Those are beautiful prints!
If you are hedging on the 7900 side I suggest giving us a call and getting a set of our universal 700mL carts and a set of chips with your ink. These carts are compatible with the SC-P printers so if you needed to move to the SC-P series you could keep your carts/ink intact and just move them over with new chips. We don’t officially sell the 700mL cart as a single item online at the moment but if you are getting a full stack we certainly would sell you them so that your carts are future-proof.
