I'm fairly new to designing for print and I was hoping someone would know how to add bleed to a shape like the one below. The printer is requesting bleed of 3mm to add to the image, I have no idea how to add it to an image that's irregular like the one below. any help would be much appreciated.
A bleed is used to print a slightly larger page, then trim it to size, so that elements that are supposed to continue off the edge of the page (like a background) don't have a gap, even if the cut is slightly off target. If there is supposed to be a white border with nothing printed, you don't need to add anything, but otherwise you probably want to carry on the shape like this:
