Abstract

Proizvodnja papira se zasniva na celulozi kao osnovnoj sirovini. Svijest o okolišu i

održivom razvoju dovela je do povećanja uporabe recikliranog papira za ispis. Kako

obnovljena vlakna ne mogu osigurati istu razinu kvalitete proizvoda od papira, upotreba

alternativnih izvora vlakana od velike je važnosti.

U radu je analiziran utjecaj dubine penetracije boje unutar otisnutih laboratorijskih

tiskovnih podloga dobivenih od recikliranih drvnih vlakanaca i nedrvnih vlakanaca na

kvalitetu otiska. Istraživanja su provedena na laboratorijskim tiskovnim podlogama koje

su izrađene miješanjem ne drvnih vlakanaca (pšenice, ječma i pšenoraži) s recikliranim

drvnim vlakancima u različitim masenim omjerima. Uzorci su otisnuti digitalnom

tehnikom tiska UV ink jet. Analiza dubine penetracije boje unutar otisnutih tiskovnih

podloga promatrana je pomoću programa za slikovnu analizu na slikama dobivenim sa

svjetlosnim mikroskopom promatrajući poprečni presjek uzoraka zalijevanih s epoksi

masom. Na osnovu spektrofotometrijskih i denzitometrijskih mjerenja definiran je

utjecaj penetracije boje unutar tiskovnih podloga na kvalitetu otiska.

Abstract (english)

Paper production is based on a cellulose as a basic raw material. Environment

awareness and sustainable development has led to an increase in the usage of recycled

printing paper. As recycled fibers cannot provide the same level of quality for products

as paper, the usage of alternative fiber resources is of great importance.

This paper analyses the influence of the depth of dye penetration inside the imprinted

laboratory printing media obtained from recycled wood fibers and non-wood fibers on

the quality of the print. The research is done on the laboratory printing paper that were

made by mixing non-wood fibers (wheat, barley and triticale) with recycled wood fibers

in different ratios. Samples were printed with the digital UV ink jet printing technique.

The analysis of the depth of ink penetration within the printing papers was observed on

images using an image analysis program. Images were obtained with a light microscope

by observing the cross-section of epoxy-massed samples. The influence of ink

penetration inside the printing paper on the print quality was defined based on

spectrophotometric and densitometric measurements.
