Yes, printer imposition. I have 8 magazines like shown in the first post screenshot. But the printer wants the Cover file to be one spread with Last Cover (C1) and Cover (C2), and the verse spread to be Last Page (7) with page 2 (C3). I've already resolve this by moving the last page (7) paring with page 2 (C3) in all 8 documents. A lot of work.
