Design guidelines
To make artwork setup simple, we recommend downloading the relevant template from the 'Product Templates' section above. Don’t forget to follow the template instructions and delete the 'guide' layer before exporting your design to a PDF.
For best printing results, ensure your artwork and images are CMYK. If you use RGB, Pantone or spot colours in any element of your artwork, we will automatically convert them to CMYK which may change your colour profile.
To eliminate any font issues, make sure all fonts are ‘embedded’ or ‘converted to outlines’ before creating your PDF print file. To ensure legibility, we recommend using a minimum font size of 10pt.
For optimal image print quality, ensure all images are 300dpi to 450dpi. Anything lower than 300dpi will give poor image quality. Images higher than 450dpi will result in high file sizes and may cause longer upload times.
To avoid alignment issues during cutting, be sure to include ‘crop marks’ (offset 10mm) and ‘document bleed’ when exporting your artwork file to PDF. Refer to our product templates for the required bleed specifications.
To meet our print requirements, ensure your file is exported in Adobe PDF (Print) format, ideally as PDF/X-1a: 2001.

How to print with Canva
We provide free Canva templates for many of our products to make artwork setup quick and print-ready. If this product shows a Canva symbol above, click it to open the correct template in Canva. Each template includes the right size, bleed and safe zones. After designing and downloading, return here to order your product.
If you do not see a Canva option here, you can still browse our full collection of Canva-compatible templates to find products that work.
A new tab will open with the template preloaded for you. Be sure to remove the template guides before exporting your final file.
Set your design to CMYK for the most accurate print results. RGB files will be converted to CMYK, and colours may change slightly.
Use fonts available in Canva at 10pt or larger. Keep all text within the safe area to ensure legibility after trimming.
Upload high resolution images (300 DPI or higher). Lower resolution files may look blurry or pixelated when printed.
Extend backgrounds or images into the bleed area to avoid white edges. Keep important text and logos inside the safe zone.
Export from Canva as PDF Print and select 'Crop Marks and Bleed' before downloading. After your artwork is finalised and downloaded, be sure to upload it when placing your order with WTTB.
