FAQs

Poster FAQs

Last updated

What poster sizes are available?

instantprint offers poster printing in eight sizes: A4, A3, A2, A1, A0, 20" x 30", 40" x 30" and 60" x 40". Smaller posters are ideal for notices, menus and shop displays, while larger formats suit exhibitions, events and promotional advertising.

Which poster paper or material should I choose?

The best poster paper depends on how long you plan to display it and where it will be used.

150gsm Silk is a lightweight option for short-term indoor posters, such as temporary promotions, event notices and short campaigns.

250gsm Silk is thicker and sturdier, making it a better choice for posters that need to withstand more handling or remain on display for longer.

For outdoor use or displays exposed to moisture, choose waterproof PVC. It is durable, tear-resistant and wipeable.

What is the difference between silk and waterproof PVC posters?

Silk posters use smooth, coated paper and are best suited to indoor use. Waterproof PVC posters are made from a more durable, moisture-resistant material that can be wiped clean and used outdoors.

Are waterproof posters suitable for outdoor use?

Can I order custom-sized posters?

Can I print multiple poster designs in one order?

Can I print on both sides of my poster?

How should I set up my artwork for poster printing?

Set up your design at the chosen finished poster size and use high-resolution images, ideally 300dpi at print size. Add 3mm bleed around the edges, keep important text and logos at least 3mm inside the trim line, use CMYK colours and supply a print-ready PDF with fonts outlined or embedded.

What is a backlit poster?

Unlike standard posters, they're printed on a translucent 205mic Coala Backlit S film with a matt finish, allowing light to pass through the material and make colours and designs stand out. They're ideal for eye-catching retail displays, illuminated menus, advertising and promotional signage.

Setting Up Your A4 Poster Artwork

Set up your A4 poster artwork at 210mm wide × 297mm high. Add 3mm bleed around every edge to allow your design to print right to the edge after trimming.

Bleed and Safe Zone

Extend background colours, images and design elements into the 3mm bleed area to avoid unwanted white edges after trimming.

Keep important text, logos and other essential details at least 3mm inside the finished edges. This is your safe zone and helps prevent important content from being cut off.

Supplying Your Artwork

Supply your poster artwork as a print-ready PDF using CMYK colours, 300dpi images and outlined or embedded fonts. Make sure your design is set up at the correct dimensions with the required bleed and safe zone.

Once you've selected your poster specifications, add your product to the basket and upload your artwork through our proofing tool. Review and approve your design for print before completing checkout.

If you encounter any issues with your artwork that you can't resolve online, chat with our team for a quick resolution.
