Paul, I'm not trying to come off as consistantly argumentative. I'm
just interested in every aspect of these issues 
presented, particularly on this list.
To my knowledge, MIS full quad inksets have not been tested by RIT.
Let's assume for a moment that the lighter inks are 
dilutions of the black (is it the same black that was tested?). As
Wilhelm pointed out to the chagrin of many ink makers, 
diluting ink for light colors resulted in significanly shorter life.
This became an issue for Generations regarding how their M 
light and C light inks were made. So the RIT results really may have
nothing to do with how long an MIS quad print will last, 
and different coatings, which are evolving, can make a difference of
decades (i.e. Liege vrs Royal Plush).
Equally useful :), we get occassional reports from the Piezography
people about their window tests. Wilhelm has proven 
less than reliable too. All of these tests, yours, anyones, when
acumulated are of value. But I don't see how anyone can 
make any definitive statements, some of them could be dead wrong
because of methodology.
Lysonic dye inks, both color and quadtone, have recieved fantastic
Wilhelm years on some papers. So we can't even 
conclude that the presence of dyes will shorten print life
conclusively. K vrs CMY blends from the same inkset show that 
mixing colors creates yet another possible problem.
As for warming being the biggest problem, this is restated for people
new to the issue. We are all printing on coated 
papers, so we get warming. Any lurkers here printing on uncoated
papers like Somerset Velvet know what these inksets 
really look like. Our prints are warming as the ink and coating
complete their chemical interaction. Is the ink warming? Is 
the coating warming? Both? These inks do not warm in and of
themselves, but when they hit that coating...
The warming is a fact of life. Until a new coating, or some very
different inkset comes along, it's part of the deal. I've been  
making some Piezo ink prints on a gelatin coated paper the last few
weeks, they are not warming at all.
I don't "like to warm" my prints. But I don't want the print to warm
on someone's wall after they bought it. So the prints that 
go in my portfolio are brought to the point they will closely
resemble (hopefully) for quite some time.
It would be great if the prints stayed the way they emerge from the
printer. But even you are suggesting an 
overcompensation so they will settle to where you want them.
So... more stuff to confuse the issue.
