I concur - try Red River papers.? I've had excellent results with them.
I might add that I was a fan of 100% carbon pigments on Arches (uncoated) watercolor paper.? I suspect nothing will last longer.
But my gallery customers couldn't care less.? They buy the image, not the technology and multi-century longevity.? Good, modern pigments on a satin paper will last long enough.? (Do not use dyes!? They definitely fade.)
So, now, a 44" roll of Red River satin paper stays in my large printer.? I spray the?images with 4 coats of Print Shield (acrylic spray), dry mount them on acid-free foam core, frame them with frames I cut from 9' lengths, and display them without glazing.? I've had no reports of any damage or other negative issues.
