No work at all.

Just don't resample them (shrinking / enlarging is okay) and they'll  
turn out okay.

If you desire better quality open them in PhotoShop 6 or later and  
re-save them as .eps or .pdf with the ``direct interpolation key''  
turned on.

Alternately, you can do like Michael Harvey and just re-draw them all  
in pen and ink as he did for his book _Creative Lettering Today_

requirements the printer has and either re-distill to that, or check  
the output using a pre-flight program.
