Got a quick question here... At the nature center where I volunteer, they are looking to print some new pics of the critters for display on the cages. Since the cages are outdoors, the problem is that every time we've tried, the pictures sun fade really quickly (usually within a month or two). The pictures are behind plastic covers, so it's not from rain or anything, just from sun fade. I don't think it's really the paper being used either...I think it's just the pigments in the ink fading in the sun (although I could obviously be wrong).
I've looked around a little on the web and haven't found anything specific yet so can anyone suggest an ink (say from Epson or HP or someone) that is UV resistant and will hold up a little longer than ordinary inkjet ink? Anyone even heard of this before? Any suggestions?
