Bold Version of CMU Serif Roman / Latin Modern Roman Regular

Question

My current LaTeX document uses the following font for headings, which is either "CMU Serif Bold" by default or "Latin Modern Roman Bold" (the updated version of the CMU font) if you use \usepackage{lmodern}.:

However, I want the following font for my headings (it looks like a different bold version of "CMU Serif Roman" / "Latin Modern Roman Regular"):

Does anyone know how to do this?

EDIT:

After some more research, here is a CV I found on the internet that has implemented the font I want: http://petar-v.com/PetarV-CurriculumVitae.pdf (located at the very top). Maybe this helps someone?

Answer 1

Possibly you want the demi-bold. Hard to say, really - the font properties of the PDF you linked to will tell you for sure.

Here's a comparison of Latin Modern Roman medium, demi-bold and bold extended.

How to do this depends on your engine, which you didn't specify. I used pdfTeX and cfr-lm. Alternatively, use XeTeX or LuaTeX and fontspec.

\documentclass{article}
\usepackage{cfr-lm}
\begin{document}
\plstyle
\begin{tabular}{ll}
  LMR medium & Chapter 1 \\
  LMR demi & \textsb{Chapter 1} \\
  LMR bold extended & \textbf{Chapter 1}
\end{tabular}
\end{document}

CMU also has a non-extended bold serif. Here's a comparison:

\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
\begin{tabular}{ll}
  CMRU medium & Chapter 1 \\
  CMRU demi & \fontseries{b}\selectfont Chapter 1 \\
  CMRU bold extended & \textbf{Chapter 1}
\end{tabular}

\newcommand*\chtest{%
  \begin{tabular}{c}
    \tiny Chapter 1\\\scriptsize Chapter 1\\\footnotesize Chapter 1\\\small Chapter 1\\\normalsize Chapter 1\\\large  Chapter 1\\\Large  Chapter 1\\\LARGE  Chapter 1\\\Huge  Chapter 1
  \end{tabular}%
}
\begin{tabular}{ccc}
  \mdseries\chtest & \fontseries{b}\selectfont\chtest & \bfseries\chtest
\end{tabular}
\end{document}

Answer 2

It appears you're looking for the CM-Super fonts without the effects of package fix-cm, so for the result you ask for, you should remove \usepackage{fix-cm} or similar from your code.

Whether you want that, though, is another matter. As the name suggests, fix-cm corrects design mistakes of the CM-Super packages — in particular, CM-Super is supposed to match Computer Modern, but getting that result requires loading fix-cm. If you want to use the font you ask for just for chapter headings, without altering the rest of the document, you probably can with the right low-level font selection commands. But using Latin Modern Demibold, as in the other answer, is probably a better choice, as Latin Modern is considered by most a higher-quality design.

MWE:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
%\usepackage{fix-cm} % Don't load this for the font you asked for. 

\begin{document}
\Huge\bfseries
Definition.

Without fix-cm, the main font is called SFBX2488 in the PDF, as shown by pdffonts, where BX stands for bold extended, and 2488 means, IIUC, that the design size is 24.88pt. Some PDF viewers show properties of the embedded fonts in a "Fonts" dialog somewhere, among PDF properties or such.

While CM-Super uses scalable (Type 1) fonts, many fonts have multiple designs, optimized for different sizes — that's what it means to have design size 24.88pt.

With fix-cm, the main font is called SFBX1200 in the PDF (where 1200 means, IIUC, that the design size is 12pt, though the font has been scaled). That's because Computer Modern uses its variant with design size 12pt also at bigger sizes, and fix-cm ensures CM-Super does the same to obtain results matching Computer Modern.

$ pdffonts pdfgentounicode-mwe.pdf
name                                 type              encoding         emb sub uni object ID

The original file uses many fonts, including the above mentioned SFBX2488, but also other design sizes of SFBX, which seem consistent with CM-Super.
