Low pressure, a #1 tip and needle and skill in the hands of the person holding the airbrush is all that is needed.
Drop the pressure down to 10 lbs or so, thin the paint to the consistancy of mik, strain the paint through a piece of women's nylons and practice, practice, practice.

“Wisdom is the right use of knowledge. To know is not
to be wise. Many men know a great deal, and are all the greater fools
for it. There is no fool so great a fool as a knowing fool. But to know
how to use knowledge is to have wisdom. " Charles Spurgeon
