Note: When you import an imposition, you can indicate whether the pages in the
imported imposition should be centered. If you select
Centered
, all pages will be
centered. If you then unassign a page and replace it with another page, the
replacement page will also be centered. You can work with the
Use Page Offsets
,
and
Center Page
menu items to modify their placement as required.
Centering pages
1. In the Imposition Plans pane of the
Signatures
view, select the
pages that you want to center.

3. To see the results of the change, ensure that the
Center Page
,
Offset
, and
Trim Size
columns are visible in the
Imposition Plans
pane of the
Signatures
view.
For pages that were centered:
●
The
Center Page
column now displays
Centered
.
●
The
Offset
column in the Imposition Plans pane of the
Signatures
view now displays the centered offset, which is the difference
between the PDF page's media box and the imposition trim box.
For pages that were not centered:
●
The
Center Page
column now displays
Not Centered
.
●
The
Offset
column in the Imposition Plans pane is the same as the
offset in the
Pages
pane of the
Signatures
view, which is the
difference between the PDF page's media box and the page trim
box.
Returning centered pages to their original offsets
1. In the Imposition Plans pane of the
Signatures
view, select the
pages that you want to return to the original page offsets.
2. From the

The
Offset
column in the Imposition Plans pane displays the original
page offsets and the pages are no longer centered. The values in the
Pages pane do not change.
