	Barrier Polymeric Layers for Inkjet Prints Protection Štěpánková, Eva ; Čeppan, Michal (oponent) ; Ďurovič, Michal (oponent) ; Veselý, Michal (vedoucí práce) This paper gives a brief overview on the published and accepted standards and methods for colour photography and print lightfastness measuring and evaluating. A comparison of selected valid standards and evaluation suggestions has been made. The aim of this work was to protect inkjet prints by varnishing. Varnish compatible with photographic media was prepared. Composition was enriched by EVERSORB UV absorber addition in two concentrations. For comparison also three commercial varnishes were also used. Prints made with three types of dye-based ink sets proofed with varnish layer were exposed to accelerated lightfastness test in xenon test chamber as well as to accelerated gasfading test in ozone test chamber. Print gamut volume was calculated using measured reflectance spectra and VolGa software. The change in gamut volume during ozone and light induced ageing was monitored until the endpoint criterion was reached or test ended. Test endpoint was set to be 30% of gamut volume loss. A reciprocity law failure was observed, which indicates a lower credibility of long lifetime predictions. Gamut volume change was used to judge the effectiveness of UV and ozone protection provided by prepared composition. Gas transmission rate by carrier gas method and transmission of water vapour trough the studied varnish layers applied on calendered paper was determined. Úplný záznam
