  • event notifications
  • auctions
  • estate agent boards
  • for sale signs
  • college- or school registration information posters
  • or just plain advertising of a product or a business

 What is Correx?


Correx board is a twin walled extruded polypropylene sheet material with flutes. It could be described as a " plastic cardboard" and it is widely used for street posters. It is treated to make it ink receptive and represents a low cost option for both indoor and medium term outdoor signs.
It is one of the lightest plastic substrates available (Approximately 220 grams per A1 board), and is water-resistant.
It has applications in signage, packaging, printing, advertising, point of sale, storage, transport and general industrial areas.



How is information applied to correx board?

Information is normally applied in three different ways:

  1. screen printed onto the correx board with a specially prepared solvent ink
  2. self adhesive vinyl information prepared as a cut-out and applied onto the correx boards or
  3. digitally printed vinyl that is applied as a layer covering the complete correx board (like a large sticker)

Although full colour work can be digitally printed at high resolution onto vinyl and then applied to correx, this process is comparatively much more expensive than printing directly onto correx.
Although the print resolution is much lower with screen printing the final result is suitable in most circumstances. Street posters are viewed at a distance where the resolution does not make that much difference.


How Durable is Correx?

Correx board is more durable than paper or card-board and has become a well known advertising medium in the streets of perhaps all of our cities. It is water proof and relatively rigid.

(Outdoor durability in South African conditions for correx board is approximately 2 years before it starts becoming brittle from direct sunlight)
