The basic idea is to do this:
- Select the mind map figure in Curio.
- Choose File > Export Selected Figures As > PDF and enter a file name.
- Launch Tiler and open that PDF.
- In Tiler, choose the number of pages horizontally and vertically to scale your PDF across.
- Print.
Then stitch the individual sheets together with tape or glue to create your poster or banner. Very slick!
If you need something a bit more professional looking: local or Internet print shops should be able to produce a large-format poster given a PDF, as well.
