Foam Core & Ultra Board Signs

Lightweight rigidity meets high-resolution printing. Perfect for corporate presentations, retail displays, and short-term event branding.

Foam Core & Ultra Board Signs

When you need temporary signage that still looks premium, standard poster paper won't cut it. Foam core provides a rigid, flat surface that won't curl on an easel or warp in a frame. SignForge prints directly onto high-density foam boards using UV-cured inks for stunning, photographic quality. For applications requiring more durability, we step up to Ultra Board—a heavy-duty foam core with plastic faces that resists denting and bending.

Fabrication

How we build it.

Five disciplines under one roof — engineered metalwork, digital precision, and hand craftsmanship.

  1. Welder fabricating a steel sign frame

    01

    Structural Metal Fabrication

    Heavy-gauge steel and aluminum are cut, welded, and reinforced in-house to engineered specs. Every frame is built to withstand decades of wind load, seismic movement, and coastal weather.

  2. MultiCam CNC router carving wooden sign panels

    02

    Precision CNC Machining

    Automated multi-axis CNC routers carve intricate 3D profiles from thick wood, PVC, and composite stock with sub-millimeter accuracy. The result is repeatable, dimensional detail that hand tooling can't match.

  3. Fiber laser cutting precision metal sign components

    03

    Advanced Laser Cutting

    High-powered lasers slice acrylic and plastic with flame-polished, ready-to-finish edges, and cut thin metals to tight tolerances. Every letter, logo, and inlay assembles cleanly the first time.

  4. Large-format Roland printer producing a vinyl banner

    04

    Large-Format Digital Printing

    Commercial-grade flatbed and roll printers produce vivid, UV-stable graphics on substrates up to monument scale. Inks and laminates are rated for years of outdoor exposure without fading or peeling.

  5. Craftsman hand-finishing dimensional letters

    05

    Artisan Hand-Finishing

    Master craftsmen complete every piece by hand — custom color matching, fine detail painting, and meticulous finishing. It's the final layer that separates a manufactured sign from a signature one.

FAQ

Common questions.

Channel letter installation on storefront
Project manager reviewing site plans
Finished interior lobby signage
Fabricator measuring channel letter depth
Can foam core signs be used outside?
Standard foam core is strictly for indoor use as the paper faces will warp if exposed to moisture. However, we offer corrugated plastic (Coroplast) as an inexpensive outdoor alternative.
Do you print directly on the board or mount a poster to it?
We print *directly* onto the board using flatbed UV printers. This eliminates the risk of peeling or bubbling that happens with mounted paper posters.
What is the maximum size for a foam board sign?
We print on full 4x8-foot sheets in a single, seamless piece.
