Fixing "font not embedded" issue to pass the IEEE PDF eXpress check
We recently had to make the format of a paper complaint with the
IEEE PDF eXpressformat. The paper did not pass the check in the first few attempts.Hence this blog post. I'd like to thank my colleague Ning Shang who didthe most of the fixes to get it working. I am listing the fixes here sothat anyone else who encountered similar issues may find this postuseful.
Before that, I work on Ubuntu 9.04, kile 2.1 (the IDE),use the tools latex, bibtex and dvipdf to generate pdf files fromtex/bib/cls files. (i.e. latex file.tex; bibtex file; (to attach theref.bib file) latex file.tex; dvipdf file.dvi to finally get file.pdf)
The tex file uses the IEEE conference style. Additionally we used the following packages initially:
times, epsfig, graphicx, url, verbatim, amsmath, amsfonts
Issue #1: Document contains bookmarks
Fix: We had to remove the url package from the included packages lists and convert \url{address} to {address} in ref.bib.
Issue #2: Font Times-Italic, Times-Roman, Times-BoldItalic, Times-Bold, Helvetica, Courier is not embedded.
Youcan see what fonts are embedded and what are not, by using "pdffontfile.pdf" and looking at the "emb" column. In our case, it did show thatsome fonts are not embedded.
Fix: We searched the Internet [
1,
2]andfound that in order to fix this (i.e. to embed all the required fonts)we need to do the conversion from tex to pdf in two stages. This is adirty hack; but it works.(file就是file name，例如main.tex文件，file就代表main)
latex file.tex
bibtex file
latex file.tex
latex file.tex (Now we have file.dvi)
dvips -Ppdf -G0 -tletter file.dvi (Now we have file.ps)
ps2pdf -dCompatibilityLevel=1.4 -dPDFSETTINGS=/prepress file.ps file.pdf (Now we have file.pdf)
