SignaPrint: PDF Imposition

Turn any PDF into print-ready signatures you can fold and bind by hand.

Features

Real imposition, done for you

SignaPrint reorders your pages so the book reads correctly once every sheet is printed, folded, gathered, and sewn. No spreadsheets, no counting backwards.

8, 16, or 32-page signatures

Pick the signature size that suits your paper weight and your needle. Long documents are split into balanced, numbered sections automatically.

Left and right-edge binding

Build Western codices that open to the left, or Japanese-style and Hebrew or Arabic books that open to the right. The imposition adjusts accordingly.

A5, A4, B5, and US Letter, with crop marks

Print on A5, A4, B5 (JIS), or US Letter. Add optional crop marks and a center-fold line so trimming and folding land exactly where they should.

Single-sided printer mode

Duplex printing not available? SignaPrint can split the output into two separate PDFs—one for all front sides, one for all reverse sides—so you can print both passes manually.

Booklet saddle-stitch mode

For zines and pamphlets, select booklet mode to impose all pages as a single folded section, perfect for hand-stitching with a single row of staples down the center fold.

Preview every sheet first

Step through the front and back of each sheet and review the full signature map before you commit a single page to paper.

Your PDF never leaves the device

Everything is processed locally on your iPhone or iPad. Original page quality is preserved, and nothing is uploaded anywhere.

FAQ

How should I set up my printer for double-sided printing?

Choose two-sided printing with short-edge (short side) flipping, landscape orientation, and 100% or Actual Size scaling. Turn off any fit-to-page or auto-rotate option. Print the first two sheets as a test before running the whole book.

Which signature size should I choose?

16 pages is the usual starting point: four sheets folded together, easy to pierce and sew. Drop to 8 pages for thick or textured paper that resists folding, and go to 32 pages only with very thin stock, since a fat signature makes the inner pages creep outward.

How do I make a book that opens on the right?

Switch binding direction to right-to-left. SignaPrint reverses the page order and the fold logic, which is what you want for Japanese stab binding, or for books set in Arabic or Hebrew.

What happens if my page count doesn't divide evenly?

SignaPrint adds the blank pages needed to complete the last signature and shows you exactly where they land, so you can plan endpapers or a colophon around them.

Does imposing degrade the quality of my PDF?

No. Pages are placed on the new sheets at their original resolution with their aspect ratio preserved, so text stays vector-sharp and images are not resampled.
