Project context: a busy Memorial Day installation
Lauren at Juniper Cafe needed a blade sign with real presence: bright, round, readable from the sidewalk, and visually consistent with the cafe.
We installed it on Monday, May 26, 2025, during a busy Memorial Day service. The customer line and active sidewalk made staging, ladder placement, pedestrian awareness, and clear crew communication especially important.
The job was straightforward on paper: install a custom illuminated blade sign face about 16 feet above the sidewalk. In practice, the active storefront required disciplined ladder placement, spotters, controlled staging, and steady coordination among the crew.

How we made the Juniper lightbox blade sign face
The sign face started as custom-cut sign white plexiglass. We used our Mars 130 laser cutter to cut a precise circle. For a round lightbox blade sign, a clean edge and accurate fit are especially visible once the cabinet is illuminated.
We produced the graphics as UV printed translucent vinyl and installed the vinyl onto the plexiglass faces. Regular opaque vinyl can look good in daylight but block too much light at night. Translucent vinyl preserves the bright blue, green, and lavender artwork while allowing the lightbox to illuminate the face.
The result was a custom lightbox sign face designed to read from the sidewalk, photograph clearly, and fit the cafe's visual identity. We quote similar fabrication for acrylic signs, illuminated signage, and storefront projects that combine printing, cutting, and installation.
The 16-foot installation: ladders, spotters, and site control
Blade sign installation depends on a quiet checklist behind the finished result: ladder angle, footing, spotter position, tool staging, public sidewalk awareness, hardware, wind, and pedestrian movement around the work zone.
Safety came first. We used extension ladders, kept ground support active, used appropriate fall protection for the site, and controlled the sign face as it moved into the lightbox.
The active storefront required continuous crew communication so customers could move through the area while the sign face was aligned and fastened.
Common questions about custom blade signs
What is a blade sign?
A blade sign is a sign that projects perpendicular from a building, so pedestrians can see it while walking down the sidewalk. For cafes, bakeries, restaurants, boutiques, salons, and small shops, a blade sign is often more useful than a flat wall sign because it catches side-approach foot traffic.
Why was Juniper's sign face made from white plexiglass?
White plexiglass, often called white acrylic, is a common lightbox face material because it diffuses light and gives the printed graphic a clean backing. For Juniper, it also gave us a precise round substrate that could hold the translucent vinyl artwork and sit cleanly in the blade sign cabinet.
Why use UV printed translucent vinyl instead of just painting it?
UV printed translucent vinyl supports detailed color, crisp artwork, and light transmission. Paint can suit other applications, but a graphic lightbox face often benefits from the repeatability and illumination characteristics of printed translucent vinyl.
Can you make this kind of sign for another cafe?
Yes. We can quote fabrication and project-specific installation for San Jose and the listed Silicon Valley service areas. Start with the sign location, approximate size, whether it lights up, and photos of the building. Our project form is the easiest place to send that.
Do you handle the installation too?
Installation is quoted for San Jose and the listed Silicon Valley service areas. The written scope confirms access, equipment, mounting, approvals, and crew responsibilities before scheduling.
Need a custom blade sign or illuminated storefront sign?
Send the building photos, logo, approximate dimensions, lighting details, and known site constraints. We can review the fabrication and installation requirements for a readable sidewalk sign.
