How can I prevent newtx to change fonts format in `\section{}` and `\subsection{}`?

Question

From https://tex.stackexchange.com/a/659813/127048 ; I have been recommended to use newtx

If you use IEEEtran, I recommend using newtx in order to get Times font also in math

When I add \usepackage{newtx} into following template (2n line) the font format changes for the text inside \section{*} and \subsection{*} also for \lstinputlisting[] , it becomes much bolder. I am not sure those changes would be accepted by the corresponding journal.

Is it possible to prevent newtx to change font format for the \section{} and \subsection{}?

Answer 1

Compare what you get from IEEEtran without and with newtx.

You can clearly see that the in the top image the smallcaps letters are obtained by scaling uppercase, which makes the vertical strokes thinner than in capital letters. This doesn't happen in the bottom picture, where a true smallcaps font is used and you can see that the vertical strokes have the same width.

The same for the smallcaps near the dropcap letter.

Anyway, if you prefer the inferior output, just do

\usepackage{newtxmath}

that will only make math compatible with Times and fix the unsightly default behavior of IEEEtran that uses Computer Modern for math, which is visually clashing with Times.

Slightly more complicated is to get lining numbers in the \section headers.

\documentclass[10pt,journal,compsoc]{IEEEtran}
\usepackage{newtx}
\makeatletter
% standard way to add commands for printing the section number
\renewcommand{@seccntformat}[1]{%
  % if \numberfont@<level> is defined, use it in a group
  \ifcsname numberfont@#1\endcsname
    % if \numberfont@<level> is defined, use it in a group
    {@nameuse{numberfont@#1}@nameuse{the#1}}%
  \else
    % otherwise do the standard
    @nameuse{the#1}%
  \fi
  % add the standard space
  \quad
}
\newcommand{\definenumberfont}[2]{%
  @namedef{numberfont@#1}{#2}%
}
\makeatother
% we want to add \upshape for the \section level, so the figures are lining
\definenumberfont{section}{\upshape}
