Imperial College London provides a set of Competition Poster Templates with official colour-scheme and branding guidelines.
Here we provide LaTeX versions of these templates, which use the beamer poster theme created for Imperial College by Lian Tze Lim (Overleaf).
To start working on your poster, simply click the 'Open as Template' button above. You'll be able to set up your template to use any of the four official Imperial College London poster colour-schemes:
Black
Dark Blue
Light Blue
White
The template also provides the option to toggle between different sizes (e.g. A0, A1) and different orientations (portrait, landscape) as required.
The example poster shown on the right uses the White colour-scheme, and is set to be A0, portrait by default.
Metropolis is originally created by Matthias Vogelgesang and is available from https://github.com/matze/mtheme as well as CTAN. More information about the theme, including the design principles, can be found at http://bloerg.net/2014/09/20/a-modern-beamer-theme.html. This version demonstrates the use of a progress bar under the frame titles. See the manual for other customisation options.
This is an unofficial Indian Institute of Technology Bombay Beamer Presentation Template (modified version). Feel free to use it, modify it, and share it.
