Graphics, numbers & frost over security film · an Epic process

Frost it, number it, brand it — without touching the security film.

Every building that installs security film asks the same question a week later: now how do we put the room numbers back? Epic prints frost bands, door and classroom numbers, security decals and graphics on a removable film-safe layer that goes over the installed film — and peels off clean when things change. No residue, no lifted edge, and Epic stands behind the layer and its removal.

The problem

Anything stuck to security film pulls at it on the way off.

The most common way filmed glass gets damaged in a school or an office is not a cleaner — it is a sign. Tape, a laminated notice, a vinyl door number, a security decal: when it comes off, it pulls at the film, and a lifted edge on security film is a service call and a warranty question.

So the industry answer to “can we put the room numbers back?” has always been “no.” That leaves buildings with secured glass and no way to number a door, screen a workstation from the sidewalk, or post the visitor rules — or, worse, with a custodian and a roll of tape.

Epic’s answer

A second layer, made to come off.

We print and apply a film-safe layer on top of the installed security film: a custom-printed frost or privacy band, a printed graphic, door and classroom numbers, security and visitor decals, logos, hours — on a removable-adhesive PET film Epic developed for exactly this. It bonds to the security film without affecting it, holds up to daily use and cleaning, and when the room changes or the sign is retired it peels off clean — no residue, no lifted edge, the security film underneath exactly as we left it, and Epic stands behind the layer and its removal.

It is cut on Epic Precision, printed at VisuFlare, and installed by the same crews that installed the security film.

Every installer who touches the layer is an Epic employee trained in-house on the film-safe process — the same crews that installed the security film under it. What the badge means →

What goes on

Six things buildings put back on the glass — the film-safe way.

Schools · campuses

Classroom & door numbers

Double-sided room numbers that read from the corridor and from the parking lot — what first responders and bus drivers actually need. Cut to the district’s standard.

Government · offices · clinics

Frost & privacy bands

A custom-printed frost band at screen height over the security film: privacy from the sidewalk, daylight above and below, and it lifts off clean if the floor plan changes.

Schools · government

Security & visitor decals

“All visitors must check in,” weapons-free zone, camera notices, compliance decals — updated without re-filming the glass.

Any secured entry

Wayfinding & hours

Entrance IDs, directional arrows, hours of operation, accessibility marks on filmed entries and vestibules.

Schools · retail · corporate

Brand, mascots & color bands

Printed graphics and logos on secured glass — the mascot on the vestibule, the brand band across the storefront — without putting anything in contact with the security film but Epic’s layer.

Schools · public counters

Reusable flyer holders

Holders on the same film-safe media, so a school can post a flyer for a day, a week or a month, take it down and use the holder again. Tape never touches the glass.

The rule on filmed glass

Nothing sticks to the film. Ask us instead.

Once Epic has filmed the glass, the rule is simple and worth putting in the building’s standards: nothing is applied directly to the film by anyone but Epic. Not tape, not vinyl, not a laminated notice. When you need something on the glass, there is a film-safe product for it — send us the list before anyone reaches for the tape.

How it started

Two problems on one pane of glass.

A county government building in Albuquerque, New Mexico needed 3M security film on its street-level glass for forced-entry and blast mitigation — and the workstations behind that glass carried sensitive information on their screens, in full view of the sidewalk. Film alone solves one problem and leaves the other. Epic installed 3M Scotchshield S2400 with the Epic Method, then a custom-printed frost band over it at screen height: privacy from the street, daylight above and below, and a layer that lifts off clean if the floor plan ever changes.

The same process has since numbered every classroom window and entry across a Colorado school district, over the security film — double-sided numbers that read from the corridor and from the parking lot, the district’s security decals in the entry glass, and reusable holders for flyers on the same media.

FAQ

Graphics over security film — questions

Can you put graphics, numbers or frost on top of security film?
Yes — but only with a layer made for it. Ordinary vinyl, tape and laminated notices pull at security film when they come off, and a lifted edge on security film is a warranty problem. Epic prints frost, numbers, decals and graphics on a removable-adhesive PET film we developed for exactly this. It bonds to the installed security film without affecting it and peels off clean when the room changes.
Does putting a graphic over the film void the 3M warranty?
Epic’s film-safe layer is designed and installed so the security film underneath stays exactly as installed — no residue, no lifted edge — and the 3M warranty stays intact. The same cannot be said for tape, vinyl or signs applied by anyone else, which is why the rule on Epic-filmed glass is simple: nothing goes on the film except Epic’s layer.
What happens when a room number or a decal changes?
It is a quick visit, not a film replacement. The old piece peels off clean and the new one goes on. Districts that change room assignments every summer treat it as routine maintenance.
Can the frost band be printed with a logo or a pattern?
Yes. The band is custom-printed, so it can carry a logo, a pattern, a gradient from frost to clear, text, or the district’s colors. It is cut on Epic Precision and printed at VisuFlare, Epic’s sister print studio.
Who installs the graphics layer?
The same Epic Certified Installation Specialists who installed the security film — Epic employees, never subcontractors. They know what is under the graphic and how it was attached, and they are trained on the film-safe layer specifically.
Does it work over solar or decorative film too?
Yes. The layer was developed for security film because that is where a lifted edge matters most, but it applies over any installed 3M film. If you have signage going up on filmed glass of any kind, send us the list before anyone reaches for the tape.
We already have security film from another installer. Can you still do this?
Usually, yes. A Solutions Advisor checks the film and the edges first; if the existing film is sound, Epic’s layer goes over it the same way. If it is not, you will know that before anything is printed.
