The 4mm Coroplast material measures approximately 0.16 inches thick — strong enough for outdoor durability but still lightweight for easy handling.
PVC signs are solid and rigid, offering a premium finish for long-term indoor use, while Coroplast signs are corrugated, more lightweight, and ideal for short- to mid-term outdoor displays.
When properly installed and maintained, 4mm Coroplast signs can last up to 2 years outdoors without major fading or wear.
Materials like Aluminum Composite Panels or PVC Boards are stronger and more rigid than Coroplast, making them better suited for permanent signage or long-term installations.
Ensure that the file meets the required dimensions for the product. Create the artwork in CMYK color mode at 300 dpi resolution, with a 1/16 inch bleed on all sides to prevent unwanted white edges after trimming.
Embed all images within the file, and convert all text to outlines to avoid font issues during printing.
Export the final design as a PDF with bleeds to ensure accurate printing results.
