Most people will perform imposition onto blank sheets. However, some people will want to use background pages.
Backgrounds allow you to include, perhaps, your company logo or special marks on an imposition automatically. It's almost as easy to work with backgrounds as it is with blank sheets, once you have prepared the background. You should make these pages up to be exactly the correct size.
Note that when you impose on a background you may or may not see the background through the page. This depends on the application creating the pages.
You can use backgrounds for n-Up Pages , Step And Repeat , Manual Imposition , and (not entirely obviously) Insert Blank Pages .
All of these allow you to select from a list of page sizes. If you go to the top or bottom of the list you will see an entry for More Choices . You can select this, then select Define a new custom background . Now you are shown the Define New Background screen. Alternatively, use Imposition Preferences .
You should normally give this background a sensible name. It will then be remembered permanently. If you do not give the background a name, it will be forgotten when Acrobat closes.
After selecting a name, click the Browse button, and choose the PDF file containing the background. In many cases that is all you will need to do. The entire file will be used as backgrounds, though in most cases you will have a background file with only a single page.
The backgrounds feature has a good deal of flexibility.
1. You could define different
backgrounds for even and odd numbered sheets, simply by defining two pages as
the background; the pair will be repeated.
2. You could create a single PDF
file containing many background sheets with different sizes or contents, and set different names for different pages.
3. You could define a front
sheet, then a page to be repeated for subsequent sheets. The sheet to repeat
could be blank.
4. You can define a sequence of
sheets which is only to be used once, if each sheet is numbered in advance.
All of these are easily selected using the options on the Define New Background screen. Options include:
If you choose a range of pages you can also choose whether to repeat all the pages or use them just once. You can also choose to repeat less than the entire sequence.
For instance you could use pages 1 to 2, and then choose Repeat the last 1, this would allow you to work as described in 3, above.
