Safe margins on gang-run brochures

But seeing ±1.5 mm trim variance on a 16-up gang run (sheetfed), and it’s clipping client art that sits at 2 mm; I’m enforcing 4 mm safety with 3 mm bleed on tri-folds. Does that align with your shop standards, or are you getting reliable results with tighter tolerances?

I’ve stuck with 4 mm on gang runs too, but when I need tighter I ask the shop to add a 2–3 mm gutter and double‑cut the finals; that pulled drift from “±1.5 mm” down to about ±0.7 on a 16‑up. Can your gang vendor accommodate a double‑cut on tri‑folds?
