b* vrijednosti sivog balansa te s kojima je mogu e ustanoviti vizualnu kvalitetu tiska. Vizualna kvaliteta tiska ustanovljavana je na razli itim profilima vi ebojnih slika. Uzorci za ispitivanje uzimani su iz razli itih dijelova naklade te je uzeto dvadeset razli itih uzoraka iz naklade od 13.000 otisaka. Otiskivanje je obavljeno po tivaju i preporuke me unarodnih ISO standarda. Na temelju znanstvene analize odvojenih uzoraka dobiveni su odnosi gusto e obojenja i prirasta rastertonskih vrijednosti te je ustanovljena oscilacija sivog balansa kroz cijelu nakladu. Isto tako dana je preporuka o kori tenju profila za vi ebojne slike kao i preporuka tolerancije gusto e obojenja kroz nakladu, a koja nije propisana me unarodnim standardom. Sintezom rezultata istra ivanja dobivena su nova saznanja o kvaliteti novinskog tiska.

Abstract in english:	In this paper, tests were made so the test form was printed in larger circulation in real conditions on printing machine. Tests were performed on the elements of the test forms where it was possible to calculate the dot gain of screen value, to determine the density fluctuations in coloration and CIE L* a* b* values of the gray balance, and with whom it is possible to establish a visual print quality. Visual perception of print quality on different profiles was made on half-tone images. Specimens were taken from different parts of the circulation and samples were taken from twenty different runs of 13000 prints. Printing was done respecting the recommendations of the international ISO standards. Based on scientific analysis of separate samples the density of coloration and dot gain was obtained and oscillations of the gray balance throughout the print run were found. Also the recommendations of profiles for half-tone colour images as well as the recommendations of tolerance density that is not prescribed by international standards were given. Synthesizing research results gave new findings about the quality of newspaper printing.
