Bleed is an area added to the edge of your artwork which includes any blocks of colour or background design which reaches the edge of the page.
It is essential to include a 3mm bleed on these edges as we print on larger paper and then trim down to the correct size. Without bleed, the unprinted edge of the paper will be visible, giving your print an unsightly white border.
How to set up bleed in InDesign
When you open a new document, enter your image size, then click “Bleed and Slug”, choose 3mm on all four edges and press create.
How to set up bleed in Photoshop
When you open a new document, enter your image size, and create. Choose canvas size, from the image menu and add 6mm to the width and height of your document, then choose background for canvas extension colour.
Extend any background elements, such as images, colours and text, to 3mm over the edge of the page to reach the bleed border. For example, the artwork size for an A5 flyer is 147.5mm x 210mm, and 153.5mm x 216mm with a 3mm bleed on each side. When converting your design file to a print-ready PDF file, ensure the PDF size is large enough to incorporate this larger page size, for example, an A4 PDF is required to display an A5 flyer with 3mm bleed.
When designing a booklet, odd numbered pages should not include a bleed on the left hand edge, and even numbered pages should not include a bleed on the right hand side, as these pages will sit alongside each other.
Please note, any Just Print jobs supplied without bleed will automatically be enlarged to create a bleed. If the artwork contains text or images close to the edge of the page, this may be fractionally cut off during trimming. If you are not confident in adding a bleed to your artwork, we would encourage you to select our File Check artwork service and a member of our team will ensure your PDF file is perfect before sending to print.
