I'm aware that modern pigment inks retain their colour and tonality a lot longer than dye based inks. However right now I don't have a pigment based printer. What I was wondering is if anybody here has tried taking the same approach to your dye based inks that artists/painters take to their paintings and spray an anti UV and water repellent solution over top your work? I'm interested to know if there are any caveats (e.g. need to bump exposure in print to offset a darkening from a spray ). Has anybody tried anything like this? Thanks, Tom.
