Bold greek letters are in the cmmbi10 font.

If you are using LaTeX, look on page 53 of the manual.  
You need to use \mbox and $...$ in ADDITION to \boldmath:

	\mbox{\boldmath $\sigma$} 

For some reason many people have gotten into the habit if overprinting using
\kern.  This is neither necessary nor desireable.  In fact, it looks pretty
bad if your output should ever go to a device with reasonable resolution...
