All four printer spreads for a 16-page booklet
This is the print order for one left-to-right saddle-stitched signature, counting the outside cover as pages 1 and 16. Every row is one physical sheet. Read each face left to right as you hold that side upright. The sheet numbers start outside and move toward the center fold. The middle spread in the finished booklet is pages 8 and 9.
| Sheet | Front left | Front right | Back left | Back right |
|---|---|---|---|---|
| 1 · Outer | 16 | 1 | 2 | 15 |
| 2 | 14 | 3 | 4 | 13 |
| 3 | 12 | 5 | 6 | 11 |
| 4 · Inner | 10 | 7 | 8 | 9 |
How to check the sequence by hand
Fold four blank sheets together in half. Hold the booklet closed and write 1 on the front. Turn each leaf and number each visible page in ordinary reading order until you reach 16 on the back. Open up the sheets again and compare both sides against the table. This small proof makes the page relationships visible, especially when deciding how duplex backs are oriented on your feed path.
As an arithmetic check, each printer spread pairs pages that add to 17. The outer front is 16 plus 1, and the inside center is 8 plus 9. The sum rule confirms the pair, while the dummy confirms which page belongs on each side of the fold. Check left and right placements as well as the page numbers.
Worked example for 60 copies
Four sheets per copy times 60 copies requires 240 physical sheets before waste. Each has two printed sides, so the finished run accounts for 480 side impressions. If you allocate eight extra sheets for tests and spoilage, pull 248 sheets from stock. The material allowance is not a guarantee of sellable copies. Check that each finished booklet has one of every sheet, and replace any sheet rejected after printing or folding.
If your cover uses a different stock, split the requirement into 60 cover sheets and 180 inside sheets before any extra material. Plan separate setup allowances if you change trays or run the cover independently. If your designer supplied a separate four-page cover plus 16 interior pages, the booklet has 20 pages total and needs a different sequence.
Print and fold a proof first
If your PDF is in reader order, booklet mode can arrange the spreads for you. Adobe’s Acrobat booklet printing instructions explain the options. With an imposed two-up PDF, use ordinary duplex printing and leave booklet arrangement off. Before printing all copies, fold a proof and check readability, order, upside-down backs, the finished size, and whether inner pages protrude too much at the open edge.
Common imposition mistakes
Check that pages with no printed number still occupy a position. Reorder only once and verify the final PDF page size before choosing a paper tray. A separate cover, right-to-left binding, or multiple signatures changes the production plan. Use this table only for the standard 16-position, left-to-right arrangement described here.
Frequently asked questions
How many sheets does one booklet use?
Four duplex sheets make 16 page positions. Each sheet has two pages on each face.
Which pages are the inside covers?
Page 2 is inside the front cover. Page 15 is inside the back cover.
Which duplex flip setting should I use?
Print the numbered proof and check the backs after folding. The correct option depends on your printer and the orientation reported by its driver.
What if my PDF has only 15 pages?
Add a blank where it belongs in reading order and keep the intended back cover last. The general booklet calculator can show the padding too.
