An example of a decent poster:

What’s good: clear graphics, limited text, something one could read quickly if needed that tells the whole story. I highly recommend a white background (faster and cheaper to print than colored background posters.)

 

What could be better—the drug delivery part is clearly just plopped in. One doesn’t need a lot more text, but it would be good to have a bit more context.

 

Coatings can make the poster to reflective in a huge conference hall.
