thanks for the link. it was helpful.
ok so the Epson claim...
IS 1.5 years un-laminated and that all depends on "actual display environment" I'm sure they are being conservative.
NOT "less than a year" as people have "heard"
We had a Seiko 64s eco-solvent and most un-laminated prints do not fair well in Florida sun more than 1.5 years anyways.
We had one guy insist on getting a 4 x 2 decals on the sides of his van and we offered lamination but he passed. 3 months later he came back with "the face" It looks like they used some degreaser or wheel cleaner - something harsh to clean the vehicle and you could see swirls from the cleaning towels. This was printed with the stinky Seiko 64s eco-solvent.
Another good example and I should photograph it. A restaurant purchased (2) 4x8 signs and they also cut the corner on the lamination - 2 years later the sign facing the sun all day is faded but the one that only gets half a day of sun still looks new.
Thanks for the datasheet. i hate seeing run away rumors about ink fading in less than a year.
So what's up with these guys claim?

They're saying it could last 126 years if it's framed under glass.
un-laminated and outdoors? yes it can happen. of course.
and this applies to almost all solvent prints.
get some acid rain on it and your done.
I always always recommend clients to laminate anything they expect to last more than 6 months. A pigeon can fly by and crap on 2 day old un-laminated print and they get ruined.
do the up-sell and offer lamination on everything. i will keep an eye on these prints in the sun and if anything jives I will post it here.
