Ghostscript makes embedded fonts in pdf bad (all jaggy)

Ghostscript does not create embedded fonts in pdf correctly. for example http://vegro.nl/cmsfiles/ConsumentenAssortiment/Brochure/10.axd The logo symbols on the upper right ("Thermrad") are all jagged. If I open the file in Adobe Reader, there will be no problems!

Do you have this problem too? Is there a solution? I searched for a few days but can’t find anything.

I tried Ghostscript 8.64 and 8.71 on both Windows Vista and CentOS.

Thank you very much! Dave

My advice is to use Ghostscript 8.71. Then use this command line:

  gswin32c.exe ^
      -sDEVICE=pdfwrite ^
      -o thermrad-out.pdf ^
      -dPDFSETTINGS=/printer ^
      10.axd

PDF , . .axd . ( pdffonts.exe XPDF ). . 3 10.axd:

 for /l %i in (1,1,16) do (
       echo.   ............ Page %i ............................... ^
       & pdffonts.exe -f %i -l %i 10.axd ^
       & echo.)
