A3 Correx Board Printing – 4mm Printed A3 Signs

A3 Correx Board Printing

Our A3 Correx boards are printed single sided on 4mm fluted plastic, making them a lightweight, waterproof and cost-effective option for temporary signs, notices, displays and promotional boards.

The A3 size is a practical choice when you need a sign larger than A4 but still compact enough to fit on doors, fences, railings, walls, posts, counters, event routes and temporary display areas. It works well for businesses, event organisers, schools, clubs, construction sites, retail shops, hospitality venues and community groups.

Correx is easy to handle, easy to fix and suitable for indoor or temporary outdoor use. It is commonly used where a standard paper poster is not durable enough and a larger rigid sign board is not required.

Why use A3 Correx instead of a paper poster?

Paper posters are useful for indoor displays, but they can crease, tear or absorb moisture. A3 Correx boards are more rigid, waterproof and easier to fix to fences, railings, walls, posts, doors and temporary display areas.

Choose A3 Correx when you need a compact sign that can be handled, moved, cable-tied or displayed outside in a protected or temporary location.

Flute direction

Correx is a fluted plastic material. The flute direction affects how the board can be fixed, especially if using cable ties, stakes, posts or hanging points.

Choose horizontal flute for many standard signs and wall-mounted displays. Choose vertical flute if the board needs to be fitted to stakes or posts. Choose don’t mind if the flute direction is not important for your use.

Artwork for A3 Correx boards

For best results, supply your artwork as a print-ready PDF at A3 size. We can also accept AI, EPS, JPG and PNG files. Artwork should be high resolution, set up in CMYK colour where possible, and include any bleed required for trimming.

If you are unsure whether your artwork is suitable, upload it with your order and our team will check the file before production.

A3 Correx, A4 Correx or larger signs?

Choose A4 Correx boards if you need small signs for compact notices, labels, information points or close-up display areas.

Choose A3 Correx boards if you need a more visible temporary sign for events, directions, site notices, shop offers or safety information.

Choose larger Correx signs if you need stronger visibility for estate agent boards, roadside signs, car park signs, site boards or outdoor advertising.

Choose poster printing if your display will be indoors, placed in a frame or fixed to a flat surface where a rigid board is not needed.

If you are unsure which option is best, contact our team and we will recommend the most suitable product.
