Fuzzy fonts because Ghostscript too old
So you’ve done everything the FAQ has told you that you need,
correct fonts properly installed and appearing in the dvips
output, but still you get fuzzy character output after
distilling with ghostscript.
The problem could arise from too old a version of
ghostscript, which you may be using directly, or via a
script such as ps2pdf (distributed with
ghostscript itself), dvipdf, or similar.
Though ghostscript was capable of distillation from
version 5.50, that version could only produce bitmap Type 3 output of
any font other than the fundamental 35 fonts (Times,
Helvetica, etc.). Later versions added ‘complete’
distillation, but it wasn’t until version 6.50 that one could rely on
it for everyday work.
So, if your PDF output still looks fuzzy in Acrobat
Reader, upgrade ghostscript. The new version
should be at least version 6.50, of course, but it’s usually good
policy to go to the most recent version (version 8.12 at the time of
writing — 2003).
