What do you mean by the EPS file being "fuzzy"? Is it just the
additional labelling which is fuzzy (in which case it may have
something to do with fonts), or is it the whole thing?

In the latter case there must be something wrong with the PS->EPS
conversion. Basically, the PostScript content of an EPS file should
be identical to that of the PS file it is derived from (you really
only need to add one "commment" to a PS file to get an EPS file,
and this should have no effect whatever on the process of rendering
the PS content -- apart from location and scale changes which
importing software may wrap it in, which would not apply to viewing
the EPS file itself in Ghostview or Ghostscript).

I'm guessing -- but if somewhere along the PS->EPS line there's
a conversion to bitmap graphics then you could get "fuzzy" output.

Another possibility is that the EPS file is really an "EPSI" file,
(Encapsulated PostScript Interchange) which includes several lines
of "Preview comment" which encode a bitmap of the PS image. This,
being bitmap, would certainly look nasty. However, again this
should not be a problem with Ghostview or Ghostscript (certainly
not with Ghostscript which should completely ignore any "comment"
and display the true PostScript directly).

Hoping this helps,
Ted.
