You can use the Layout Orientation menu in the Settings pane to specify the orientation of a sheet.

1. In the Layout Orientation menu, select one of the following:
   • Portrait
   • Landscape
2. If the booklet style is Nested Saddle, specify the Subset size option, 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 sheet(s)/subset setting for the Subset size option is 2 and the maximum value is 15.
