We require 5mm of background extension past the edge of the piece to make up the bleed. Most design packages will give you the option to add a bleed to any design. Some packages, such as Photoshop, don’t enable you to add a bleed. In this case, you’ll need to manually make your artwork 5mm larger on all sides of your artwork.For example, if your sticker is 100mm x 70mm, add 5mm to each side resulting in the dimensions being 110mm x 80mm.
