A3 poster printing has consistently proven to be a powerful and efficient means of conveying information to an audience. A3 posters are the ideal solution for promoting events, sales, and products, as well as serving as attention-grabbing signage for trade shows and other occasions.

Their size strikes a perfect balance, making them perfect for indoor or outdoor advertising.

A3 posters are a popular choice for advertising products, services, events, or promotions. They can be prominently displayed in storefronts, on community bulletin boards, in public areas, or distributed to inform potential customers about special offers. A3 posters also make a visually appealing canvas for motivational quotes, affirmations, or inspirational messages. They can serve as daily reminders of goals, aspirations, or positive affirmations, adding a touch of inspiration to any space.

Creating an impactful A3 poster is a blend of creativity, visual allure, and concise communication. Begin by establishing a clear objective for your poster.

  • To design my A3 poster, how to I define its category?

    There are too many poster categories to list, however we’ll discuss the 3 most popular types.

    Promotional Posters
    Promotional posters keep to the theme of advertising product and service. For example promoting events like clearance sales, fun fairs or gigs.

    Educational Posters
    Educational posters generally have more content in the form of text. This is mainly because it is meant for a closer read.

    Motivational Posters
    Motivational posters will usually have a low to moderate balance of text and imagery. The idea is to keep the message clear without over complicating the design.

  • What makes a good A3 poster design?

    Posters are usually viewed at a distance of just over a metre. It is therefore important to make your messages clear and concise.

    We recommend making the text on your A3 poster bold, clear and attractive. Choose a font type that works with the overall paper dimension. Nothing too small or too big, keeping readability in mind at all times.

  • How do I choose the content for my A3 poster?

    For the best outcome we recommend assessing your business in detail. For example your industry type and the products and services it offers. Is it suitable for both genders? The age of your target audience? It is worth considering where you’ll want to display your posters. Maybe in shop windows? In notice boards? Along hallways? Or outdoors inside snap frames.

  • Do you print A3 waterproof posters?

    Yes! Our 550gsm PVC vinyl media is tear-resistant and waterproof. Meaning there is no need to put these posters inside protective snap frames. The media surface can also be wiped clean with a damp cloth if the print gets dirty.

  • How do you print your A3 posters?

    Our A3 posters are printed in full colour using a CMYK process. We use a combination of digital and lithographic techniques to achieve the best results and prices.

  • What is CMYK?

    CMYK is an acronym for cyan, magenta, yellow and black. These are the colours used in the printing process of your A3 posters.
