I have a few questions about your approach for this new matte black ink from the new supplier. When you create a variable tone ink set are you actually making curve that utilize two sets of 3K dilutions, or is this a 5 dilution ink set with the sixth ink as a "toning ink"?
As for the 2MK profiles for uncoated Arches (cold/hot press?): are these two 100% matte black inks or is one a dilution to fill in the gaps and punch up the dmax? As for Dmax, that is a lot of density. However, something I have always wondered about with your profiles has been: what is happening to the spread/bleed of the dot and how to maintain detail on uncoated papers? I haven't had a chance to test it for myself, although my workload is starting to slow down and I will have more time to mess with this stuff.
I made a few prints this morning with my newly created profiles for Canson Edition Etching and they are easily some of the better prints I have made since I had to hang up the Cone Piezotone dual quads.
