2. Signature & Creep Setup
Sheets per signature and paper thickness (gsm or mm) — the center-page shift is computed automatically
How booklet imposition & creep math work
Every folded sheet holds 4 booklet pages (2 on the front, 2 on the back). A document of N pages is first padded with blank pages at the end to N_pad = ceil(N / 4) × 4.
For a signature containing S = sheets_per_sig folded sheets (M = 4S pages), each sheet of caliper thickness t (where t ≈ GSM × 0.00125 mm) folds into 2 paper layers at the spine. Nested inner sheet k (k = 0 .. S − 1) is pushed outward by Δ_k = k × 2t mm, so either the inner pages must be pulled inward by Δ_k or the outer sheets must be shifted outward by (S − 1 − k) × 2t mm to keep fore-edge margins aligned after guillotine trimming.
