Exhibit-Quality Detail with Field-Ready Durability

An interpretive panel is read from about three feet away, by a visitor standing still for less than a minute, and then it stays in place for the next 30 years. At a trail overlook, outside a primate habitat, in a monument plaza, along a historic district streetscape, or in a museum courtyard, the failure mode is the same, and it is almost never the frame. It is the graphic. Printed laminates chalk and lift at the edges, fiberglass embedments yellow under UV, and text set for arm's-length reading goes milky within a few seasons. Porcelain enamel puts the image inside glass fired over 1400°F, so the graphic ages at the rate of the glass rather than the rate of the ink. That carries a 25-year warranty against fading, discoloration, and gloss reduction from UV exposure, backed by installations performing beyond 30 years in the field.

Our interpretive panels and exhibit frames are installed at National Park Service sites including Yellowstone, Yosemite, Mount Rushmore, and Dry Tortugas, at the Presidio and the USS Arizona Memorial, and at the Smithsonian, the White House, the Getty, and the Newseum. Cultural and science institutions carry the same construction, among them the California Academy of Sciences, the Los Angeles Zoo, Gumbo Limbo, and the United States Holocaust Memorial Museum, as do the East Lake Sammamish Trail and the Phillip Raine Rest Area. We are members of the National Association for Interpretation and American Trails.

Interpretive work arrives at three different scales, and they are three different conversations. All of them start the same way.

The difficult part of a 150-panel program is not the 150th panel. It is making the 150th panel match the third one after 14 months, a design revision, and two funding phases. Color is proofed in our own color lab against an approved standard before the program begins, and every subsequent firing runs against that same standard, so a panel installed in phase three reads as part of the same exhibit as phase one. Panel geometry, frame profile, and finish are held the same way. For large programs we schedule fabrication and shipping in the phases your installation crew actually works in, rather than delivering 200 panels to a maintenance yard at once.

There is no stock catalogue here. Every panel is fabricated to the dimensions on your exhibit plan, which means a low-profile base gets sized to the drawing instead of the drawing getting resized to fit a stock panel. Five mounting families cover most interpretation, indoors and out.

Frame profiles, posts, pedestals, and mounting hardware are a separate decision from the panel itself. Those are covered under frames and mounting systems, including self-supporting stands that need no wall substrate.

A wayside is read standing up, often in direct sun, by someone who has already decided how much time to give it. Interpretive planners generally hold a single panel to a few hundred words, with one dominant image and an obvious entry point, because the visitor reads the title, then the picture, then perhaps two sentences. Set type for the distance the panel is actually read at, not the distance you review the proof at.

Porcelain enamel matters here for two reasons. Contrast holds, so a panel is as legible in year 20 as it was on the day it was set. And the surface can be finished matte, which kills the specular glare that makes a glossy panel unreadable when the sun is behind the visitor. We image at 300 LPI, which holds fine serif type, halftone photographs, and hairline map linework without breaking up. In high-touch settings, zoo rails and children's exhibits in particular, the non-porous fired surface takes handprints, sunscreen, and graffiti removal without hazing, because there is no laminate or coating to strip.

Where an exhibit is meant to be touched, or sits within a required reach range, the 2010 ADA Standards govern: 15 inches minimum and 48 inches maximum above the finished surface for both forward and side reach, over a clear floor space of 30 by 48 inches. In practice that sets the base height and tilt angle of a low-profile wayside more than any other constraint, because the top edge has to stay inside the range while the reading surface stays comfortable for a standing visitor. Where the audience is largely children, exhibit planners often specify a second panel at a lower height, and the reach range still governs anything tactile. Tactile typography and raised elements are fired into the porcelain surface rather than applied to it.

Federal park interpretation follows UniGuide, the unified sign standard that governs panel formats, frame profiles, color, and typography across the National Park Service. We fabricate to the low-profile wayside formats and frame geometries UniGuide specifies, and offer NPS-compliant framing, in porcelain enamel rather than the printed materials often supplied against the same drawings. Museums, zoos, aquariums, universities, and municipal historic districts usually work to their own graphic standard or to an exhibit designer's package instead. Send the standard, the spec section, or the design intent drawings, and we fabricate to them. For a fuller walkthrough of what a federal standard asks for, read our guide to NPS interpretive signage standards.

A 200-panel museum campus program and a single replacement marker for a county historical society start at the same place, and the intake is deliberately short.

1. Send whatever you have. A sketch, a site photo, a panel count, a spec section, or a finished interpretive plan all work as a starting point.
2. We return a quote within three business days, itemized so it can go straight into a grant application, a board packet, or a procurement file.
3. Artwork comes to us as layered files against our file preparation requirements, or we work directly from your exhibit designer's package.
4. We proof color in our own color lab, fire, frame, and ship complete or in phases, fabricated end-to-end in Tumwater, Washington.

Grant-funded and donor-funded projects usually need the number before the money exists. Ask for the quote early, and ask for it in the format your funder requires, whether that is a per-panel unit cost, a not-to-exceed figure for a phased program, or a line-item breakdown with framing priced separately. We would rather write it twice than have you rebuild a budget after award.

Interpretive panels are one part of a larger sign program. Entrance signs, regulatory panels, and trail markers are covered under parks and recreation signage, habitat and species labeling under zoo and aquarium signage, and dedications and named tributes under memorial and commemorative panels.
