However, my understanding is that they are the carbon tone after all dyes, etc. are gone -- like the old MIS quad or PiezoBW after totally warming. I mixed an inkset based on the Epson UltraChrome matte black that had that degree of warmth. At first I really liked it, but in addition to some printing problems, when I took sample prints to the gallery where I hang in a mixed media context, I found the tone was not warm enough. The prints still looked like just B&W prints, and the color paintings made them look drab. What I've found -- and a major reason I use sepia -- is that the sepia tone seems to do much better in competition with and showing next to color images. The neutral B&W looks very drab in those situations, but the sepia tone seems to give the eye/brain enough color to avoid that drab feeling. The carbon warm tone is not enough for this purpose. The vm-sepia does the job very well, however.

I don't use the strongest sepia curve because I find it is actually too strong. I prefer what I call a "light sepia." The standard vm-cool curves produces this look. > The other advantage of the sepia piezotones is that > they are much more > stable to fade and warm shift...being made from 100% > pigment, unlike the VM sets. The Cone sepia tone, no doubt, is more stable. The VM-S grays are the FS-N inks. As such, the neutral gray does not warm on EEM/EAM. The FS inks do fade faster than the newest 100% pigment inksets, however. A year ago I would have said the FS inkset was 100% pigment. It, and the FS-N, are basically dilutions of the FS/VM-K, which is essentially the same as the PiezoBW K. I recall being told that the PiezoBW-K was carbon that was "coated" with a colorant. So, I assumed that description was accurate for the FS/VM-K also. Moreover, the PiezoBW-K and FS/VM-K performed better than any black I'd tested except the Epson Archival black (and now also the UltraChrome blacks). So, the FS/VM/PiezoBW black inks were and are very good -- so much better than the other inks that were said to have some dyes in them, that, consistent with the descriptions I'd heard, I concluded the ink must indeed be pigment only. I now think the reality is that the FS/VM/PiezoBW blacks do have some dye in them, but due to the co-solvent base, the dyes tend to "aggregate" (clump up) -- probably around the carbon pigments. So, while the carbon may not be coated like the Epson Archival resin coating, the dye is probably not just a thin coating on the paper. As such, the pigment/dye masses have a surface area to volume ratio that is closer to a pure pigment than would be the case with a black pigmented ink that has some dye in it but does not have the co-solvent base. The reason the FS midtones fade faster than the black is probably that the black is diluted with a standard, non-co-solvent base that dilutes the co-solvent and destroys the "aggregating" function of the co-solvent. As such, what little dye is in there burns off relatively rapidly. However, these are still very respectable inkset, and I have not seen any disturbing warming or fading in the FS-N or vm-s prints that I have. In fact, I still have old MIS quad prints on my walls -- fully warmed but looking fine. One must remember that after the small percentage of dyes burns off these older pigmented inksets, they become "100% pigment." That said, I do plan on updating the vm-s with a tougher set of pigments, and probably ones that will print on glossy papers. Don't expect anything for 6 months, however. Paul http://www.PaulRoark.com
