Tikzposter: Long list of authors breaking in two lines

Question

I have a problem with a long list of authors. I don't want to beak the name between last name and given name. What I mean is shown for Author "AuthorForThis ABCeAAAAAAAA1" How can I avoid this?

Wishes, Mike

\author[1]{AuthorForThis ABCa}

Answer 1

I think all you want for this is to use a non-breaking space between the two parts of the author name, i.e. \author[1]{AuthorForThis~ABCeAAAAAAAA1} using ~ rather than will produce a non-breaking space, preventing a linbreak occuring between the first and second names (see When should I use non-breaking space? for example for a bit more on the usefulness of the non-breaking spaces).

\author[1]{AuthorForThis~ABCeAAAAAAAA1}

Answer 2

Personally i find the codde very very complicated. Titles often need some manual adjusting, especially for a poster, you can do it b hand more easy.

\documentclass[25pt, a0paper, portrait,margin=0mm, innermargin=15mm]{tikzposter}
\newcommand{\ini}{\textsuperscript{1}}
\newcommand{\inii}{\textsuperscript{2}}
\begin{document}

\block{}{
        \centering
        \color{titlefgcolor}
        \vspace*{1em}
        {\bfseries \Huge The Journey of Walter Wombat \par}
        \vspace*{3em}
        {\huge Carl Capybara\ini, Lazy Lizard\ini, Busy Bee\inii, \par Gabrielle Giraffe\ini, Laura Lion\ini ~and Klaus Koala\inii  \par}
        \vspace*{1em}
        {\LARGE \ini Institute of Applied Duck Dance\par
        \inii Institute of Experimental Duck Dance\par}
        \hfill\llap{\smash{\includegraphics[width=.1\linewidth]{example-image}}}\par
}

\block{Introduction}{
    This will be a great story.
}

\end{document}
