The current question is a follow-up to some previously asked questions, like this: It is possible to make fonts appear heavier (darker) in pdf output of Latex? and this: Make entire document heavier using pdfrender and this: Fake bold in LuaLaTeX. All of these questions deal with the document as a whole (equally text and math). In my case, I need to make only math font a bit thicker (darker). I use times for text and CM for math. The former is much heavier than the latter and they just look horrible. My goal then is to make CM math a little bit darker to shorten that gap. Is there a way to fix this? Thank you.

EDIT:

I add a not-so-minimal working example here showing my real usage as asked by some commentators. I use MiKTeX on Windows and I run pdflatex directly to obtain a pdf file:

  • Try \mathbf and \boldsymbol. – Andrew Apr 2 '15 at 0:44

    Check the LaTeX Font Catalogue, specifically the Fonts with math support. Choosing any of these will show you examples of text, maths, and available styles. – erik Apr 2 '15 at 0:46
  • @Andrew - And how to differentiate between bold and non-bold? – AboAmmar Apr 2 '15 at 0:46
  • @erik - I searched that Catalogue, but I'm not satisfied with any of the choices there. I'm looking for a new way to define math font as the attempts in the links of my question. – AboAmmar Apr 2 '15 at 0:49

    @AboAmmar - Have you checked out the newtxtext and newtxmath packages? They're definitely free, as is tge mathptmx package? – Mico Apr 2 '15 at 1:53

Comptuer Modern is intentionally light. It is better to choose a math font corresponding to your main text.

There is a package mathptmx in the psnfss bundle that sets the main text to ptm and fakes some corresponding math fonts. Using this gives better results than you are seeing. However, better would be to switch to a more modern solution provided by the newtxtext and newtxmath packages. Below are examples of each.

mathptmx

Sample mathptmx

\documentclass[a4paper,oneside,12pt,table]{book}

\usepackage[T1]{fontenc}
\usepackage{amsmath,amssymb,amsfonts}
\usepackage{textcomp}
\usepackage{mathptmx}
\usepackage[scaled=0.92]{helvet}
\usepackage{microtype}

\begin{document}
\chapter{Introduction}
\section{First Section}
Some text which is OK! and some math which is the same weight:

\begin{equation}\label{e:barwq}
\begin{split}
H_c &=\frac{1}{2n} \sum^n_{l=0}(-1)^{l}(n-{l})^{p-2}
\sum_{l _1+\dots+ l _p=l}\prod^p_{i=1} \binom{n_i}{l _i}\\
&\quad\cdot[(n-l )-(n_i-l _i)]^{n_i-l _i}\cdot
\Bigl[(n-l )^2-\sum^p_{j=1}(n_i-l _i)^2\Bigr].
\end{split}
\end{equation}

\end{document}

newtxtext with newtxmath

Sample newtx

\documentclass[a4paper,oneside,12pt,table]{book}

\usepackage[T1]{fontenc}
\usepackage[helvratio=0.92]{newtxtext}
\usepackage{newtxmath}
\usepackage{microtype}

\begin{document}
\chapter{Introduction}
\section{First Section}
Some text which is OK! and some math which is the same weight:

\begin{equation}\label{e:barwq}
\begin{split}
H_c &=\frac{1}{2n} \sum^n_{l=0}(-1)^{l}(n-{l})^{p-2}
\sum_{l _1+\dots+ l _p=l}\prod^p_{i=1} \binom{n_i}{l _i}\\
&\quad\cdot[(n-l )-(n_i-l _i)]^{n_i-l _i}\cdot
\Bigl[(n-l )^2-\sum^p_{j=1}(n_i-l _i)^2\Bigr].
\end{split}
\end{equation}

You should also have a look at the mathtime (mtpro2) fonts. The fonts are commercial, but one only has to pay for the full set, which most people don't need. The fonts are better in some ways (eg kerning) than some alternatives.

  • ,@JPi I already know about mtpro2 and use it some times in less-math demanding documents, but, this is a long document with heavy math (vectors, bold Capital Greek symbols, ...), so, the lite version of mtpro2 will be by no means sufficient. – AboAmmar Sep 7 '15 at 11:07
  • ok. (I've paid the $75.) – JPi Sep 7 '15 at 13:48
