So let’s produce an 8-page folded (‘saddle’) booklet.
First, download and install IDImposer. See the instructions on the download page.
Next we’ll make a simple test document.
In InDesign’s Document Setup, make a blank Document with 8 pages. If you are in the U.S., set the Document size to ‘half letter’ (5.5” by 8.5”). If you’re anywhere else, you might want to choose something like A5.
In the Scripts panel (Window / Utilities / Scripts), open the User / IDImposer11.0Folder / RESOURCES / HelperScripts folder, and run the MakeTestDoc.jsx script. This will add Page numbers and Page outlines to our new Document.
Now that we have a suitable test document, Save it somewhere, then run IDImposer, by double-clicking IDImposer11-Pro.jsxbin.
This will bring up the IDImposer main dialog:
The dialog tells us that our Page size is 5.5 by 8.5 inches [or, A5] and that 2 pages would fit side-by-side on a Letter-sized [A4-sized] sheet of paper.
The default Imposition Type for a folded and stapled arrangement, with the folded sheets inserted together, is ‘Saddle’ (Booklet)’.
So all we need to do is to click the ‘Impose’ button.
When we click the Impose button, IDImposer first creates a new 11 by 8.5 inch [A4] output Document. Then it places 2 of the original Pages on each side of the resulting 2 ‘sheets.’
The new Document looks like this:
In the new Document (Fig. 6), original Page 8 and original Page 1 form the ‘front’ side of the first sheet, and Page 2 and Page 7 form the back side of the first sheet. Similarly, the 2nd sheet contains original Pages 6, 3, 4, and 5.
That’s it; you have done your first IDImposer booklet imposition. Congratulations!
You can now print from InDesign, using InDesign’s default/normal print settings. Just print, fold, insert, and staple.
