I am using the latex template of IEEE ACCESS (i.e., \documentclass{ieeeaccess})officially provided by the IEEE template selector. However, when compiling I get the warning that certain fonts are missing.

Font shape 'T1/ptm/n/n' undefined
(Font) using `T1/ptm/m/n' instead.

Font shape 'T1/phv/n/n' undefined
(Font) using `T1/phv/m/n' instead.

And I dig into the log file, which shows:

LaTeX Font Info: Trying to load font information for T1+ptm on input line 36.
("/Users/***/Library/Application Support/MiKTeX/texmfs/install/tex/latex/psnfss/t1ptm.fd"
File: t1ptm.fd 2001/06/04 font definitions for T1/ptm.

LaTeX Font Info: Trying to load font information for T1+phv on input line 55.
("/Users/hurunqiu/Library/Application Support/MiKTeX/texmfs/install/tex/latex/psnfss/t1phv.fd"
File: t1phv.fd 2020/03/25 scalable font definitions for T1/phv. )

I suppose pdfLaTeX is searching the fonts in T1/ptm and T1/phv. Looking inside one of the two files(T1/ptm.td) I found:

\ProvidesFile{t1ptm.fd}
   [2001/06/04 font definitions for T1/ptm.]

\DeclareFontFamily{T1}{ptm}{}


\DeclareFontShape{T1}{ptm}{m}{n}{
   <-> ptmr8t
}{}


\DeclareFontShape{T1}{ptm}{m}{sc}{
   <-> ptmrc8t
}{}


\DeclareFontShape{T1}{ptm}{m}{sl}{
   <-> ptmro8t
}{}


\DeclareFontShape{T1}{ptm}{m}{it}{
   <-> ptmri8t
}{}


\DeclareFontShape{T1}{ptm}{b}{n}{
   <-> ptmb8t
}{}


\DeclareFontShape{T1}{ptm}{b}{sc}{
   <-> ptmbc8t
}{}


\DeclareFontShape{T1}{ptm}{b}{sl}{
   <-> ptmbo8t
}{}


\DeclareFontShape{T1}{ptm}{b}{it}{
   <-> ptmbi8t
}{}


\DeclareFontShape{T1}{ptm}{bx}{n}{<->ssub * ptm/b/n}{}
\DeclareFontShape{T1}{ptm}{bx}{sc}{<->ssub * ptm/b/sc}{}
\DeclareFontShape{T1}{ptm}{bx}{sl}{<->ssub * ptm/b/sl}{}
\DeclareFontShape{T1}{ptm}{bx}{it}{<->ssub * ptm/b/it}{}


\endinput

There is indeed no combination of ptm/n/n.

Meanwhile, I checked ieeeaccess.cls provided by official, and found one line \def\bioaddressfont{\sffamily\putfont{T1}{formata}{n}{n}{8}{10}}.

I believe it's here that requires the font ptm/n/n and phv/n/n.

I thought I could neglect the warning if the substituted fonts are OK. However, seeing the published paper, I found the font of the bold titles(including subsections) are indeed different from mine now:

The published articles: enter image description here

Mine currently: enter image description here

I think I shouldn't change the template, and I found no ptm/n/n font solutions online, so where went wrong? How can I make it right?

(P.S. I have tried both pdfLatex and MiKteX, and both couldn't work.)

  • Wow, that class (at least the one I found on github) contains a lot of \fontseries{n} instructions. That's utter nonsense. – campa Nov 24 '20 at 12:52
  • Welcome to TeX.SE! Note that if your paper gets published then the editors of the journal will fix this kind of issues to make all papers are conforming to the official template, therefore you don't necessarily need to fix this yourself. – Marijn Nov 24 '20 at 12:57
  • @campa Yes. I think n/n makes no sense since I found a lot of people unable to find m/n. I literally don't know how the template was given. BTW, what do these parameters mean, especially the last two slashes? – BobHU Nov 24 '20 at 12:58
  • @Marijn That might be true, but a journal template with font errors and an official template which yields dozens of bad boxes is quite depressing... BobHU Explaining font selection is too long for a comment you might want to give a look at section 2 of the LaTeX font guide. – campa Nov 24 '20 at 13:06
