IDImposer is an add-on for Adobe InDesign that enables you to quickly and easily prepare 2-up booklets, N-up business cards, labels, coupons, newsletters, newspapers, magazines, and books, for press, digital printing, or mock-ups – without leaving InDesign, and without buying an expensive plug-in for Adobe Acrobat.
IDImposer works by creating a new "printer spread" InDesign document – representing multiple pages on a sheet of paper – ready for inspection; your original document is unchanged. When it passes inspection, you can then print or export to PDF, after perhaps adding a slug or custom marks to the sheets.
