What is Bleed & how do I apply it?
What is Bleed?
Ink that prints beyond the trim edge of the page to ensure it extends to the edge of the page after trimming. As there is a degree of movement when printing on any press, you should always create 3mm bleed on all edges where bleed is needed. Supplying your job without bleed may result in white lines when we trim it.
How to apply Bleed
The concept of applying bleed is the same for all desktop publishing programmes. You need to extend the object box, whether picture or colour, out past the edge of your page. Then, when creating the PDF, you need to set your bleed margins to 3mm.
With Microsoft Word, PowerPoint or Adobe Photoshop you do not have the ability to add bleed when creating a PDF. You need to make your page/image size 6mm bigger at the start. You will then treat the extra 6mm (3mm all round) as bleed, which will be removed when we trim your job. For example, A4 is 210mm x 297mm. Your page with bleed will be 216mm x 303mm.
