Digital BW, The Print

Can't speak to the RIP, but gray gamma definitely matters. Images will look
significantly darker in gamma 2.2, which obviously affects your levels,
curves, etc. decisions. I learned the hard way when I was testing my web
site and found its photos looked great on Macs...and way too dark on PC
monitors. Not sure where the old adage that you use 1.8 on Macs came from,
but I now routinely ignore it, as it mainly seems to reduce compatibility in
our PC-dominated world.
