Andre,

Thanks for the interesting link. I did some inkjet coating trials in the
spring of 2001 using ClearSheild, the Golden MSA products and other
material. It is interesting to see someone doing some fade testing with
these coatings. I didn't pursue it myself since I didn't quite like the look
of the coated prints and flaws in the coating such as dust, streaks and
bubbles were a problem.

I pulled out my samples from 2 years ago that have been in dark storage and
I want to point out that the ClearSheild coatings have yellowed just
slightly. So while there is an incredible gain in Dmax there is a loss in
paper brightness and an overall warming effect.

The comparisons of the test data on the livick site are certainly valid but
I would not take the display life numbers seriously. There are just too many
variables to draw those kind of conclusions. It should also be noted that
most of us would find 250 Lux much too dim a light for viewing prints. As an
example a 100W light bulb is in the 1000 to 1250 lux range.

Lots of good coating application data on the site.

One thing of great importance in his tests is the failure of the uncoated
UltraChrome inks. People using the full UltraChrome color set to make B&W
prints should perhaps take note of this. If you are concerned about making
archival prints or prints that maintain their neutral hue, this may not be
the best ink set to go with.
