Frequently Asked Questions
What is a gutter margin in book layout?
The gutter margin is extra margin added to the inside binding edge of facing pages to prevent text and images from being swallowed into the central crease (gutter) when the book is opened.
What is booklet creep (shingling)?
In saddle-stitch booklets, inner folded sheets are pushed outward by the thickness of the preceding sheets. This progressive outward extension is called creep; trimming cuts off more of the outer margin on inside pages unless creep compensation is applied.
