Outdoor posters – Litho & digital print

Our customers use outdoor posters for lots of environments. Petrol forecourts, outside of supermarkets, billboard hoardings and fly posting spots to name a few.  The life expectancy, quantity needed and budget will determine the best way to print your outdoor posters.

Plastic and PVC printing for outdoor posters

The great thing about plastic posters is that they are completely weatherproof and waterproof. However, they are not produced in quite the same way as normal paper posters. Unlike paper, they don’t have a porous surface to absorb the ink. Instead, they have to be printed using special inks that are then dried using UV lamps that sets the ink hard and bonds it to the plastic sheet. They can be digital, silk screen or litho printed depending on the quantity required.

Until recently most plastic posters have been printed on PVC. However, it is not the most economically friendly material as it is not biodegradable or recyclable. Recently, a lot of our posters are produced on polypropylene which is both recyclable and biodegradable (although it does take quite a few years to degrade).

Sometimes people still request PVC though as it is more rigid and has a glossier print surface than polypropylene, which tends to have a slight grain, giving it more of a matt look and feel.

Encapsulated posters

Encapsulation is where paper posters are enclosed in between two sheets of clear printed plastic. It is similar to laminating, but using a thicker plastic film (various thickness options). Encapsulation used to be a lot more popular prior to UV printing onto plastic but is not as popular these days as it tends to be more expensive. It does however, offer a good waterproof protection for outdoor use and offers an extra layer of protection between the print and the sun, wind, and rain.

Billboards and fly posters

Printing for billboards and fly posting is almost always done on 115gsm blue back poster paper. It is white to the print face with an opaque blue on the reverse. The posters are applied to billboard hoardings, usually directly over older advertisements, or in the case of fly posters simply over other older posters, using a strong wallpaper paste.

Why is the backing blue for outdoor fly posters?

The reason for the opaque blue backing is to avoid any show through of the older advertisements pasted underneath.

Lightboxes and outdoor frames

The other popular type of outdoor posters we produce are printed to a standard 150gsm white cartridge paper. You can then mount these into waterproof poster frames. Advertisers then either light it with external lighting onto the frame and poster, or use light boxes where the light is illuminated through the reverse of the poster. Most lightboxes you see outdoors at bus shelters are what we call 6 sheets.
