Whether you are running a bustling cafe in the heart of Tavistock or preparing for a national trade show, the way you present your information matters. At ABC Service, we believe that signage shouldn’t just be functional, it should be a reflection of your brand’s quality. That is where our A3 boards and signs come in.
Measuring 297x420mm, A3 is often called the "Goldilocks" size of the printing world. It is large enough to be seen from across a room but compact enough to fit comfortably in window displays, on countertops, or as part of a larger exhibition stand. But choosing the right size is only half the battle; choosing the right material is what ensures your message stays looking sharp for years to come.
In this guide, we’ll dive into why A3 rigid signs are a fantastic choice for your business and how our in-house experts in Devon bring them to life.
Why Choose A3 for Your Signage?
When you’re looking at signage options, it is easy to get overwhelmed by the range of sizes. Why pick A3 over, say, the smaller A4 boards or the larger A2 signs?
The beauty of A3 is its versatility. It provides enough surface area for high-resolution graphics and readable text without requiring heavy-duty mounting hardware. It’s the perfect canvas for:
- Menu Boards: Large enough for a full list of specials but small enough to be swapped out daily.
- Point of Sale (POS) Displays: Perfect for "New Arrival" or "Limited Offer" signs near the till.
- Event Wayfinding: Helping guests find the "Registration Desk" or "Toilets" at local events.
- Safety Notices: Essential for office environments where clear, rigid instructions are needed.
Breaking Down the Materials, Foamex vs Dibond
At ABC Service, we don't believe in a one-size-fits-all approach. We offer three primary materials for our A3 boards, each suited to different environments and budgets.
1. 3mm and 5mm Foamex (PVC Foam Board)
Foamex is our most popular choice for indoor displays. Despite the name, it isn't "foamy" or soft; it is a rigid, lightweight PVC board with a smooth, matte finish.
- 3mm Foamex: Ideal for internal signage, directional signs, and exhibition graphics. It is incredibly light, making it easy to fix to walls using simple adhesive strips or Velcro.
- 5mm Foamex: Offers that extra bit of "heft." It’s more robust and less prone to flexing, making it excellent for standalone easel displays or busier retail environments.
A3 foamex board printing is a brilliant, cost-effective way to get high-impact visuals without a massive price tag.
2. 3mm Dibond Metal (Aluminium Composite)
If you need something that can handle the unpredictable Devon weather, A3 dibond printing uk is the way to go. Dibond consists of two thin sheets of aluminium bonded to a solid polyethylene core.
- Weather Resistance: It won’t warp in the sun, crack in the frost, or rust in the rain.
- Durability: It is extremely rigid and impact-resistant. This is the material we recommend for permanent outdoor shop signs, parking notices, or long-term external branding.

The ABC Service Difference, 8-Colour Precision in Tavistock
A sign is only as good as the print on top of it. While some "faceless" online printers use 4-colour systems that can leave photos looking flat or grainy, we do things differently.
We utilise an 8-colour wide format printing process right here in our Tavistock workshop. This includes specialised inks (including white!) that allow for a wider colour gamut and smoother gradients. This means your brand colours will be "spot on," and your images will have a depth and vibrancy that truly stands out.
Because we print everything in-house, we have total control over the quality. Our team checks every board for crispness and colour accuracy before it ever leaves our desk. Whether you need foamex printing tavistock for a local project or you're ordering from the other side of the UK, you get that same level of care.
"We take pride in our 'non-call-centre' approach. When you call us about your signs, you’re talking to the same people who will be operating the printer. It ensures nothing gets lost in translation." , Brett, Director
Applications that Pop
Not sure how to use your A3 boards? Here are a few ways our clients are currently using them to grow their businesses:
Retail Window Displays
An A3 board is the perfect size for a window display. It doesn't block the light or the view into your shop, but it provides a clear focal point for passers-by. Pair it with a high-quality finish, and you’ve got a professional look that beats a paper poster any day.
Exhibition Stands
When you're at a trade show, space is at a premium. Using a series of A3 boards allows you to create a modular information wall. You can move them around, swap them out for different days of the event, and transport them easily without needing a van.
Restaurant and Cafe Menus
Nothing looks better than a well-designed menu on a rigid board. It feels more premium than a laminated sheet and stays flat on an easel or mounted on the wall. Plus, our prints are wipeable, making them perfect for busy hospitality environments.

Responsible Printing for a Better Future
As a "Responsible Local Partner," we are deeply committed to the environment. We know that the printing industry can be heavy on resources, which is why we’ve taken steps to give back.
Our media is Carbon Captured. Through our partnership with the Woodland Trust, we help fund the planting of new native woodlands right here in the UK. This helps offset the carbon footprint of the materials we use. When you choose ABC Service for your A3 boards and signs, you aren’t just getting a first-class product, you’re supporting sustainable business practices that benefit our local community and beyond.
How to Get Your A3 Signs Just Right
Ordering is simple, but there are a few things to keep in mind to ensure your signs look their best:
- Resolution is Key: Ensure your artwork is at least 300dpi. Since A3 is often viewed up close, any pixelation will show.
- Bleed Matters: Add a 3mm bleed to your designs to ensure no white edges appear after the boards are cut to size.
- Choose Your Finish: We offer gloss or matte lamination to add an extra layer of protection and change the "feel" of your sign.
- Rounded Corners: Want a softer, more modern look? We can round the corners of your boards for a small additional fee.
If you aren't a design wizard, don't worry! Our Graphic Design service is here to help. We can take your logo and ideas and turn them into a professional, print-ready layout.

Frequently Asked Questions
Can I use Foamex signs outside?
Yes, you can! Foamex is weatherproof, but it is better suited for short-to-medium-term outdoor use (up to 2 years). For permanent outdoor signage, we always recommend Dibond.
Do you offer double-sided printing?
Absolutely. We can print on both sides of our Foamex and Dibond boards, which is great for hanging signs or pavement displays where customers are approaching from both directions.
How quickly can I get my A3 boards?
Our standard turnaround is 4-6 working days, but if you're in a rush, we offer a 2-3 working day express service.
