That'll do it. Of course, you don't need the whole wedge just to find the
Dmax. But it's worth knowing if the paper/ink/driver combo clips at the low
end--often, you find the last few patches are nailed to black. I suppose
it's even possible that 100% will be less dense than 95%, because of the way
the driver mixes colors with the black.

What is the procedure for measuring reflection density using a Spectrocam.
