Abstract

U većini tiskarskih tehnika obojenje u tisku nije konstantan parametar. Navedeni

problem još je bitniji u tisku ambalaže gdje prodaja nekog proizvoda može ovisiti

o kvaliteti obojenja u tisku.

U ovom diplomskom radu istraživala se realna proizvodnja u tisku na kartonskim

podlogama. Mjereni uzorak, ambalaža proizvoda, ima strogo defi niranu boju po

PANTONE skali koja je univerzalna i jednaka svugdje u svijetu. Izvršena su spektrofotometrijska

mjerenja na otisnutim arcima i to na više pozicija ovisno o zonama

i udaljenosti od čeonih marki te je zatim izračunata razlika boja (ΔE). Rezultati

mjerenja prikazani su tabelarno i u trodimenzionalnom CIE L*a*b* sustavu te su

međusobni odnosi uspoređivani s ciljem da se zaključi da li su obojenja unutar propisanih

standarda i postoji li potreba za povećanom kontrolom kvalitete u tisku.

Abstract (english)

In most printing techniques inking in the press is not a constant parameter. The

above problem is even more important in packaging printing, where sales of a

product may depend on the quality of the inking in the press.

This thesis investigated the real output in print on cardboard. Measured sample,

packaging products, has a strictly defi ned by PANTONE color scale that is universal

and equal everywhere in the world. Spectrophotometric measurements were

carried out on printed sheets and in several positions depending on the zones

and distance from frontal brands and was then calculated color difference (ΔE).

The measurement results are shown in tabular form in the three-dimensional

CIE L*a*b* system and the relationships compared in order to conclude whether

the coloration within the prescribed standards and the need for increased quality

control in the press
