An old trick that has worked well for me is to print a B&W ramp on
glossy paper to which the ink will mainly sit on the surface rather than
be absorbed. Once it has dried one can take a small pointed brush dipped
in a bit of water or saliva if you prefer and remove a bit of ink from
the ramp that matched the area you need to spot and then spot the print
with it much as you would use a dilution of Spotone. Since it is the
same ink used for the print the match will be good and the permanence
identical.  I've used this method since the mid nineties, cheap and
effective.
