The imposition dialog allows you to adjust a few essential parameters:
You adjust the sheet size onto which the source pages will be imposed. You can either select one of the default sizes provided in the popup menu, or enter custom values into the Width and Height fields.
If you want to create a magazine to be folded and stapled, select the Magazine option. If you want to create a perfect bound book, that consists of multiple signatures, select the size of the signature (up to 16 sheets per signature).
Enter the thickness of a sheet of paper. PDF Nomad 2 will automatically calculate creep for signatures and offset page content to compensate for it.
The source pages can be scaled up or down to fit the target sheet size, or can remain unscaled, as needed.
The gutter value controls the amount of space added between the left and right halves of the imposed sheet. (See below.)
Use the margin value to ensure no part of the document's contents is clipped when printed. (See below.)
Click [Done] to exit the imposition dialog.
