Some practical advice

QR Codes

Despite their apparent advantages, QR codes aren’t very practical on posters. This is due to the duration of the display and the distance between the screen and the target audience. A person who sees a poster whose content interests him or her will have little time to be able to properly scan the code.

Short URLs

You can create a short URL that’s easy to read and remember, such as go.epfl.ch/openscience.

Text

  • Keep text to a minimum
  • Use standard fonts (Verdana, Arial, Helvetica, etc.)
  • Use large font sizes
  • Ensure good contrast with the background to make text clearly legible even from a distance

Images

  • Use good quality images (resolution) as they will be displayed on large screens.
  • In contrary to text, use images with relatively smooth tones and contrasts.
  • Make room for spaces. Empty spaces can make your poster more legible.

Frequently Asked Questions

A poster remains visible for 20 seconds. At certain times of the year (end of spring semester, end of the year) when the demand for posters is very high, we may reduce the duration to 15 seconds.

In most instances no, we do not accept requests in excess of 21 days or we reduce the posting period.

Exceptions are made for matters concerning campus security or other institutional information.

We don’t recommend any special tools. What’s important is that the images are the right size (1920 x 1080) and in JPEG format.

Among the software programs licensed by EPFL, you can use PowerPoint, Illustrator and Photoshop.

If you need to crop or add text to an image, you can use MS Paint (Windows) or Preview (Mac OS), which are automatically installed on your machine.

We don’t currently provide specific templates for posters. However, Mediacom does provide presentation templates that you can use or that may serve as inspiration. Authentication is required to access these templates.

Yes, absolutely. We are happy to help you create your image.

Please bear in mind, however, that this is a “best effort” service that should not be treated as a matter of urgency. Contact us well in advance to ensure that we can actually help you.
