FAQs
Frequently Asked Questions
Can I get A3 posters printed the same day in London?
Yes — place your order before 2 PM Monday to Friday and collect your A3 posters the same day from our print studio in Finchley, North London.
What file format should I send my artwork in?
We recommend a print-ready PDF with a 3mm bleed on all sides, CMYK colour mode, and a minimum resolution of 300dpi. Download our A3 template above for the correct dimensions.
Which material should I choose for my A3 poster?
For indoor displays, 200gsm Photo Satin or 180gsm Premium Matt are the most popular choices. For vibrant photographic work, 200gsm Photo Gloss delivers bold results. For waterproof or outdoor use, choose from our HP Latex range — Grey Back, Self-Adhesive Vinyl, or 440gsm PVC.
Are your A3 posters waterproof?
Our paper-based stocks (Photo Satin, Gloss, Matt) are suitable for indoor use only. For waterproof and outdoor-rated options, choose 320 Mic Grey Back, Self-Adhesive Vinyl, or 440gsm PVC — all printed on our HP Latex 360.
Can I print A3 posters in landscape orientation?
Yes — we print A3 in both portrait (297 × 420mm) and landscape (420 × 297mm) orientations. If you need landscape, simply set up your artwork at the correct dimensions and we’ll print it accordingly.
