I agree with Javier, since your paper does not face to the white light
source, it could be suitable to ensure your paper is not going to be
exposed even when that white light is mixed with the safety darkroom
safety red/orange light. It's quite difficult to get a whole room in
dark because of windows and doors, this is not essential for paper as it
is for negative film.

So I'm wondering if the place I have in mind for it is dark enough.

It's the bottom half of my live/work space which has no windows, at
the opposite end of the room which opens into the upstairs. I sat down
there for a while tonight to see how dark it was; after a few minutes,
I could just barely make out faint lightness at the other end of the
room, but could see nothing definite.

So I'm wondering if there's a rule of thumb about how dark is dark
enough. You know, something like the "sunny 16" rule about what can be
seen with the naked eye.

Yeah, yeah, I know I could make some test exposures with paper, but
you know what? I just don't want to. I'm not planning on making any
gallery-quality prints, just want to print the last couple of rolls of
film that I shot. So if you have any rough guidelines, I'm all ears.

My impression is that it's plenty dark enough, so long as I work
fairly efficiently and don't leave paper exposed to ambient light for
too long.


I think it will be perfectly fine. In my (no so) darkroom I can see lots
of light under the door, and as far as the paper does not "see" it (I
don't know how express it, I just keep the sensible face of the paper
upwards: the light comes in from the floor) I never have had a problem.
Yes, I have made test exposures, no fogging.
