As long as the gamut is good I can make the needed adjustments through device profiling; most users tend to use the machine's color settings which would be an issue, but since I brew my own, the exact match is not important.

This is the crux of the issue: HP will not sell the cartridges alone (only wiht the bulk ink supply and service station, making for an expensive combination) and you are claiming tht you are using refilled HP carts, so this means they are second hand. Well, I can't keep brand new HP carts running long enough to ue up a single batch of their bulk ink, let alone run overtime to use a second batch of third party ink. I have to assume you are reclaiming HP carts using something like Lyson's Dead Head cleaning solution, which I can do myself, if it comes to that. So at that point I would simply be buying bulk ink by the bottle from Staedtler... when what I was really looking for was a source of *new* HP carts, without the bulk ink included, which HP refuses to sell, specificly to make life difficult for outfits like Staedtler. By the way: HP can indeed void the users warranty for using third party ink, even with their own carts... if they can prove it was the ink that caused the damage. > >If you need more info check out the web site www.staedtler.com. I did, but I could only find the ink section in German, which left me a bit short on info... You did not address my original issue of short term fading, though I did see pigment inks on the list; I wonder if they are less clog-prone than HPs pigment inks? What I would love to see is an encapsulated pigment ink, similar to Epson's latest, in bulk for these HP printers. That would minimize the clogging issue by keeping the pigment in suspension, while improving adhesion and gamut. C.
