[Tex/LaTex] Multiple Authors in scrartcl

koma-scripttexmakertitles

I have the following code in the document portion and I can't seem to get \and to work with it – I'm assuming that it's due to something specific to using this class?

\begin{document}
% ------------------------------------------------------------------------------
% Maketitle
% ------------------------------------------------------------------------------
%\maketitle
\thispagestyle{empty}               % Remove page numbering on this page

\printtitle                                 % Print the title data as defined above
\vfill
\printauthor                                % Print the author data as defined above
% ------------------------------------------------------------------------------
% Begin document
% ------------------------------------------------------------------------------

% ------------------------------------------------------------------------------
% End document
% ------------------------------------------------------------------------------
\end{document}

I tried using \maketitle but that just messes up how my document looks so I'm wondering if there is another way to do this?

Best Answer

You are using a non-standard way to display title and author information. The standard scrartcl stores the authors in \@author and prints them out in a table environment. The standard definition of \and is designed to provide the approriate command there. With your \printauthor macro you should provide a corresponding definition of \and for your set-up. Most appropriate seems to be to provide some vertical space, e.g. via

\renewcommand{\and}{\vspace{1cm}}
