Coroplast Printing Collection

Coroplast Signs on 4mm Corrugated Plastic

Coroplast printing puts full color on 4mm white corrugated plastic, one side or both, from $25 for a single sign. Standard sizes run 11 by 17 to 30 by 40 inches, yard signs come at 12 by 18, 12 by 24 or 18 by 24 inches with an optional H-stake, and any size is an option. The same sheet works on a lawn in the rain and in a lobby.

This collection pulls together five coroplast options, from Standard Coroplast Signs and Coroplast Yard Signs to Dry Erase Coroplast and Reflective Coroplast. 4OVER4.COM has printed for more than 150,000 businesses since 1999,

Five Coroplast Signs and Which One Fits

All five print on the same 4mm white sheet, one or both sides, with grommets at the top corners or all four.

What Makes Coroplast the Right Sign Material

Coroplast is a brand name for corrugated plastic sheeting, technically twin-wall polypropylene. It works like a plastic version of cardboard that stays flat when it gets wet. Those internal flutes make each sheet stiff and rigid while keeping the weight low, which is exactly why you see it on lawns, at construction sites, and in store windows everywhere.

The material resists moisture, chemicals, and UV on its own. A printed coroplast sign can sit through rain, snow, and full sun without warping, fading, or peeling.

Aluminum lasts longer but costs more and weighs a lot more. Foam board looks clean indoors but dissolves in the rain. For temporary and semi-permanent signage where budget matters, corrugated plastic is usually the lower-cost choice.

Where Coroplast Signs Earn Their Keep

A real estate agent can print open house signs, directional arrows and For Sale panels on both faces, so one sign covers both directions of traffic. A political campaign can hand out Coroplast Yard Signs that volunteers carry easily, and the fluted channels accept standard H-wire stakes, so setup takes seconds.

A retailer or event planner can use coroplast for grand openings, sidewalk sales and festival wayfinding, then swap the artwork each season. A contractor can zip-tie job-site and safety signs to fences.

Design Choices That Make Coroplast Read Well

A strong coroplast sign starts with a few smart calls before you upload artwork. Most of these signs get read from a distance, so keep your headline text large, roughly three inches tall for every 25 feet of viewing distance, and cut the fine print. If it isn't clear at a glance, it isn't working.

Contrast does the heavy lifting outdoors. Dark type on a light background, or the reverse, reads best, while combinations like red on orange or yellow on white blur together from across a parking lot. Bold, saturated colors print beautifully on coroplast's smooth white surface.

Match the product to the job and you'll get better results. Dry Erase Coroplast suits menus and schedules that change often, while Plastic Coroplast Signs give you the classic outdoor durability people expect. For a die-cut shape or an odd dimension, our custom project option opens up sizes well beyond the standard rectangle.

How Ink Gets Onto a Coroplast Sheet

Corrugated plastic does not take ink the way paper does. The surface is non porous, so the two processes that work both bond the ink on top instead of letting it soak in.

Flatbed digital printing lays UV ink straight onto the sheet and cures it under lamps in the same pass. It handles photographs, gradients, and a different design on every sign in a run, which is what makes short runs and one off signs affordable. Screen printing pushes thick ink through a stencil one color at a time. Setup takes longer and every color needs its own screen, so it only pays off on long runs of a simple two or three color design.

Either way the ink sits on a plastic face, so durability comes from the cure rather than from the stock.

Flute Direction and How the Sign Gets Mounted

Every coroplast sheet has hollow channels running one way through it, and which way they run decides how the sign mounts. Vertical flutes let an H stake slide up inside the sheet, which is the standard for lawns and roadsides. Horizontal flutes make the sheet stiffer across a long span, which suits a sign that hangs on a fence or bolts to a frame.

For fence mounting, plan grommets or zip ties at the corners and hold artwork a half inch clear of the holes. On an open lawn, two stakes hold a wide sign far better than one.

Double sided printing earns its keep wherever people pass from both directions, which suits open house arrows.

Can you print directly on Coroplast?

Yes. Flatbed UV printers put ink straight onto the sheet and cure it on contact, so a standard sign needs no separate vinyl layer. Direct printing also keeps the corners clean, since there is no laminate to lift after a few weeks of weather.

How much does Coroplast cost?

The final price moves with size, quantity, and whether the sign prints on one face or both. Larger runs bring the cost per sign down, which is why campaign and multi location orders land lowest.
