<h2 id="embedding-fonts-in-pdfs">Embedding fonts in PDFs</h2>
<p>To check whether fonts are embedded, use <code>pdffonts</code>, which is included with <code>xpdf</code>. <code>pdffonts</code> gives output that looks like this:</p>
<div class="codehilite"><pre><span></span>$ pdffonts paper.pdf
name                                 type         emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
FHQIOS+NimbusRomNo9L-Medi            Type 1       yes yes no       6  0
NEESMN+NimbusRomNo9L-Regu            Type 1       yes yes no       9  0
PJQNOS+CMSY10                        Type 1       yes yes no      12  0
</pre></div>


<p>You want <code>emb</code> to be <code>yes</code> for all fonts (and possibly <code>sub</code> as well; also, all fonts should be Type 1, not Type 3). By default in Ubuntu, pdflatex should embed all fonts. Just in case, you can check <code>/etc/texmf/updmap.d/00updmap.cfg</code>, which should have a line like this:</p>
<p><code>pdftexDownloadBase14 true</code></p>
<p>If it&rsquo;s set to <code>false</code>, change it to <code>true</code>, then run <code>update-updmap</code> as root. Remake the PDF; if it still has non-embedded fonts, your figures are probably to blame. Check your PDF figures and make sure their fonts are embedded (using the <code>pdffonts</code> command). For anything that doesn&rsquo;t have embedded fonts, you can try the following magical invocation:</p>
<div class="codehilite"><pre><span></span>gs -dSAFER -dNOPLATFONTS -dNOPAUSE -dBATCH -sDEVICE=pdfwrite \
-sPAPERSIZE=letter -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer \
-dCompatibilityLevel=1.4 -dMaxSubsetPct=100 -dSubsetFonts=true \
-dEmbedAllFonts=true -sOutputFile=figures/Mprime-new.pdf -f figures/Mprime.pdf
</pre></div>


<p>This creates a file <code>figures/Mprime-new.pdf</code> that is hopefully identical to the input file <code>figures/Mprime.pdf</code>, except that the fonts are embedded. Run <code>pdffonts</code> on it to check.</p>
<p>Once all your figures are in PDF format, remake the paper again. Hopefully, all your fonts are now embedded &mdash; check again with <code>pdffonts</code>.</p>
