Predavanje "Study of inkjet prints fading proces"

Pozvani ste na predavanje “Study of inkjet prints fading proces”, koje će održati Izv.prof. Michal Vesely dr.sc. sa sveučilišta Brno University of Technology, Faculty of Chemistry, Czech Republic u okviru Erasmus Staff  Traininga.

Predavanje će se održati u srijedu 16. studenog 2011. godine u 10 sati u dvorani A na Sveučilištu u Zagrebu, Grafički fakultet (Getaldićeva 2).

Kratki sadržaj predavanja:

Special test charts were printed on two types of inkjet papers by dye-based inks and exposed to ozone-enriched environment and UV radiation. The colorimetric values L*a*b* and colour gamut volume were calculated from spectral data of all patches of the test charts. The ozone effect on the prints was evaluated in the terms of total colour difference. Results of accelerated ageing by UV radiation of printed samples and samples influenced by the ozone were evaluated in the same way. It was found out that UV radiation and ozone treatment have a different effect on the degradation of dyes. The degradation rate is also strongly influenced by the receiving layer composition of papers used for inkjet printing.
