Digital BW, The Print

The MIS dye is not the Claria/Noritsu dye that I recommend.  Old style dyes
fade very quckly.

Even the Claria/Noritsu dyes fade faster than a good carbon-based inkset.
 A post-printing spray that seals the Claria/Noritsu dyes is necessary to
bring even the advanced dyes up into the range of Epson UC color prints in
terms of fading.

See the fade test results at  http://www.aardenburg-imaging.com/   If you
click on the top of the Conservation Display Rating, that puts the results
in order by that column.  Then you can see at a quick glance how the
various Claria tests do compared to other ink-paper combination.  The Print
Shield Spray makes a huge difference.  But, again, this is Claria -- which
I suspect is way different than MIS dyes.  Some of the relevant testing is
summarized in this screen grab, including Wilhelm's --

I don't recommend any dyes for long term, fine art type display.  However,
the Claria on Canson, sprayed with Print Shield, did surprisingly well in
the Aardenburg-Imaging test.  I have used un-sprayed Claria for cards,
printed on the Red River metallic paper, that have been displayed for a
year without any fade or color change that is apparent in casual viewing.
 (I have not done a comparison to a dark storage card.)
