What are Ultra Board Signs?

Ultra boards are a lightweight and extremely rigid type of signage, made of a polystyrene foam core with a high-impact plastic surface. This heavy-duty panel is durable, versatile, and holds its shape for many years indoors. Ultra board signs deliver vibrant print quality and work for a wide range of indoor applications. You can use ultra board signs for presentations, retail environments, POP displays, and event signage.

Ultra Board Sign Printing

The material is a polystyrene foam core sandwiched between two sheets of plastic. Known for its bendable but heavy-duty properties, ultra board is great for interior applications. The material comes in all white with two thickness options: 3/16” (0.188”) and ½” (0.5”). We provide high-quality, full-color printing on ultra board sheets with state-of-the-art UV printers.

There are two options for ultra board printing: single-sided and double-sided. Print on one side of the material to mount it on a wall, easel, or other vertical surface. Get graphics on both sides to hang them and maximize your reach with double-sided ultra board printing.

If you are looking for a lighter and more budget-friendly option, foam board printing is a great place to start. For something with even more rigidity and durability, gator board printing is worth checking out.

Reusable and highly portable, making them easy to store and transport.

Cutting Options for Ultra Board Signs

Our design platform offers the following cutting options for ultra board signs:

Square / Rectangle: The default option in our design tool, featuring classic 90° corners.
Rounded: Select this option to have the corners smoothly rounded for a softer look.
Custom Cut: Your sign will be cut to follow the exact outline of your design.
Custom Cut with Border: The sign is cut to match your design’s shape, with an added border around the edges.

Mounting Options for Ultra Board Signs

Direct Mounting: Attach your sign to a wall using command strips. No drilling or hardware required, and they leave no residue when removed.
Free Standing: Use easel backs to place ultra board signs on tables, floors, or countertops for quick and convenient displays.
Hanging: Hang your sign with suction cups or hooks. You can also select drilled holes in the design tool and use zip ties, which work well for both single- and double-sided printing.

Color wasn't as expected, was told it wasn't SquareSigns fault and offered a 25% discount on a reprint (your coupons are often more than that). Not great customer service IMO.

I've had UltraBoard signs from other companies with no problems at all. The sign that I ordered arrived with somewhat jagged edges, and more importantly right in the middle of the sign it looks like something didn't print right and had been touched up with a marker of a slightly different color and sheen. I submitted photos and a complaint to support and weeks later still have no solution. Rather than focusing on the issue with their production quality, they seem to be focused on getting a clear picture of the shipping label even though I provide a pictures of the shipping box from both sides and was very clear that there was absolutely no problem with shipping or packaging The problem was with production.

I own a small business and needed an ultra board sign to show my logo near the entrance. The service at Square Signs was really outstanding. The turnaround time is fair and the product has great quality. Will work with you again!

Hiring this design company was one of the best investments we made for our business. After being burned by 2 different sign-making companies, I didn’t even want to deal with anyone. Thankfully I could tell from the start this place was different. Customer support was very professional and also down to earth. They sent me the mockup of the ultra board signs for a trade show and the design was exactly what I wanted. Product met my expectations. Thank you!

I am definitely satisfied with the ultra board sign i got. The printing color is vibrant and the product itself is very lightweight but strong. It came in the exact shape I need. Looking forward to working with you on my next project.

We just moved to a new office and had many blank walls to decorate. We decided to get decorative and logo signs with our brand colors. I’m happy to share my positive feedback about the service at SquareSigns. Besides being professional, they’re also very responsive in sharing advice and showed us proofs to make sure everything was perfect.

I was slightly concerned that my sign would come out a little off-set, but it was perfect. It far exceeded my expectations. Looks great and thanks for the fast turnaround.
