Action Lists in Practice
Practical examples of Action Lists
Let’s take a look at a couple of examples of Action
Lists. The purpose of these examples is to give you
an idea of how Action List work in practice.
The examples are the following:
• Compensate for Creep
• Add Printer Marks
Compensate for Creep
Suppose you have PDF documents of booklets that
are almost press-ready. The page 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.
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 integrate an
Action List in your PDF Queue. This Action List can
do the following:
• Shift the printed area of the left-hand
(even-numbered) pages 5 mm to the right
(closer to the binding).
• 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 (e.g. because
this page is not numbered).
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.
