Use the Layout Orientation menu in the Settings pane to specify the orientation of a sheet.

1. Click Portrait or Landscape in the Layout Orientation menu.
2. If the booklet style is Nested Saddle, specify the subset size, which is the number of sheets within each subset.

   The number of sheets for the last subset is not a fixed number, and Fiery Impose Plus adjusts the sheets needed according to the actual page count of the job. The default setting for Subset size (sheet/subset) is 2 and the maximum setting possible is 15.
