Abstract:

The aim of this bachelor thesis was to evaluate and compare lightfastness of offset and inkjet inks. Lightfastness was tested by using accelerated and non-accelerated aging. For inkjet printing pigment-based T6052 (cyan), T6053 (magenta), T6054 (yellow), T6651 (black), T6055 (light cyan), T6056 (light magenta) and T6057 (light black) inks were used by pigment-based printer Epson Stylus Pro 4880 and dye-based T6642 (cyan), T6643 (magenta), T6644 (yellow) and T6641 (black) inks were used by dye-based printer Epson L110. Microporous photo gloss paper Foma FP 2110 with grammage of 210 g/m2 was used as a substrate. For offset printing the inks from Bestack Process series from company T&K Toka were used. Offset paper with grammage of 80 g/m2 was used as a substrate. Several sets of samples were examined. First set of every type of ink was evaluated in interior during december?june, second during march?june and the third one was irradiated in chamber for accelerated aging Q-Sun Xe-1B. For evaluation of color changes, a color difference ÄE was measured every week.
