Close to Claria

There is not a wise word to say about third party inks if the prints made with them did not go through the same severe testing that Aardenburg-Imaging or Wilhelm-Research do. Media choices matter too for the test results. Third party supplier ads and documents are not interesting if they do not refer to test results like that.

That said and "Close to Claria" in mind, there is strong evidence that Claria is roughly the same "dye" ink as used in Epson, FujiFilm, Noritsu dry minilabs. Big carts and by that a much lower price per ML. You could refill from carts like that. Papers meant for the same minilabs are priced at $ 0.55 per square foot for the heaviest papers but they go in larger quantities. I think you can find Wilhelm tests of the dry minilab prints. Possible source of the inks are FujiFilm dyes but that is more speculative:
