### Quality of PDF from PostScript

Any reasonable PostScript, including any output of dvips, may be converted to PDF, using (for example) a sufficiently recent version of ghostscript, Frank Siegert's (shareware) PStill, or Adobe's (commercial) Distiller.

But, although the job may (almost always) be done, the results are often not acceptable: the most frequent problem is bad presentation of the character glyphs that make up the document. The following answers offer solutions to this (and other) problems of bad presentation. Issues covered are:

- Wrong type of fonts used, which is the commonest cause of fuzzy text.
- ghostscript too old, which can also result in fuzzy text.
- Switching to font encoding T1, which is yet another possible cause of fuzzy text.
- Another problem - missing characters - arises from an aged version of Adobe Distiller.
- Finally, there's the common confusion that arises from using the dvips configuration file `-Ppdf`, the weird characters.

It should be noted that Adobe Reader 6 (released in mid-2003) does not exhibit the "fuzziness" that so many of the answers below address. This is of course good news: however, it will inevitably be a long time before every user in the world has this (or later) versions, so the remedies below are going to remain for some time to come.
