    Quick tips to print perfection

    Which file types can I use? arrow
    We like to be as flexible as possible, so you can upload your files as PDF, JPEG, TIFF and PNG. PDF's and JPEGs are the most accepted file type across all our products, so we recommend using those wherever possible.
    What is bleed? arrow
    Bleed is an area of print outside the document that must be added to your artwork before it’s sent off for print. By adding the all-important bleed (a minimum of 3mm on all edges), there’ll be no risk of white space left on your document and it'll be trimmed correctly without cutting into any design. Some products require a different amount of bleed, so be sure to check our downloadable templates to find out the correct amount.
    What is safe area? arrow
    The safe area is the space inside where your print will be trimmed. Keeping any important parts of your design away from this area will make sure that they aren’t accidentally trimmed off due to the natural movement while your print gets finished. Our downloadable templates will indicate the recommended amount of safe area for your print.
    What’s the difference between RGB and CMYK? arrow
    ​​RGB is the colour gamut used to display images on a computer screen, and stands for Red, Green and Blue. CMYK is the colour gamut used for conventional printing, and stands for Cyan, Magenta, Yellow and Black. Unless you’re printing Gicée Fine Art Prints, Photographic Prints or Mugs, please set up your artwork in CMYK.
    What are Versions? arrow
    Our Versions service lets you print multiple designs using the same product specifications. For instance, if you have five different designs that share the same size, orientation, and paper stock, you can print them all at once using this service. By opting for Versions, you're increasing your overall quantity, which means you'll enjoy a lower cost per unit. To use Versions, simply select "yes" in the product builder when prompted with "Do you want to print more than one design?". When using Versions, the quantity you enter in the product builder applies to each design. For example, if you choose a quantity of 10 with 5 Versions, you'll receive a total of 50 prints.
    What is personalisation? arrow
    Personalisation is a simple, cost-effective way to tailor each of your individual prints. You can use personalisation for different text elements like names, addresses, and even personalised messages. However, if the text content on your design is the same for all prints, you don't need personalisation. There are two main options for personalising your print - you can either choose to add the personalised elements to your artwork yourself, or send us your artwork with a placeholder and a CSV containing a list of all the names/ personalised elements, and we’ll merge the two for you.
    Why do I need to embed fonts? arrow
    If you don’t embed fonts and your document is opened on another computer system that doesn’t have access to the original fonts, different fonts will be substituted instead. This could really affect the look of your finished print. Embedding fonts into your original design will stop them from changing.
    Everything you need to know about resolution arrow
    Remember to save your artwork out at a minimum of 300dpi resolution. This will ensure that when printed, your artwork quality is as crisp as possible.

    What is the difference between Correx and Foamex?

    Correx and Foamex are two popular materials for signs, but they’re designed for different needs.


    • Correx is a lightweight, corrugated plastic that’s perfect for temporary signs like estate agent boards or event displays. It’s cost-effective, weather-resistant, and a great option for short periods.
    • Foamex, on the other hand, is made from sturdy PVC. It’s more durable and ideal for high-quality prints or signage that needs to last, whether indoors or outdoors.
    Both options have their strengths, so the choice depends on what you need your sign to do!

    Are Correx Signs waterproof?

    Yes, Correx signs are waterproof, making them a great choice for outdoor use. Their sturdy corrugated plastic design means they can handle light rain and damp conditions with ease. However, if the signs will be exposed to heavy rain or harsh weather for long periods, you might want to consider a more durable option like Foamex. We're here to help you find the right fit for your needs!

    What is Correx made from?

    Correx is made from two strong sheets of PVC-free polypropylene, a strong yet lightweight type of corrugated plastic. It’s durable, flexible, and resistant to weather, making it a practical choice for a variety of uses. Plus, it’s recyclable, so you can count on it being an environmentally friendly option too.

    Can I print double-sided on my Correx Board?

    Absolutely! Correx Signs are designed for double-sided printing, making your designs pop on both sides. They’re lightweight, durable, and perfect for outdoor signage or promotional displays that need visibility from every angle.

    What are Versions?

    Our Versions service allows you to print more than one design with the same product specification. For example, if you have five different Correx Board designs all on the same size and orientation, you can use Versions to print them all in one go. Using Versions means that you're printing a higher quantity and therefore will benefit from a lower unit cost.


    To use Versions just choose "yes" in the product builder when asked "Do you want to print more than one design?". If you're using Versions, the quantity you choose in the product builder is per Version. For example, choosing a quantity of 2 and 5 Versions means you'll receive 10 Correx Boards in total.
