Imposer for Mac

From ALAP:

Impose pages from a single QuarkXPress document into 2 up or 4 up flats. Unlike other solutions that are currently available to QuarkXPress users, Imposer will not rearrange or shuffle pages in a document - rather reordering is handled in the print stream yielding not only quicker but more reliable results. Imposer will give you full control over creep, bleed, and crossover traps. Whether your production piece is a brochure or a book, Imposer offers a seamless, easy-to-use solution to QuarkXPress. Features Include: Choose 2-Up, or 4-Up - Standard, Work & Turn or Work & Tumble Select Saddle Stitch, Perfect Bound, or Single Sheet binding Flip and move pages within a printer flat Start an imposition at any page in the document Specify the number of pages in a signature Control plate margins, horizontal and vertical gaps, bleeds, crossover trapping, and creep Access registration styles created using the MarkIt 2.x XTension Save frequently used settings as reusable imposition styles Export imposition styles to share them with other users Preview any printer flat; control color depth of previews Display page boundaries, bleeds, and page numbers in previews as necessary Print with standard QuarkXPress controls
