Hello Joel,

Thanks for the reply.

My post is more in relation to inkjet permanence data from standard
tests procedure than about choosing which inkset and paper combination
which give the most in term of display permanence.

What H. Wilhelm is doing is much like the Miles Per Gallon rating of
the automobile industry. While it cannot determine what mpg you'll get
out of your car, it allows for a comparisation between car models.

What W.I.R. is bringing to the table is data: light stability data and
permanence data. It gives a ballpark figure on what should be expected
in term of display permanence when a certain combination of ink and
paper is used. But data nonetheless, and data that I can print and
show art fair jurors, art gallery owners and prospective clients.

As far as MIS inkset's are concerned I have nothing, save for what
Paul Roark has published and I'll see what it is on his website.

I do not hold W.I.R.'s test to face value: just change one or two
variable like humidity or heat or both and display permanence rapidly
diminishes.

As far as doing the test myself, I'd rather leave that to others. I
remember Jone Cone doing the south window permanence test a few years
ag and also the late Jerry Olson putting prints by the rear window of
his car. While not scientific, a lot was learned from these tests and
from your own test also.

But, when I'm asked to provide info on print permanence, I'd rather
have some printed data that people can look at, rather than having to
say "Well, I know this guy who..."

Cheers,
Andre Moreau
