Posters and Banners Are Unforgiving
A poster with the wrong colours or a banner that curls in the rain doesn’t just look bad — it undermines whatever you were trying to promote. Unlike a business card someone glances at once, a poster or banner is usually the loudest thing in the room, which means mistakes are very visible.
This guide covers the top 10 print shops in London for posters and banners, from same-day digital posters to weatherproof outdoor signage for exhibitions and events.
Posters vs Banners: What’s the Actual Difference in Production?
It’s worth understanding this before you order, because it changes what to ask for:
- Posters are typically printed on paper or card stock (matte, satin or gloss), in standard sizes from A4 up to A0 or larger. They’re best for indoor display, presentations, retail windows and events.
- Banners are usually printed on PVC, mesh or fabric, designed to be more durable and often used outdoors. Roll-up (pull-up) banners are portable and reusable; PVC banners are typically fixed in place with eyelets for hanging.
- Foamex boards sit somewhere in between — rigid, durable, and good for signage that needs to stand up on its own or be mounted.
Getting this choice wrong is the most common mistake — ordering a paper poster for an outdoor event, for example, when a weatherproof PVC banner was what the job actually needed.
Top 10 Best Print Shops in London for Posters and Banners

How to Choose Between Poster and Banner Materials
- Indoor event or presentation? A satin or matte paper poster is usually sufficient and more affordable.
- Outdoor promotion, more than a day or two? Go for PVC banner material with UV-resistant ink — standard paper posters will not survive rain or direct sun.
- Exhibition or trade show? A roll-up banner is the most practical choice — portable, reusable, and quick to set up between venues.
- Permanent or semi-permanent signage? Foamex board is rigid enough to be mounted or free-standing without warping.
- Replacing a damaged banner before an event? Speed matters more than material choice at that point — go straight to a same-day specialist like Light Print London and call rather than emailing.
Frequently Asked Questions
Can posters and banners be printed the same day in London? Yes, for many standard sizes and materials. Light Print London and a handful of other large-format specialists offer same-day production on selected poster and roller-banner specifications, provided your artwork is submitted before the cut-off time and the job doesn’t require extensive mounting or lamination.
What’s the best material for an outdoor banner in London weather? PVC banner material with UV-resistant, weatherproof ink is the standard choice for outdoor use in the UK, since it holds up against rain and sun far better than paper or standard vinyl. Mesh banners are a good alternative for locations exposed to wind, as they let air pass through.
What size poster should I order for an event? It depends on viewing distance. A3 or A2 works well for close-up display like a shop counter or table. A1 or A0 is better for wall displays or exhibition stands viewed from a few metres away. Light Print London offers all standard sizes plus custom poster sizes if your requirement doesn’t fit the standard range.
Are roll-up banners reusable? Yes, that’s their main advantage over fixed PVC banners. A well-made roll-up banner can be used across multiple events, retracting into its base for easy transport and storage between uses.
What happens if my banner is damaged before an event? Contact a same-day specialist immediately rather than your original supplier if they can’t turn it around in time. Light Print London regularly handles urgent replacement signage and banners delivered straight to a venue when another supplier’s order has gone wrong.
