Tom Trotter,
Thanks for the link. I will read it when I get a bit more time.
I did a good bit of reading on print permanance about 1.5 years ago. It is
interesting that Hewlett Packard products are featured on this page. I
recall reading from an independant party a scathing indightment of the
methodology used in testing to support HP's claims.
Essentially testing consists of exposure to light of a given quality over a
period of time and evaluations and estimates are made based on the results
during the time of the test.
HP's claims were grossly beyond those made by one of their major competitors
- Epson. It turned out that the HP study utilized a light source of about
33% the intensity of the light source in the Epson test and exposure per
session consisted of a timed period of half that of Epson. In short, the
test had been constructed to give the desired results to allow them to use
(qualified) longivity claims in their marketing...
Having not (yet) read the claims made on your link and having not read
expert evaluation of those claims I cannot judge the the test.
Since you have rightly or wrongly bought into the results I ask you again -
How reliable was this study?"
Speedy
