About A3 Posters 170gsm
Product specifications sourced from our UK print partners.
Don’t worry if you’re not sure about your artwork
We check every file before it goes to print. If we spot something that could affect the finished result, we’ll review it and help you get it sorted wherever we can. We won’t send artwork to production if we think there’s a problem.
For the best print result, please prepare your file using these product-specific guidelines:
- Supply a print-ready PDF in CMYK with all fonts outlined or embedded
- Build at the finished size with 3mm bleed on every edge
- Keep text and logos 10mm inside the trim
- 150 DPI at final size is fine for posters viewed from a distance; use 300 DPI for A3 and smaller
- Avoid enlarging web images — check the physical size with our print size estimator first
- RGB files are converted to CMYK for press, which can shift bright blues, greens and oranges
Not sure if your file is suitable? Send it anyway — we’ll check it before production.

A3 Posters 170gsm buying guide
Written by our studio team — what to choose, and what usually goes wrong.
- Both are 170gsm coated paper. Silk has a soft sheen that reduces glare under shop lighting; gloss makes photos look more vivid.
- Posters are paper, not weatherproof — for outdoor or long-term sun exposure, plan to replace them.
