The HP Vivera inks on quality FA papers have astonishing longevity just pinned to the wall. So, if longevity was no longer a factor would you prefer to see the texture of the paper and have a more direct experience with the print? Or would you prefer the interference of glass when it is really just a holdover from old technology? Maybe it's time to change the standard, at least for the state of the art in ink/paper technology.
