# [Tex/LaTex] How to keep multiple authblk affiliation in tikzposter in one line

authblktikzposter

I came across this example that shows how to use affiliations in tikzposter using authblk package.

I would like to do something similar, but having several institutions with relatively short names – I would like to save space on the top of the poster and keep them in one line.

How can that be achieved?

#### Best Answer

Add the following lines after loading the package authblk.

\usepackage{authblk} % improved author and affiliation design
\makeatletter
\renewcommand\maketitle{\AB@maketitle} % revert \maketitle to its old definition
\renewcommand\AB@affilsepx{\quad\protect\Affilfont} % put affiliations into one line
\makeatother
\renewcommand\Affilfont{\Large} % set font for affiliations


\documentclass[25pt]{tikzposter}
\usepackage{authblk} % improved author and affiliation design
\makeatletter
\renewcommand\maketitle{\AB@maketitle} % revert \maketitle to its old definition
\renewcommand\AB@affilsepx{\quad\protect\Affilfont} % put affiliations into one line
\makeatother
\renewcommand\Affilfont{\Large} % set font for affiliations
