The first question to ask yourself is whether your signs are to be used indoors or outdoors. Indoor signs can be made of lighter materials such as foam PVC or standard acrylic. Outdoor signs on the other hand need to be made of weather resistant materials that can withstand change in temperature and rain. Aluminium composite (often referred to as dibond) and cast acrylic are 2 of the most common materials used for exterior signs and work well in the British weather.
Matching the Substrate to the Job
Foam PVC is the lightest and cheapest of the substrates we use. It’s great for short term displays etc. Dibond is a two thin aluminium sheet bonded to a polyethylene core. It’s the perfect material for a permanent exterior sign. It’s rigid and weather resistant making it a great choice. Timber is also a great option for signs, particularly for traditional or boutique style shops. However, timber must be sealed properly to make it weather resistant. Acrylic is also a great option for illuminated signage and premium quality indoor signage.
Finish and Longevity
A glossy finish looks fantastic initially but is far more prone to scratching and wear than a matt or satin finish. When printing on outdoor signs it is vital to laminate the graphics to prevent fading. For businesses based in coastal or exposed areas around Exeter, it is vital to use UV-resistant inks and laminates – these may cost a little extra but are a practical necessity rather than a luxury.
How the Sign Will Be Fixed
The fixings that hold your sign together are as important as the material itself. There are heavy substrates that need wall anchors and there are lightweight substrates of foam PVC that will sag in the middle if fixed to the wall with a single fixing in the centre of the sign. Choose a material and make sure that it can be fixed to the surface that it is going to be attached to before you order it.
Budget Against Lifespan
Unless a product is very cheap it is unlikely to save you any money in the long run. All materials have a lifespan and if a cheaper material only lasts for 6 months and you need 2 of them this could cost you more than a better quality product that lasts for 5 years. It is always best to check the British Standards for outdoor sign durability as this will tell you the expected performance and weathering of the material.
