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 Giclée Fine Art Prints or Photographic Prints, 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.
Where can I find templates for shapes? arrow
If you've chosen a shape for your print (such as arch, wavy, circle or pebble where available), you'll find templates for these shapes on additional layers within the standard square or rectangular template. Download the template for the correct size, then delete the layers you don't need, leaving the layer for your chosen shape as a guide while creating your artwork. Delete all template layers before saving and uploading your artwork. This will prevent the template from being printed on top of your design.

What should I know before preparing artwork for print?

Here are the 7 key things you need to know before preparing your artwork to be printed with us:

1. We provide downloadable templates:
On most of our product pages, you can find free downloadable templates to help you set up your artwork for print. They’re available in AI, IDML and PDF formats to suit the design software you’re working in. Our downloadable templates include key information on creating artwork as well as instructions on how to save out your print-ready PDF. 

2. You need to include bleed:
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. 

3. Keep in mind the safe area:
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. 

4. The difference between RGB and CMYK:
​​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 Giclée Fine Art Prints or Photographic Prints, please set up your artwork in CMYK. 

5. Embed your fonts:
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. Find out how to embed your fonts here.

6. Check your image resolution:
For the best print results, all artwork files should be at least 300dpi (dots per inch) when saved at the actual size they will appear in your design. This ensures that your final printed project is sharp and clear, not blurry or pixelated.

7. How to export a PDF:
Exporting your design into a print-ready PDF is easy. We’ve created some handy video guides which will take you through the process which you can find here.

Find lots more artwork tips here, including if you’re printing any special finishes such as foiling. For products with multiple pages, such as Brochures or Booklets, explore our book printing guide here. 

What is a Professional File Check?

For a small fee, an expert member of our technical team will manually review your artwork before it goes to print so you can press 'go' with complete confidence. 


If you've ordered multiple products, you can choose to add a Professional File Check to individual jobs or your entire order. We'll check your file for common print setup issues and, where possible, fix them before production. If we find anything that needs your attention, we'll contact you and place your order on hold until you've updated and re-uploaded your artwork. 

We'll check things like: 
  • Image resolution for print quality 
  • Bleed and safe areas 
  • Page count and page order on folded products
  • Corrupt, blank or password-protected files 
  • Templates left on artwork 
  • Folds, cut lines, drill holes and binding areas (where applicable) 
  • Foil alignment and minimum line widths (where applicable) 
  • Personalisation files and version quantities (where applicable) 

A Professional File Check doesn't include: 
  • Spelling, grammar or proofreading 
  • Design, layout or text sizing advice 
  • Colour accuracy or colour mode checks (RGB/CMYK) 
  • QR code testing 
  • Calendar date checks 
  • Post-print quality inspection beyond our standard production processes 
See a full list of what's included here. 

Adding a Professional File Check won't delay your estimated delivery date, unless we need you to amend and re-upload your artwork after we've reviewed it.

To upgrade to a Professional File Check, simply select the option when you upload your artwork. We'll take care of the rest and let you know if we spot anything that needs your attention before your job goes to print.

What to consider when making branded Boxes?

When designing branded Boxes, concentrate on essential elements that will fulfil business requirements and captivate customers. Ensure your design reflects your brand identity, and select the appropriate size and shape for your products. Opt for durable materials that can withstand the journey like our E-Flute, and consider innovative ways to enhance the unboxing experience for your customers. Why not seal the box with a personalised Sticker for the perfect finishing touch?

What material are your branded Boxes?

Our printed Boxes use White Coated E-Flute, a high-quality, sturdy cardboard known for its durability and strength in packaging. It offers excellent protection for your packaged items, ensuring they reach your customers in perfect condition. The white coating provides a clean, professional look that makes your printed designs and colours vibrant and eye-catching.

Which sizes fit through a letterbox?

If you’re looking to ship your Boxes as a Royal Mail large letter, we’ve got you covered. Here are the sizes that will fit through a standard letterbox:


  • 255mm x 168mm x 22mm (assembled size)
  • 100mm x 100mm x 22mm (assembled size)
And if you're using our Mailer Boxes, you're in luck—all sizes can be shipped as a large letter too! This is perfect for small business owners and e-commerce sellers who want a hassle-free shipping solution.

Need any more help? Just reach out—The Team is here to assist!

How do the Boxes arrive?

Our Boxes are supplied flat-packed for easy storage. This means you can keep a stack of them without taking up much space in your shop or warehouse. Once you're ready to use them, simply fold them into shape - it's a breeze!


Whether you're looking to showcase your brand or elevate the unboxing experience with a custom design, our Boxes come in a variety of sizes to fit your needs. They're also recyclable and fully customisable, with your design on the outside and a sleek white finish on the inside.

What font size should I use for my Box artwork?

For the best results, we recommend using a minimum font size of 12pt for your Box artwork, with 15pt or larger being ideal. Larger font sizes are recommended where possible to ensure your text remains clear and legible when printed on your Box.
