If you create tailor-made graphics for the box editor and you want them to occupy the entire surface of a wall, add at least a 10 mm margin (the so-called bleed) on each side. This will help you avoid potential shifts of the box during the production processes which might make the edges of your graphics visible on the wall.
In some cases, you might need to include bleeds in the internal side of the diecut template. It might be required in the space where the wings are placed (although they are not visible after the box is assembled). In this situation, we include a bleed in the graphic design of the visible walls.
