different rendering of two different documentclasses

The rendering above the red line(zoomed in) was a result of: \documentclass[journal]{IEEEtran}

The rendering below the red line(zoomed in) was a result of: \documentclass[journal]{AIAA}

Why is there such a huge difference? Can I change something in the AIAA class file so that it yields results similar to the IEEEtran class file?

    I do not have AIAA.cls, but it clearly uses bitmap fonts. Not having the document class, I am not going to provide you with a definite answer, but perhaps take a look at this article: dsanta.users.ch/resources/type1.html – Harold Cavendish Oct 31 '11 at 9:24

    We also have a few questions related to this issue (bitmap fonts) on this site. For example, tex.stackexchange.com/q/1291/86 seems relevant. You'll find more if you search for bitmap fonts. – Loop Space Oct 31 '11 at 9:26

    Also note that there appears to be a newer version aiaa-tc.cls since 2004 which uses vector fonts by default (\documentclass{aiaa-tc}). Documentation: tug.org/texlive/Contents/live/texmf-dist/doc/latex/aiaa/… – Harold Cavendish Oct 31 '11 at 9:32
  • @HarroldCavendish: I believe this could be an answer. – Andrey Vihrov Oct 31 '11 at 9:49
  • @Andrey Vihrov: I shall wait for the OP's word before writing and answer because I am a little unsure whether the aiaa-tc class is what he is looking for – it creates a single column article, while the aiaa a two column one. Most recent journal articles downloaded from the AIAA website feature a two column layout and the new class is most probably intended only for technical conference papers. From what I have read, it appears that aiaa.cls was used only for simulating journal appearance. The only official template that the AIAA provides is called “AIAA Meeting Papers Template”. – Harold Cavendish Oct 31 '11 at 10:13

After downloading the LaTeX template containingaiaa.clsfrom the AIAA official website and installing a couple of obsolete packages, most importantly dropping, I have found that the output uses vector Type 1 fonts.

The solution is therefore, as suggested by Stefan Kottwitz, in Why are Bitmap-Fonts used automatically? to install the cm-super package.

However, the aiaa.cls seems to be obsolete, which is indicated even by its placement in a folder named pre2004. Therefore I recommend usingaiaa-tc.clswhen possible.

    And someone should contact the AIAA to update their LaTeX class. LaTeX really isn't rocket science. :-) – Martin Schröder Oct 31 '11 at 11:18
  • I had some issues with aiaa-tc.cls.... Therefore I think I will continue with aiaa.cls for the present... The problem with cm-super is that Latex is not able to find it. Just installed it using the package-manager but still it doesn't recognize cm-super. :( – Shashank Sawant Oct 31 '11 at 14:27
  • @ShashankSawant Might be a silly question, but did it or you run updmap-sys? – Harold Cavendish Oct 31 '11 at 15:39
  • @HarroldCavendish How to run updmap-sys? Thanks for your previous advice! :) – Shashank Sawant Nov 1 '11 at 15:56
  • You could also use Latin Modern, same typeface, but with updated kerning and support for more languages. – Canageek Nov 4 '11 at 6:33
