How to booklet PDF

  1. Drop the PDF.
  2. Pick the paper.
  3. Press Impose, print double-sided (flip on the short edge), fold.

What happens to your file

The page count is padded to a multiple of four with blank pages at the end, the pages are reordered the way a folded stack needs them — the last and the first on the outside of the first sheet, the second and the second-last inside it, and so on — and each pair is nested two to a landscape sheet by Ghostscript. Print the result double-sided with “flip on the short edge”, fold the stack in half, staple the spine.

The report says how many sheets and how many blanks were added. Up to about forty pages folds well; past that, print in sections.

Questions

My printer asks long edge or short edge?

Short edge, for a landscape sheet — otherwise every other page prints upside down.

Why are there blank pages?

A folded sheet has four faces; a count that is not a multiple of four needs blanks, and they go at the end.
