System information

The example aims to show the PDF documents before and after the Action List has been applied
and the necessary selections and changes to obtain the required result. To be able to create this
sample Action List, you should know how to add the necessary selections, changes and operators.
For a step-by-step description of how to create an Action List, see Creating or editing an Action
List on page 179.
Example: Creating an Action List that changes the page layout
Given: PDF documents of booklets with creep
Suppose you have PDF documents of booklets that are almost press-ready. The pages are to be
printed double-sided, folded and trimmed. You want to make sure that the page numbers, which
are close to the edge of the page, do not get trimmed off. Indeed, when pages are folded for
saddle-stitch binding, the printed area slightly moves outward. This is known as creep in the
publishing world. The more pages in a booklet, the larger the shift of the area of the inner pages
will be.
Figure 79: Creep moves the printed area of the inner pages outwards, which may cause page numbers near
the outer edges of the pages to be trimmed off.
To compensate for this creep, you can create an Action List that does the following:
• Shift the printed area of the left-hand (even-numbered) pages 5 mm to the right.
• Shift the printed area of the right-hand (odd-numbered) pages 5 mm to the left (closer to the
binding).
• Leave the first page unchanged (for example because this page is not numbered).
Figure 80: Changing the page layout: move the printed area of the inner pages (B and C) towards the binding
to compensate for creep, but leave the first page (A) unchanged.
