Abstract

Svijet se susreće sa sve manjom količinom šuma, odnosno drveća kao glavne sirovine

za celulozna vlakanaca, stoga je proizvodnja papira usredotočena na nove izvore

sirovina. Svijest o održivom razvoju i ekologiji nameće upotrebu alternativnih izvora

celulozna vlakanca za proizvodnju papira iz poljoprivrednih ostataka kao što su slama

pšenice, ječma i pšenoraži. U ovom radu analizirana je uporabljivost laboratorijskih

tiskovnih podloga dobivenih s alternativnim ne drvnih vlakanaca. Laboratorijske

tiskovne podloge izrađene su miješanjem ne drvnih vlakanaca (slame pšenice, ječma

i pšenoraži) s recikliranim drvnim vlakancima u jednakim masenim omjerima od 30%.

Uzorci su potom otisnuti s bakrotiskarskom tehnikom tiska kao najkvalitetnijom

tehnikom u području tiska ambalaže. Usporedba uporabljivosti laboratorijskih tiskovnih

podloga s ne drvnih vlakanaca rađena je na otiscima dobivenim pomoću

konvencionalnih boja i UV boja. Analiza uporabljivost izvedena je na osnovu parametra

neravnomjerne pokrivenosti laboratorijskih tiskovnih podloga s boje na otiscima

dobivenim bakrotiskarskom tehnikom tiska. Vrijednosti neravnomjerne pokrivenosti

laboratorijskih tiskovnih podloga s bojom na otiscima dobivenih s procesnim bojama

određivane su pomoću programa za slikovnu analizu ImageJ te su grafički prikazane.

Abstract (english)

The world is facing a decline in forests, i.e. trees as the main raw material for cellulose

fibers, which is why paper manufacturing is focusing on new sources of raw materials.

The awareness of sustainable development and ecology requires the use of alternative

sources of cellulose fibers to produce paper from agricultural residues such as wheat

straw, barley and wheat straw. In this paper, the usability of laboratory printing

substrates obtained with alternative non-wood fibers was analyzed. The laboratory

printing substrates are prepared by mixing non-wood fibers (wheat straw, barley, and

ryegrass) with recycled wood fibers at a weight ratio of 30%. The samples were then

printed with the gravure printing technique as the highest quality technique in the field

of packaging printing. A comparison of the usability of laboratory printing substrates

with non-wood fibers was made on prints obtained using conventional inks and UV

inks. The analysis of usability was carried out on the basis of the parameter of

nonuniform coverage of laboratory printing substrates with ink on prints made with the

gravure printing technique. The values of non-uniform coverage of laboratory printing

substrates with ink on prints made with process inks were determined using the ImageJ

image analysis program ImageJ and are shown graphically.
