What is a PDF?

PDF stands for Portable Document Format and creating a PDF file from a Word or PowerPoint or Excel file is like wrapping the file in a safe seal. It means that we won’t be able to change anything on your poster either by accident or by design. It’s a way of making sure that we print what you expect us to print.

PrimoPDF is a free PDF creator tool which you install on your computer as though it’s  another printer. It’s good because it works and it’s dead easy to use! You can find out more here
