As the creator of the ink I can't say I'm independent. Initial demand was so strong that we sold completely out in a week. More raw materials are arriving at our facility in early January for more production. We will then have enough made to fulfill more orders.
On bare scientific levels, we are getting to a dMax of 1.82 with the new matte black ink on Hahnemuhle Photo Rag (specifically on the x900 series printers. Some dmax varies from printhead model by a few percentage points.)
It is great to be able to chat with the ink creator!
So, good, it looks like you've cought up with HP Vivera density on matt and are a bit beyond Epson HD what was great improvement for my 3880-->P800 switch.
Number of questions comes to my mind:
1) What level of neutrality (and its homegenity through shades scale) are you able to achieve with Pro setup compared to K7?
2) As for discussion about 7>4>3, I still wonder, as written in my initial post in this thread, what is split of quality reason between the new ink and QTR software? I print a lot with QTR and Epson K3 and it gives outstanding quality compared to ABW. I just wonder if it is going to be better (and in which circumstances) when switching my 3880 to Piezography (K7 or Pro).
So, what makes the show - ink or QTR?
3) Are you going to have preset curves simulating your K7 look, especially carbon and selenium?
4) Where is a difference between 8 and 10 channels setup? What gets improved - light tones?
