Abstract

Poznato je da se vremenom otisak Ink jeta mijenja. U ovom radu istraženo je što se događa sa otiscima u kratkom vremenskom periodu. Za otiskivanje eksperimentalnih uzoraka koristili su se pisači Epson stylus PRO 7000 i Epson stylus photo R2400 koji primjenjuju DYE i pigmentirana bojila, te specifična tiskovna podloga "Offset proof paper 9200 semimatt". Maksimalno trajanje istraživanja trajalo je 144 sati, pri ćemu se istraživalo u karakterističnim vremenskim periodima od 0h, 0.07h, 0.25h, 0.5h, 1h, 4h, 24h, 48h, 72h, 144h. Mjerenje otisaka izvedeno je sa uređajem Xrite DTP – 41 i programom "Monaco platinum" sa kojim je generirana gamut reprodukcija, tj. prostorni gamuti. Prikazani kolorimetrijski rezultati su L*, a*, b* vrijednosti. Konačni rezultati prikazani su kao krivulje reprodukcije ovisne o vremenu mjerenja, s dobivenom razlikom obojenja ΔE i postotku gustoće obojenja za osnovne boje. Istraživanjem se može zaključiti kako vrijednost ΔE pada ovisno o sušenju i starenju otisaka. Također, otisak otisnut printerom Epson stylus photo R2400 puno je stabilniji, ali manje kvalitetan sa stajališta struke. Što znaći da je konstantnost važnija u odnosu na kvalitetu reprodukcije.

Abstract in english:	It is known that prints are changing by the time. In this graduation paper, research is based on what happens with prints in briefly time periode. Experimental samples were made by printers Epson stylus PRO 7000 and Epson stylus photo R2400 which are applying DYE and pigment inks, on a specified paper "Offset proof paper 9200 semimatt". Complete time of research lasted 144 hours, with characteristical time periods of 0h, 0.07h, 0.25h, 0.5h, 1h, 4h, 24h, 48h, 72h, 144h. Prints were measured with device Xrite DTP – 41 and application "Monaco platinum" which is used for generate gamut reproduction. Presented colorimetryic results are L*, a*, b* values. Final results were presented as reproduction curves, with acquired color difference ΔE and percentage of color density. With this research we could conclude that color difference ΔE decreases depending on drying and print ageing. Also, print made by printer Epson stylus photo R2400 is much stable, but less quality.
