Glossary
Creep In a saddle stitched booklet the
bulk of the paper causes the inner pages to extend further out
than the outer pages when folded. When trimmed the inner pages
are narrower than the outer pages.
The illustration above shows an exaggerated
view of how the inner pages of a saddle stitched booklet "creep"
out and extend beyond the edge of the outer pages when folded.
Creep Allowance
Adjusting the page layout of inner spreads to maintain a constant
outer margin when the saddle stitched booklet is trimmed.
Problem Creep varies
depending on the thickness of the paper and the number of pages.
If there is no creep allowance, when pages are trimmed the outer
margins become narrower toward the center of the booklet and
there is the possibility that text or images may be cut off.
Solution If creep
is noticeable, copy can be repositioned toward the center of
the spread for those pages in the center of the booklet. When
trimmed, all pages will have the same outer margins and no text
or images are lost. Some page layout software can automatically
calculate and adjust layouts for creep -- moving the page elements
of affected spreads in small increments.
The illustration below
shows how page elements are adjusted in small increments over
a series of spreads.
