Printing
Imposition layout
Imposition means arranging the pages of a book on the printing sheet so that they are in the correct order after printing, folding and assembly. This tool works through an example to help explain how it works. Print shops calculate using their own machine dimensions and allowances; different figures are normal and not an error.

The top row is upside down. Applies to work-and-turn printing; other turning methods give a different arrangement.
- The results are a guide to understanding how it works, not a binding calculation. Each print shop uses its own machine formats, cutting sizes and allowances, so actual calculations will differ.
- One printing sheet = front and reverse printing. If several folded sections fit on one printing sheet, they are printed as repeated layouts.
- Choose paper with the grain parallel to the spine; otherwise the book will warp.
- Cover, endpapers and headbands are not included.
