Ah. I undertand I still didn't completely understand.
But as I noticed the stripes on the print from the printer, who can only process
JPEG, and JPEG being 8-bits, me seeing the stripes on the screen means they will
also appear on my prints, if my thinking is correct.

I've tried that now and I feel that has indeed helped (but at the moment I am
seeing banding everywhere, so I need a time-out). I'm going to experiment some
more with that (and try OpenEXR) later.
Thanks, Joost
