Couldn't agree more.
The whole point of FWA / OBE is either to make cheap paper not look so cheap,
or similar to the "loudness wars" of music industry editing to stand out from
everything else on the shelf.
If the goal is colorimetric accuracy, you only want fluorescent agents in the
end result if they were present in the original scene -- a challenge everybody
instantly recognizes is way beyond typical printing environments. Short of
silkscreens and art presses, who's printing with fluorescent inks? And then you
ideally need a viewing environment where the UV spectrum is similarly
And if the goal is more "punch," that right there tells you you're not looking
for colorimetric accuracy. You want to turn the knobs all the way to 11.
Or: the instant you load your printer with fluorescent paper, you should
automatically relax all your color tolerances in proportion to the amount of
FWA in the paper. If you're using Hahnemuhle or the like, you can somewhat
pretend it's OBA free and enjoy a bit of "punch." If it's office copy
paper...you're trying to dial in the last bit of perfection...why, exactly?
This "measure with a micrometer, mark with chalk, cut with an axe" mentality is
all throughout the printing business. National Geographic is famous for print
quality right? Yet fully 0.1% of their readership (at best) is reading it in a
controlled environment. Most are reading it in the evenings in living rooms
with who-knows-what sorts of lights...many of which are quite dim. As a result,
the photos in the magazine almost always are much too dark for the viewing
conditions -- and never mind the odd color from the cheap fluorescent spirals.
There are certainly those who absolutely need 1 DE reproduction abilities. But
damned few -- and they know better than to use FWA-laced paper in the first
