To check whether fonts are embedded, use pdffonts
, which is included with xpdf
. pdffonts
gives output that looks like this:
$ 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
You want emb
to be yes
for all fonts (and possibly sub
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 /etc/texmf/updmap.d/00updmap.cfg
, which should have a line like this:
pdftexDownloadBase14 true
If it’s set to false
, change it to true
, then run update-updmap
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 pdffonts
command). For anything that doesn’t have embedded fonts, you can try the following magical invocation:
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
This creates a file figures/Mprime-new.pdf
that is hopefully identical to the input file figures/Mprime.pdf
, except that the fonts are embedded. Run pdffonts
on it to check.
Once all your figures are in PDF format, remake the paper again. Hopefully, all your fonts are now embedded — check again with pdffonts
.
