Imposition Plan

What it does

• Imposition is a decision about which pages share a sheet.
• Grain direction and bleed must survive the layout, not the other way round.
• A plan written once removes the guesswork at the plate setter.

How to use it

1. Leave room for crop marks and a colour bar outside the trim box.
2. A work-and-turn layout halves press passes but doubles the need for precise back-up.
3. Mark the spine side of every page on the plan, not just on the first form.
4. If the sheet is short by one page, add a blank rather than shrink the margin.

Safety notes

• Do not rotate text stock to fit more pages; the fold will crack and the page will curl.
• Check that the bleed on the outer edges is not trimmed away by the press sheet edge.
