Thank you Paul.

In a search to see what is available in Europe in warm carbon inks I cut 
an empty Epson 3880 LLK cart open (could not pull ink out with a 
syringe) and got 15 ML from the opened ink pouch. On a near neutral 
glossy paper (Epson Proofing White SemiMatte) the brushed on LLK had a 
more yellow base than being warm compared to the diluted MIS Eboni and 
HP MK brush strokes next to it.
The LLK and I guess the Epson PK diluted used straight is not creating a 
nice ink color in my opinion. Is that your observation too?

The Eboni ink I still had is 5 years old so may not be representing 
today's Eboni but I noticed that there is little difference with the HP 
MK visually, from tungsten light to daylight. The HP measured slightly 
warmer (here and  in Aardenburg measurements) but I do not see that 
difference to Eboni. I will stick to HP MK for MK plain.

On your lament on blending ICCs:

You can not blend ICC (B&W) printer profiles in Qimage but at least give 
several nested images on one print page different printer profiles 
(and/or different rendering choices).

With the Kodak Custom Color Tools in XP + PS2  it should be possible to 
create blended ICC profiles I think. Might not work with the embedded 
curves though. Say 1 or 3 steps in between warm and neutral. KCCT is not 
installed anymore here but I could do that. Still not a continuous 
blending range like possible with QTR.
