Abstract

U radu je rađeno istraživanje kojim se prikazuje utjecaj različitih udjela obnovljive

sirovine na karakteristike recikliranih vlakanaca. Reciklirali su se ofsetni, nepremazani

papiri gramature 100g/m², otisnuti Eco Chromos bojom sa dvije vrste fonta, Arial i

Times New Roman, različitih veličina i razmaka između redova. Nakon reciklacije su

se mjerili broj, veličina i površina zaostalih čestica bojila na laboratorijskim listovima,

načinjenim iz različitih faza reciklacije, kao i njihova svjetlina.

Za ispitivanje kvalitete dobivenih uzoraka nakon reciklacije, korištene su optičke

metode, a rezultati su promatrani i analizirani, nakon čega su doneseni određeni

zaključci.

U radu je objašnjena teorija ofsetnog tiska i procesa reciklacije. Objašnjena je

razlika između konvencionalnih ofsetnih boja i boja na bazi vegetabilnih ulja, utjecaj

ofsetnog tiska na okoliš te postupak i kemizam deinkinga.

Svrha rada bila je procijeniti razliku u kvaliteti dobivenih laboratorijskih listova

nakon reciklacije u ovisnosti o vrsti i veličini fonta u ofsetnom tisku.

Abstract (english)

In this work was researched the infl uence of renewable materials on characteristics of

recycled fi bers. 100 g/m² off set, uncoated papers was recycled. Th ey where printed

with Eco Chromos off set ink, with two kinds of font style, Arial and Times New

Roman, with diff erent font sizes and spacing between rows. After recycling, count,

size and surface of ink particles remains on the laboratory sheets, as well as they’re

brightness, was measured.

For quality analysis of recycled papers was used optical methods, and results were

analyzed observed and concluded fi nally.

Th eory of off set printing and recycling process is shown in this work. Th e diff erence

between conventional off set ink and vegetable oil off set ink is explained, as well as

infl uence of off set printing on the environment also as process and chemistry of

deinking.

Th e point of this work was seeing the diff erence in quality of recycled laboratory

sheets depending on font size and style in off set printing.
