In the Settings pane of the Fiery Preview window, you can specify imposition settings, and the changes you make are displayed in the Sheet View pane.

Imposition settings are performed with Fiery Impose software. If you have not activated a Fiery Impose license, you can still impose a spooled job in the Fiery Preview window and use Fiery Impose in Demo mode. You will be able to save the job as a .dbp file to the Fiery Server, but not as Adobe PDF. You can print the job with a watermark.
