Where the inner pages extend beyond the outer pages when folded in saddle-stitched booklets?

• A. Creep
• B. Bleed
• C. Margin
• D. Gutter

Answer: (A)

Creep is the slight shifting that happens when folded sheets are stacked into a booklet. In saddle-stitched booklets, the inner pages have to move a bit more toward the spine during folding, so after trimming the stack, those inner pages end up extending beyond the outer pages. Designers account for this by adding creep allowances in the layout, adjusting outer margins so that, once bound and trimmed, the outside edges of all pages align evenly. Bleed refers to printing beyond the edge, margin is the safe space around content, and gutter is the space between facing pages near the spine—none of these describe the edge shift caused by folding like creep does.
