Below you'll find helpful tips: 4 rules for designing the perfect fit

1) Make sure you've accounted for the 'bleed' in your design, filling this area with any background colours or images. Ensure all important parts of your design are kept within the safe area.

2) Where possible designs featuring graphics or text should be submitted as vector based PDFs. To keep your text in vector format, we recommend applications like Adobe Illustrator, Adobe InDesign and more recent versions of Adobe Photoshop. Please note, saving text in JPEG format could result in 'fuzzy' edges.

3) When your design features a mix of photography and text, make sure your placed photographs are 300 dpi, and where possible that your final design is saved as a PDF.

4) Make sure you pre-flight your PDFs using the 'Adobe PDF/X-1a:2001' preset. This option can be found in Adobe Illustrator, Adobe InDesign and more recent versions of Adobe Photoshop.
