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.

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.

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.

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.

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.

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.




- 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.
