The Overlay option lets you easily add a company logo or other fixed item to every page of PDF files you create. It also lets you place artwork or other fixed items onto just the first page of your PDF files, together with items that change from file to file.
There are two places in the program where you can define how pages of PDF documents should be overlaid:
Overlay Options panel and
Overlay dialog box.
Overlay Options panel
Select Overlay files as one PDF document from the Assemble selection box in PDF Create Assistant. The Option button becomes available if this item is selected. Click this button to display the Overlay panel where you can define how pages should be overlaid.
Click one of the nine squares. The default position is Page Center.
Overlay dialog box
Select Overlay with existing file in the If File Exists selection box on the PDF Settings panel of the PDF Create! Properties dialog box.
The newly created PDF will be overlaid with the existing file. Click the Overlay button to control how the overlay should be performed. The Overlay dialog box will appear where you can define the merge rules and other options.
