# Is there any way other than \pmb to produce bold greek letters when mathptmx is used?

I know that mathptmx does not contain bold symbols for greek letters in math mode, and the result of \pmb is too ugly. Is there a way to specify LaTeX to use CM fonts for bold greek letters when mathptmx is used?

To use Computer Modern for bold Greek letters, you can put the following into the preamble of your document:

\usepackage{amsmath}
\SetSymbolFont{letters}{bold}{OML}{cmm}{b}{it}
\SetSymbolFont{operators}{bold}{OT1}{cmr}{bx}{n}


To typeset a bold \Gamma, you can then write \boldsymbol{\Gamma}. That said, the result looks mixed because the regular weight of Times already looks pretty heavy compared to Computer Modern.

Incompatibility with amsmath sounds like a pretty awful setback. –  levesque Nov 19 '12 at 0:52
@levesque - could you elaborate on your claim that mtpro2 is incompatible with amsmath? I've been using the two packages for years, and I'm not aware of incompatibilities. –  Mico Apr 6 at 5:15
