The inks all seem to warm up.  However, some warm more that others.  And
some papers are better than others.

EAM, while cheap, is among the best papers in my fade and warming tests with
pigmented inks.

The MIS blacks are not all the same.  With respect to warming, fading and
depth of black, the MIS FS and VM blacks are the best.  They are the same.
Double density and archival (as in the MIS color inkset) blacks are
different and do not do as well on my tests.  But they are fine inks.

Generations enhanced K warms substantially more and faster, being about 25%
dye.

Try the FS-N inkset.  It should warm noticeably less.

They do warm.  Like I said, try the FS-N.  The reduction in warming is
significant.

I agree.  The only papers I've tested that has better blacks are the
Hahnemuhle papers.  They may have faster dark tone fading, however, so I'm
not sure which would be better after extended display.

I'm fade testing some FS-N on EAM with Lyson Print Guard.  We'll see how
that affects the fading and warming.  I expect it will help.  However, the
blacks with the Print Guard spray were weaker than the un-sprayed print.

Paul,

Thanks for the reply. I just ordered some Generations black cuz someone said
it didn't turn as brown!  The print that turned brown could have been a
fluke - Im doing more tests. My web page shot of it is quite true to life.
I like the EAM papers for my work because of the smooth finish and as far as
I'm concered the blacks are fine for most images. I print relatively small.  
The way I see it the increased range of low values available more than makes
up for any loss of blackness at the zero end.  It just keeps going and going. 

  BTW I fooled around with doing double hit blacks by shoving Threshold as
far west as needed and printing that under the main image. A varnish coat -
if ever available - would work the same way.
