I understand that the sepia/carbon Piezography ink set is the most permanent of the Piezography ink sets from inkjet.mall. And the Eboni-6 ink set from inksupply.com is also very permanent.
1. In terms of permanence how do the Epson UC and K3 inksets compare to the Piezography non sepia/carbon ink sets (selenium, warm neutral, etc.) when using QTR to make monochrome prints?
2. Piezography with sepia/carbon ink set seems much more popular than Eboni-6. Is this because the results are superior, or is it because Piezography is more of a plug and play system with the supplied K7 QTR profiles?
3. Could the Eboni-6 pigments, which cost a lot less than Piezography K7, be diluted to work with the K7 profiles supplied with QTR?
Thanks in advance for any comments.
