I have a PDF from someone else that uses type 3 fonts and so is almost unreadable on screen (example: http://cseweb.ucsd.edu/~goguen/pps/tcs97.pdf ). If I run pdf2ps on it and open the PS in evince, the fonts look fine however.
Since there's evidently a way to make the document render properly, is there a way I can convert it back to PDF and preserve the good-looking fonts? ps2pdf produces output that looks just like the original input.
I have a feeling this should be such a standard task (given how often I see type-3 font PDFs) that there should be an easy way to do this. Some ghostscript options perhaps?
My system is ubuntu 12.04/precise and I can install any package or download free software that may help; I've already got a full TeX, ghostscript and pdftk installation if that helps.
