Creating a poster is relatively simple. Latex, Open Office (particularly, Open Office Draw), and most other packages can create PDFs in paper sizes up to at least A0. Generally:
- Aim to convey just the main ideas of your paper.
- A corollary to the above: don't put in large amounts of text or equations and so on. The details should be in your paper.
- Use colour, but make sure your text is readable.
- Be creative in your design. You don't have to stick to a bunch of boxes with text.
Getting a poster printed may be more work than creating it in the first place.
- An online printer, such as http://1clickprint.com, is likely to be cheapest but will take about a week to produce the poster
- The University's CentralPrint (http://www.centralprint.bham.ac.uk/) is on campus
- Service Point (http://www.servicepointuk.com/) is next to Five Ways train station, is reasonably priced, and most importantly has a 24-hour while-you-wait service
- KallKwik (http://www.kallkwik.co.uk/birmingham/) do while-you-wait printing
- The University's Space Research department (http://www.sr.bham.ac.uk/~mpc/p2/plotter/) also do large format printing for a reasonable price, submit online
