I am a beginner in LaTeX and I am not able to resolve the problem. Hopefully, I will get the help here.

I have the following code:

 documentclass[12pt]{article}

 usepackage{newtxtext,newtxmath}

 usepackage{authblk}

 renewcommand{Authfont}{fontsize{12}{14.4pt}selectfont}

 renewcommand{Affilfont}{fontsize{10}{12}selectfont}

 begin{document}

title{textbf{Preparation of Papers for IEEE Sponsored Conferences & Symposia}}

author{Navdeep Singhtextsuperscript{a}, Lakhwinder Kaur textsuperscript{b}, Kuldeep Singh textsuperscript{c}}

affil[a,b]{Dept. of Computer Science & Engg., Punjabi University, Patiala, 147001, Punjab}

affil[c]{Bharat Electronics Ltd, Ghaziabad, U.P, India}

date{}

maketitle

end{document}

and it gives the following output:

Here as we can observe the superscript on the last author's name contains an unwanted '1'. I am not able to find out what is the mistake in my code. Please help me locate it.

Another question I would like to ask is based on the following 2 commands

documentclass[12pt]{article}

renewcommand{Authfont}{fontsize{12}{14.4pt}selectfont}

Both the commands say that the font size is 12pt then why is the font size of title and authors different? I know they both belong to different packages but a given font size of 12pt should remain the same? Isn't it right?

What if I am told by the journal to use a font size of 12pt, how can I be sure which one is right to use. Please advise me.

You should set the footnotemarker with the optional argument of author:

 documentclass[12pt]{article}

 usepackage{newtxtext,newtxmath,lipsum}

 usepackage{authblk}

 renewcommand{Affilfont}{footnotesize}

 renewcommand{Authfont}{normalsize}

 renewcommandAuthands{, }

 begin{document}

title{textbf{Preparation of Papers for IEEE Sponsored Conferences & Symposia}}

author[a]{Navdeep Singh}

author[b]{Lakhwinder Kaur}

author[c]{Kuldeep Singh}

affil[a,b]{Dept. of Computer Science & Engg., Punjabi University, Patiala, 147001, Punjab}

affil[c]{Bharat Electronics Ltd, Ghaziabad, U.P, India}

date{}

maketitle



lipsum

end{document}

The title is larger than 12pt.
