In the Press Runs view, edit or check both sides of a sheet or web that uses a two-sided work style:

• To preview a specific surface in the workspace, expand the press run in the Press Runs List, and select the front or back of a sheet, or the top or bottom of a web.
• To view the next web in the current press run, select it in the drop list at the top-right corner of the workspace.
• To access the other side of the currently displayed layout for editing, click the Flip tool.
• To check back-to-front layout alignment as if using a light table, use the Transparency slider tool.
• To auto-number the pages on the back of a press sheet or bottom of a web, number the front pages.
