I've seen various topics here adressing how to turn math symbols bold, but none of them gives a suitable option for \mathbb
characters, as in \mathbb{ABC}
.
I have tested some options to see which commands turn which symbols in bold. Here is my code:
\documentclass{article}
\usepackage{amsmath} % some math-related packages, not sure which of them are necessary
\usepackage{amssymb}
\usepackage{amsfonts}
\usepackage{bm} % for \bm
\usepackage{fixmath} % for \mathbold
\begin{document}
\section{Some text $\mathbb{ABC}abc\cosh\div+\alpha$ some text} %1
\section{Some text $\boldsymbol{\mathbb{ABC}abc\cosh\div+\alpha}$ some text} %2
\section{Some text $\mathbf{\mathbb{ABC}abc\cosh\div+\alpha}$ some text} %3
\section{Some text $\pmb{\mathbb{ABC}abc\cosh\div+\alpha}$ some text} %4
\section{Some text $\boldmath{\mathbb{ABC}abc\cosh\div+\alpha}$ some text} %5
\section{Some text $\bm{\mathbb{ABC}abc\cosh\div+\alpha}$ some text} %6
\section{Some text $\mathbold{\mathbb{ABC}abc\cosh\div+\alpha}$ some text} %7
\end{document}
(The absence of \div
in numbers 2 and 6 are not typos, neither is the 'ff' in number 3.) Apparently \pmb
is the only command which turns \mathbb{ABC}
bold. But it makes the characters quite ugly, take a close look: (on the right is the normal version)
If no alternative shows up, I think I'll just use \pmb
for the \mathbb
characters and \boldsymbol
or something for the others.
Is there any alternative to turn
\mathbb{ABC}
bold?

Here I place three copies in close horizontal proximity by defining
\fakebold{}
. One can obviously modify it to use more copies, or to apply vertical offset as well. The horizontal offset is given by\bshft
, currently set to 0.18pt.By using the
\ThisStyle{...\SavedStyle...}
feature ofscalerel
, it should work across math styles, so that$\fakebold{A_b} A_{\fakebold{b}} A_b$
will give the expected result.and a close-up:
