Do I need a special file setup for staggered cut orders?

Yes. Because every panel has its own trim size, the artwork has to account for where each cut falls.

• Map your content to each panel's unique depth so nothing important sits on a cut line.
• Add bleed on all sides and keep key text inside each panel's safe zone.
• Use the product template, which shows bleed, safe zones, and trim lines for every panel.
• Design the stepped edge on purpose, since the exposed panel strips are prime space for headings or tabs.
