Single-page PDFs only • Page count must be a multiple of 4 (4, 8, 12, 16, 20, 24…)

Check this if your PDF was exported as spreads (e.g. from InDesign). The Zine Machine will automatically detect and split 2-up spreads into single pages before imposing.

Scales pages to 95% to fit within standard desktop printer margins while keeping the center spine fold seamless.

How to Print & Assemble Your Saddle-Stitched Booklet

1

Duplex Printer Setting

When printing your downloaded imposed PDF, set your printer to Double-Sided (Duplex) and choose "Flip on Short Edge" (Short-Edge Binding).

2

Stack the Sheets

Collect the printed sheets in the exact order they emerge from your printer. Do not reorder or flip individual sheets.

3

Fold & Nest Individually

For the cleanest, sharpest finish, carefully fold each printed sheet in half individually along the center line, then nest and assemble them together in their correct order.

4

Staple the Spine

Staple along the folded center spine. Ideally, use a 'long arm' stapler (readily available online or in office supply shops for under £10 / $10 / €10) to easily reach across the page to the fold.

Why Multiples of 4?

Each physical sheet of paper folded in half creates 2 leaves (4 printable pages). For example, in an 8-page booklet, Sheet 1 contains Page 8 and Page 1 on the front outside spread, backed by Page 2 and Page 7 on the inside spread. This mathematical arrangement ensures all pages appear in consecutive reading sequence once folded.
