pdflatex font embedding

So, publishing papers sometimes involves using IEEE’s PDF eXpress.

Today I found that pdflatex is not embedding the font required for the publishing process.

This seems to be a working solution:

First convert your PDF file to Postscript:

pdftops main.pdf main.ps

Then, reconvert the PDF back and enforce font embedding:

ps2pdf14 -dPDFSETTINGS=/prepress -dEmbedAllFonts=true main.ps main2.pdf

To see if the fonts that you need are embedded, run

pdffonts main.pdf
