Prints fading

HP Recommended
DesignJet T795

I have printed over a hundred posters up to 85"x27" for indoor display. I am using the HP Designjet795 with Designjet 72 ink cartridges and the HP Insta-dry Gloss Photo Paper (Q6576A). Though they recieve indirect fluorescent ligt and little natural light with moderate hunidity they are fading QUICKLY. No problem for 7 months then rapid fading over the last month. I need to identify and resolve the cause before going through the time and expense of reprinting. So far everyone has said "That shouldn't happen". I have been advised to try a matte finish paper, but I still need to know the cause of the fading to prevent it going forward. Any aid would be appreciated.

Inkjet prints generally fade due to light exposure. Although HP says prints will last for years without fading, this is only true when the print is stored under high grade protective glass. Prints consistantly exposed to direct light, even if its not sunlight, will fade. UV exposure will speed the process. Prints can also fade due to high levels of ozone in the air or react with air bourne chemicals.  Laminating posters should improve there lifespan. Using a Premium HP paper should help as well. But essentially you need to find what in your enviroment has changed and caused this to occur.
