4mm Coroplast Signs

Run Size

4mm Coroplast Signs are the perfect economical option for any business

With 4mm coroplast signage, your customers can create custom yard signs to meet all of their promotional, directional, and political needs (and beyond). Printed in full color on rigid corrugated plastic with optional grommets, they are versatile enough to be placed indoors and durable enough with UV-cured inks and waterproof durability to be staked outdoors. 

At regular temperatures, oils, solvents, and water have no effect on coroplast which also lends nicely to the endurance of the sign. 

Please Note:

When ordering H-stakes, place your rigid sign order with a width size bigger than the height size and order with vertical flutes.

Be aware that the corrugated flute structure results in a very subtle linear effect (faint lines) on the product's surface. The flutes can be horizontal or vertical but are only compatible with H-stakes in a vertical orientation.

 What type of files should I send to over?

We recommend saving as a PDF file. You may also send the file in the following types: JPG, JPEG, TIF, TIFF, and EPS.

We prefer that you send PDF with embedded or outlined fonts. PDF files are easier to handle and will likely speed up your turn-around. Remember to flatten your files before uploading.

Your designs should always start and finish in CMYK color mode.

Your artwork files should be at 300 dpi.

How should I set up my bleed?

Bleed must extend past the cut-line and will be trimmed from the product during the final cutting phase. When the image is required to extend all the way to the edge, bleed is needed to preserve the finished look and the quality of the final product.

Please keep all text at least 0.125" inside the cut-line.
