HOW TO MAKE BLEEDS FOR AN IMAGE OR A BACKGROUND GRAPHIC ITEM
When you place images to the page boundaries is necessary to make the “bleed” (ie an overlap, beyond the page size, of the element positioned at the cut) of at least 4 mm for each side. This precaution serves to avoid that an inaccurate page cut is not detectable by the human eye. In fact, if the image were positioned flush with the format, without a minimum of abundance, and the cut (obviously inaccurate to the tenth of a millimeter) was slightly moved outside the format, you would notice the unsightly white threads to indicate the distance from the end of the image to the cut of the page made in typography.
