FoldProof booklet guide
How to set booklet creep without clipping pages
Nested folded sheets push inner leaves outward. In the common cover-fixed workflow described by Adobe, the cover stays fixed while inner pages move progressively toward the spine. FoldProof keeps this optional and off by default because paper, finishing and printer behavior still require a physical proof.
1. Begin with zero
Print a folded proof without compensation and measure the real displacement. Paper thickness, sheet count and finishing method matter more than a generic preset.
2. Apply a maximum per-page offset
The outer sheet stays at zero while compensation grows toward the inner sheet. Record the maximum per-page value and each sheet's calculated share rather than applying one flat shift everywhere.
3. Push both panels toward the spine
On each inner sheet, the physical left panel moves right with a positive x offset and the physical right panel moves left with a negative x offset. The center fold stays fixed, every page is aspect-fitted to its full panel and each panel is clipped independently.
4. Enforce a hard limit
A utility should cap extreme requested values and show that cap. FoldProof limits the maximum per-page push-in to 18 points so a mistaken entry cannot silently move content far outside the printable panel.
5. Reprint the physical proof
Check margins, folios, center spread and blanks again after changing creep. The recorded setting is evidence of intent, not a replacement for the finished-paper test.
