Fonts & Character Sets ⇒ Mysterious type 3 fonts appearing in compiled PDF

[zmall88]

I hope someone can help with this: I am preparing a paper to submit at a conference and they have a specific compliance requirement not allowing any type 3 fonts (only type 1). I compiled my latex file and uploaded it to their server and it said I had one type 3 font on a couple of pages (3 out of 8 pages).

I checked the fonts on my PDF, and it seems I have a mysterious F68, type 3, custom encoding font included in my font list. I check the three pages that the font is apparently on and I couldn't find anything out of the ordinary (no graphics either). I also tried searching for this mysterious font F68 but couldn't find anything anywhere on the internet. I'm sure someone must have faced a similar problem but nothing showed up.

I tried troubleshooting my packages and I can't pinpoint the source package that is making this font. My current preamble is:

When I remove both amsmath and amssymb, I get 212 errors and no F68 font (probably because most of the document doesn't compile). If I remove them separately, however, I still get the F68 font.

Also, if I use another class (ifacconf.cls), I still get another type 3 font on the same pages but this time its called F46. This problem has gotten me completely stumped. I would really appreciate any help from anyone on here.

PS: I am using pdflatex (LaTeX => PDF) in a MiKTeX distribution with TeXnicCenter.

Quick check: do you have in your preamble the following line:

\usepackage[T1]{fontenc}

[zmall88]

Actually I didn't have that, so I put it in and compiled the tex file. Its still giving me a type 3 font but this time its F108 instead of F68.

PS: See attached screenshot.

[meho_r]

It would help if you can provide a Minimal Working Example (MWE).

[zmall88]

Since I knew that page 3 had these fonts, I eliminated through a process of bisection, all the lines that made no difference to the output. I get a type 3 font with the code below

Maybe its an issue with \mathbb? Note that the font name is now F61. As I was eliminating the paragraphs/lines, it went from F108 to F62 to F61 as far as I recall. What is going on here?
Here is the ieeeonf class.

Thanks for offering to help.

PS: I have AMSfonts and AMSsymb version 3.0 so Type 1 should be present as a default.

I downloaded IEEEconf.cls file and run your code (with slight changes: "IEEEconf" instead of "ieeeconf", commented out "\overrideIEEEmargins", and added \begin{document}):

The result is in the attachment. No T3 fonts issue here. It is possible that you do not have all necessary fonts installed. Check if these packages are installed: mathptmx, helvet, courier. Also, you may try loading Latin Modern font (\usepackage{lmodern}) or Palatino (\usepackage{mathpazo}) to see how things look then.

[frabjous]

I get the same results as meho_r. Your sample is missing \begin{document}, the class is misnamed, and \overrideIEEEmargins returns an error (as undefined), but if I correct those things, I don't get any Type 3 fonts.

Perhaps it would help to add \listfiles to the code and post your .log file here for comparison. Here's mine, in case it helps.

[zmall88]

I tried everything above I believe. I have a times package that says mathptmx is part of pnfss which I can't find in the repository or on CTAN (it says it comes with the latex distribution). In any case, if I put it as a \usepackage, I don't get an error. I tried using pslatex, altfonts, times, mathpazo, etc.. I still get a type 3 fonts (but now its F122).

Thanks for helping out.

I also isolated the problem to the \mathbb (part of the AMSsymbols/AMSfonts package). I've attached my tex and pdf file.

[frabjous]

\listfiles needs to go at the very beginning of the file, even before \documentclass to work properly; so it didn't provide the nice tidy list I would have wanted, but I still think your .log file is helpful.

When I compile your simpler code (adding \listfiles), I get this log file:

If you open my PDF up, the single embedded font is a type 1 font called "msbm10". Given that, I think the important differences between our log files is the following. Mine has:

Of course, the "dpi600" is a dead give away that it's a rasterized font, since dots per inches doesn't make any sense for Type 1 fonts.

Now, .pfb are type 1 fonts and .pk are type 3 fonts. If I were you, I'd check the fonts\ directory and see if the Type 1 fonts are there, but not being used for some reason, or if you just don't have them installed. You may have version 3 of the amsfonts package, but that doesn't mean you have the latest versions of the fonts themselves.

I don't use MikTeX, and I'm not familiar enough with it to know how you'd go about updating the installed fonts, but maybe you could take it from there.

(Incidentally, if all you need is a quick copy to submit to this conference, you could just use one of the online compilers out there; the one I tried--ScribTeX--gave all Type1 fonts.)
