I hear these two are some of the better aftermarket ink suppliers out there, but I'm curious as to their longevity.
Are you talking about dye or pigment based inks, and for what printer?
Also, some searching has me come across nanodigitalink-- they claim a BWS lightfastness scale of 5-6 (~20-50 years under glass) which to me is acceptable -- I just hope I won't be disappointed!
OCP isn't an 'aftermarket' ink manufacturer...it is an established German company producing ink for the print industry and then for the inkjet re-manufacturing market.
Google their company plant in Germany. You will see what inks are available for what printers with all the technical specs.
