I tried this UT2 & Eboni (or maybe no) black printing with Epson Premium Glossy and Epson Glossy Photo Paper. The dmax is lower than with Ilford or Photo K, but still very good. Premium Glossy hits 2.18, and cheap Glossy Photo paper hits 1.91. While the Glossy Photo Paper sounds low compared to other RC dmax numbers we've been throwing around lately, it looks absolutely black. I don't think anyone would see any difference between this and the best. I think part of it is that the black is cold. I've noticed, for example, that the relatively cooler Eboni looks darker than the warmer Epson UC Matte black, even though my densitometer says the Epson matte black is a bit darker. All of the above seem to give the best dmax with the sepia toner pulled out completely. I'm not sure how much if any Eboni the printer is putting in the mix. The darkness of the UT2 cold ink is probably a major part of why this is working so well. I must say that with UT2 and when curves are used, I think we now have a system that will print great on matte or glossy without changing the black ink.

There is a cross-over in the sepia print, but it is so far into the black that I can't see it. Specifically, the 90% patch is 14 units warm, the 95% is 4 units warm, and the 100% (at 2.29) is 9 units cool.

OK, this is a little half-baked, but the bottom line is that I've hit a dmax of 2.28 on Ilford Galerie Smooth Pearl - with Eboni. There is not significant dusting or rub-off. The secret is that the UT2 (and perhaps UT1) inks use a base that is the glossy binder. It's not an acrylic coating on the particle. So, I don't let Eboni sit there by itself - or barely at all. So, to the extent there is Eboni there, it is held by the base that carried the other inks into that spot. The best dmax so far is with the yellow position sepia toner pulled out entirely at the 100% spot. Whether I can write full curves for this is untested. So, there is more to do here before declaring any kind of victory, but we may not need to mess with switching blacks any more. Now that would be nice.
