  • What makes a good poster design?

    Posters are usually viewed at a distance of just over a metre, so it is important to make your messages clear and concise. The temptation to completely fill all white spaces should be avoided. Posters are impulsive marketing tools and designed to achieve immediate results.

  • How many types of posters are there?

    There are too many poster types to list but generally speaking there are 3 popular types. The first being promotional posters. These posters keep to the theme of heavily promoting the bottom line message for example event and gig posters. The second being educational posters. These posters include more text content and are meant for a closer read. The third being communicational posters. These posters generally include clear messages for the reader, for example motivational posters.

  • How do I choose the content for my poster?

    There a lot of factors to take into consideration before submitting your design for printing. Asses your business products and services, the gender and age group of your target audience and where you’re likely to display your posters.

A3 Indoor & Outdoor Poster Printing by Cheap as Prints

A3 posters are a great all-rounder and suitable for all promotional and advertising displays. Measuring 297 x 420mm these posters are big enough for including a moderate consistency of images, text and colour. For indoor displays, we offer A3 posters on lightweight 170gsm to heavier 250gsm silk stock. For added depth and colour to your design, we are able to laminate your A3 poster. The lamination option is only available in gloss and on our 250gsm silk stock. Laminated posters can be used for outdoor purposes but we’d recommend printing on our 550gsm PVC media. This media has water-resistant properties making it more durable and longer lasting. All our A3 posters are printed in stunning full colour using digital and lithographic printing techniques. This means you can order as little as 1 or hundreds knowing there is no set up to pay. With the right blend of content and white space, A3 posters can be highly effective and help your business achieve maximise results. Simply send us your A3 poster design or let our professional designers help. Our artwork rates are competitively priced and we can send you a design draft within 2 days. If you still wish to provide your own design you can download our free A3 poster design template to be sure your artwork meets printing requirements.
