www.canva.com is a great website to use to design your documents.
If you choose to use this site for your designing then please ensure you export the file as PDF Print and do not select Crop marks and bleed.
We do not require crop marks on your artwork, however please ensure your artwork is extended to the edge if you need full bleed.
You can add bleed manually by supplying 6mm extra to the dimensions of your file to account for 3mm on each of the four page sides (so that your main document is surrounded by 3mm on every side):
For example, A6 is 148mm (height) X 105mm (width) – So the bleed dimensions will be 154mm (height) X 111mm (width). Flatten your file and save as a high-resolution PDF for best results.
If your artwork looks incorrect on our online previewer, please get in contact via live chat.
