Reflective Coroplast

A Sign Built to Be Seen After Dark

Sundown is exactly when this sign starts earning its keep. A plain coroplast sign leans on daylight and disappears at night, but this one carries a reflective film across a full-color print, so a headlight or a flashlight makes it glow instead of fade. Marking a parking entrance, staking a listing on a dark street, or posting a detour on an unlit road, reflective coroplast stays legible when a standard sign would vanish. One sign starts at $29, rated 4.9 out of 5 across 61 reviews.

These signs punch above their weight. The 4mm white coroplast is light enough to stake into a lawn yet weatherproof enough to live outdoors, and the reflective film does the night shift for free.

What Are Reflective Coroplast Signs?

Reflective coroplast is a coroplast sign, meaning corrugated plastic, laminated with a reflective film. At 4OVER4.COM it prints full color on 4mm white coroplast in any size, on the front only or both sides, and the film makes the sign visible when light hits it in low-light or nighttime conditions.

Coroplast is the fluted white board you see on yard signs and event signage. It is lightweight, rigid, and weatherproof, so it holds a printed message outdoors without warping or soaking through. The reflective version adds a film across the printed face. In daylight it reads like any full-color sign. After dark, when a headlight or a flashlight beam lands on it, the film bounces that light back so the sign stays legible. If you do not need the night visibility, the Standard Coroplast Signs print on the same board without the reflective film, and this is the version that keeps working after the sun sets.

How Much Do Reflective Coroplast Signs Cost?

Reflective coroplast starts at $29 for one sign, printed to any size you set. You can order 1 to 100 signs, and the live configurator shows the exact total as you choose the size, ink coverage, grommets, and H-stake before you check out.

The entry price is $29 for one sign at the size you enter. A single property marker and a small batch of directional signs both work, up to 100 signs in a run. Printing the back, adding grommets, or planting it on a wire H-stake adjusts the total, and every change shows in real time as you build the sign. Want a proof before it prints?

How Does the Reflective Film Work?

The reflective film bounces light back toward its source, so the sign stays visible at night when vehicle headlights, a flashlight, or a streetlight hit it. It is the same principle used on road and safety signage, applied over a full-color coroplast print.

A standard sign relies on ambient light, which is why an ordinary yard sign fades once the sun goes down. The reflective film changes that. It returns light back toward whoever is shining it, so a driver rolling up with headlights on sees your sign glow instead of disappear. That makes reflective coroplast the pick anywhere a sign has to work at night: a parking entrance, a construction detour, a directional arrow on a dark road, or a real estate sign a buyer drives past in the evening. The full-color print sits under the film, so the message and the visibility come from one piece, with no separate reflective add-on to mount.

What Size Can a Sign Be, and Can You Print Both Sides?

Reflective coroplast prints to any size you set, so the finished sign matches your exact dimensions rather than a fixed preset. Ink prints two ways: 4/0, full color on the front with a blank back, or 4/4, full color on both sides for a message readers see from either direction. All the sizes, ink options, grommet choices, and turnaround are grouped below exactly the way the live configurator presents them, so you know what you can change before you change it.

Size is open here. Instead of picking from a short list of presets, you enter the dimensions you need, from a small directional marker up to a full lawn-sized sign, and the price follows the size. Ink coverage is your other big choice. Go 4/0 for full color on the front with a blank back when the sign faces one way, or 4/4 for full color on both sides when foot or car traffic passes on either side, like a parking lane or a double-sided yard sign. Both options carry the same reflective film across the printed face.
