To ensure best performance against condensation/moisture ingress in outdoor poster advertising, we recommend:

For 1 -3 months life

Wet strength, water resistant or waterproof paper (115–200gsm)
Additives included during paper manufacture prevent the paper from breaking apart when in contact with moisture, ensuring it remains strong and stable. It is often known as blueback paper. These are common specifications for short to medium term poster campaigns and billboard advertising.

For 3 months+ life

Encapsulating a paper poster in thin sheets of clear plastic. This is a common means of protecting posters for outdoor use when water-soluble inks are used. Delivers reliable performance if the encapsulation is made to seal around the whole perimeter of the poster.

Printing onto plastic
Synthetic paper (80 micron minimum thickness polypropylene), sometimes termed 'Poly Poster', or 220 micron PVC are cost effective alternatives for longer-life applications e.g. displaying a business service offer, restaurant menus or repeating seasonal promotions.

     Maximise your poster performance with our design tips

  • Use font in lower case with 80mm+ height for fast recognition.
  • Simple typefaces make your message clearer - avoid serif typefaces and italics.
  • Amplify images and messages by using outline silhouette and drop shadow effects.
  • Reduce heat absorption (solar gain) on outdoor poster signs by limiting regions of dark colour print.
  • Keep text succinct and on point; avoid lengthy passages of text unless it's absolutely necessary.
