[Tex/LaTex] How to Tikzposter be used to create a poster with multiple pages

posterstikzposter

I'm trying to create a poster using Tikzposter with the following code:

\documentclass{tikzposter} % See Section 3
\input{Settings/Packages.tex}
\input{Settings/Administrative.tex}

\title{\myTitle} \institute{} % See Section 4.1
\author{Emanuel Enberg} \titlegraphic{\includegraphics[]{Files/MID_RGB.png}}
\usetheme{Autumn} % See Section 5
\usecolorstyle{Britain}

\renewcommand\thesection{}
\renewcommand\thesubsection{\arabic{subsection}}

\begin{document}

\maketitle
\begin{columns}


\column{0.37}% Width set relative to text width
\block{Abstract}{\input{Chapters/Sections/AbstractContents.tex}}
\block{Inledning}{\input{Chapters/Sections/Chapter1_Section1_Inledning.tex}}

\column{0.63}
\block{Syfte \& frågeställning}
{\input{Chapters/Sections/Chapter1_Section2_Syfte-och-fragestallningar.tex}}
\block{Bakgrund \& tidigare forskning}
{\input{Chapters/Sections/Chapter1_Section3_Bakgrund-och-tidigare-
forskning_Part1.tex}}

\begin{subcolumns}
    \subcolumn{0.465} 
    \block{Nervcell}{\input{Chapters/Sections/Subsections/Chapter1_Section3_Subsection1_Nervcell.tex}} 
    \block{Maskininlärning}{\input{Chapters/Sections/Subsections/Chapter1_Section3_Subsection2_Maskininlarning.tex}}

    \subcolumn{0.535} 
    \block{Vektorer \& matriser}{\input{Chapters/Sections/Subsections/Chapter1_Section3_Subsection3_Vektorer-och-matriser.tex}}
    \block{Artificiell neuron, del 1}{\input{Chapters/Sections/Subsections/Chapter1_Section3_Subsection4_Artificiell-neuron_Part1.tex}}
\end{subcolumns}

\end{columns}


%%%%%% HERE I WOULD NEED TO MAKE A NEW PAGE/POSTER


\end{document}

This code gives me the following output:

enter image description here

However, as you can see in the image, I can't fit all of the content on a single page. I figure I would need at least 3 pages in total.

So far I've tried using \newpage and placing more blocks after. However, that gives me with some nasty errors.

I have considered making separate documents for each page, but that would mean I can't reference figures and equations from other pages.

Is there any way to generate a poster with multiple pages using Tikzposter? If not, is there any other package with similar functionality to Tikzposter which would allow me to do so?

Best Answer

This shows how to use the xr package to link two tikzposters. The tricky bit was making the equation numbers continuous.

First poster (test5.tex):

\documentclass{tikzposter}
\usepackage{xr}
\externaldocument{test6}

\makeatletter
\AtEndDocument{\immediate\write\@auxout{\string\newlabel{lasteq}{{\arabic{equation}}{\thepage}}}}
\makeatother

\begin{document}
\block{First page}{\begin{equation}\label{first}
x=a
\end{equation}
See equation (\ref{second})}
\end{document}

Second poster (test6.tex):

\documentclass{tikzposter}
\usepackage{refcount}
\usepackage{xr}
\externaldocument{test5}
\AtBeginDocument{\setcounter{equation}{\getrefnumber{lasteq}}}
\begin{document}
\block{Second page}{\begin{equation}\label{second}
y=b
\end{equation}
See equation (\ref{first})}
\end{document}
