[Alt-photo] Cone Color inks and Carts

[Don]

Hello Folks,

I've been considering switching to Cone Color inks and refillable cartridges
for my Epson 3800 to reduce consumable costs for producing digital
negatives.

I'm curious to learn if anyone has used the Cone Color inks and if they can
produce acceptable negative densities for printing alternative process
prints.

So can anyone report thumbs up or down for this product?

Thanks,

Don Bryant
