computer-modernieeetranmathbb
This is really a mystery for me — how to make up the following equations, which are very common in IEEEtran:
Another example:
They look quite similar to the standard CM font in latex, but not exactly the same. I tried many other fond packages but none of them produce like that. Especially, the \mathbb{} seems different and other symbols look more compact.
This post on a german typography board provides a possible solution for this problem. The OP also gives a snippet of Knuth's 'Digital Typography' to show that the CM was never meant to look that thin in print (as it does with modern laser printers; see third snippet).
Another workaround – although kludgy – would be to use a different optical size for standard text. If you set the text in 11pt, the default optical size is 10pt. Choosing 9pt instead will result in slightly thicker strokes but also a slightly wider letter shape.
Some options include these (see examples below):
Use "Latin Modern" (\usepackage{lmodern}), the updated version of Computer Modern. It looks a bit less spindly on screen and print than the original, in my opinion. (Example below)
Scale "Computer Modern" as demonstrated below (thanks to this answer)
Use the font "Computer Concrete" (\usepackage{concmath}), which Knuth designed as a thicker version of Computer Modern using METAFONT.
Use a similar but thicker font. For example gfsbodoni (\usepackage[default]{gfsbodoni}) is in the same family of "modern" typefaces but perhaps has a more desirable weight.
Use METAFONT directly and adjust it to your liking. This kind of thing was the original purpose of that program.
(EDIT)
Demonstration of font scaling (#2 above):
Here is a way that you can scale the font. You ask for a smaller font size to be magnified to a larger one; since the smaller sizes have thicker strokes, you get a thicker-looking, but also wider font. You can experiment with the proportions. This example scales cmr7 up to the default 10pt.
(I didn't get the italic working yet, and I don't think the bold is scaled, but hopefully someone else can add to this.)
\documentclass{article}
\usepackage[T1]{fontenc}
\DeclareFontShape{T1}{cmr}{mx}{n}%
{<->cmr7}{}
\DeclareFontShape{T1}{cmr}{mx}{it}%
{<->cmr7}{}
\AtBeginDocument{%
\fontseries{mx}\selectfont%
}
% to create dummy text for testing
\newcommand{\quickfox}{The quick brown fox jumps over the lazy dog}
\newcommand{\Fox}{The Quick Brown Fox}
\newcommand{\Dog}{The Lazy Dog}
\newcommand{\Jumps}{Jumps Over}
\usepackage{lipsum}
\begin{document}
\section{\Fox}
\quickfox?
\subsection{\Dog}
\emph{\quickfox.}
\paragraph{\Jumps}
\lipsum[1]
\end{document}
Thus, cmr7 scaled to 10pt:
For comparison, here is the example with lmodern and no scaling:
This is gfsbodoni:
And this is concmath (Computer Concrete) (as noted in the comments it really is in a different font family despite being derived from Computer Modern):
(EDIT)
Here is a very basic demonstration of how to get started modifying a Metafont. (It's my first time doing it so take this with a grain of salt.)
TEXMF-DIST/fonts/source/public/cm/crm10.mf.cmthick.mf
thin_join#:=10/36pt#; % width of extrafine detailstexdoc metafont):
mf '\mode=localfont; input cmthick'gftopk cmthick.600gfUse the new font. Since this was just for demonstration and I don't know what I'm doing, I just did this in Plain TeX. File cmthicktest.tex:
The quick brown fox jumps over the lazy dog.
\font\cmthick=cmthick
\cmthick
The quick brown fox jumps over the lazy dog.
\bye
Compiled with tex cmthicktest && dvips cmthicktest && ps2pdf cmthicktest.ps I get the following:
This is just to show that it can be done. I don't know if this is the right way.

The screenshots you posted feature the following fonts
Times Roman(upright) [default forIEEEtrandocument class]Computer Modern[also the default]FourierorBoondoxAs @egreg has already pointed out in a comment, this font combination is anything but successful. In fact, the combination is poor. Compare, e.g., the form of the digit
1in the equations with the form on the final line of text. Observe that Computer Modern almost looks "spindly" and thin next to the darker, less contrastyTimes Roman. The serif-styleComputer Modernfont doesn't harmonize with the sans-serif blackboard-bold lettersEandP.I you must use the
IEEEtrandocument class -- and hence are stuck with Times Roman as the main text font -- I suggest you not specify the document class optiontimes; doing so will load the obsoletetxfontspackage. Instead, load the packagesnewtxtextandnewtxmathvia\usepackagestatements.For the sake of completeness, here's the code that generated the screenshots shown above.
