Why does my design need bleed?
Bleed: we print on a larger sheet and trim stacks of them at once. Every sheet can shift a hair under the blade, so background colors and photos need to run 1/8" past the edge. Then the cut always lands in color, never on a white sliver.
Trim: the pink dashed line is the finished size. Everything outside it is cut away.
Safe zone: that same small shift can nick anything right at the edge or crease. Keeping text and logos inside the green lines keeps them clear of the cut and the folds.
