We switched to 3rd party inks BECAUSE they didn't stand behind that claim when it failed.
Yellow literally disappeared in less than 18 months outdoor unlaminated on hundreds of decals placed on trash cans. A few other non-laminated short term decals as well. (all outdoors)
We laminate everything that is supposed to last...but if they didn't even make it half of the "claimed" lifespan, that's pretty pathetic. I sent samples and photos etc and still were told...too bad...they must have been exposed to other chemical agents or something. Pfffft.
What they should say is 3 years outdoors unlaminated if only in shade the whole time.
That's ok...I'm saving a buttload of money each year using Solaris Inks that look just as good and haven't done anything bad to my machine in 4 years.
That's just my experience. Roland makes Awesome machines.
Have you tested the longevity of the 3rd party inks under the same conditions? Inquiring minds want to know.
Haven't seen the dropout as fast. Several things we've done I see everyday that get full UV are only starting to fade and I still see light yellow...after 2 years.
I just wish they wouldn't be allowed to make the claim if it simply isn't true.
Unlaminated garbage can stickers? Wow ... I can just imagine the amount of crap and abuse those stickers got.
Yellow is the first color to go though. Way up here in the dark dark north. Prints still look vibrant for a good three years.
