If I remember correctly, HP produces pigment based color inks for their more serious inkjet lines, and these systems generally use 4 or more cartridges.
However, even though I balk at my 4515 for having dye based color inks, their fade resistance is astonishing.
HP always uses pigment based black inks on every inkjet, so text is always at archival quality on good paper.
I still like the tank so I upgraded to an ET-8550 which uses mainly dye-based inks except for a pigment black. Photos and art reproductions I print from that still look OK 2.5 years later of being on display, even in a south-facing room in my house which seems to be a good "accelerated aging" environment. Epson makes an Pro ET line which uses pigment-based ink, but when I tried to get one during the pandemic I couldn't find one so I got the ET-8550.
