What a free box mockup shows that a flat dieline can’t
A flat print file shows every panel side by side. On the folded box the front meets the sides at a fold, the top tuck closes over the front edge and the glue flap disappears inside, so a band of color can break at a corner or a logo can land on a flap.
A 3D box mockup answers what the flat file leaves open: whether each panel carries the right part of the design, whether the colors run cleanly round the corners, and how the box reads from the three quarter view a shopper sees first.
