IDImposer Change History

For more recent changes, see IDImposer_Release_Notes.txt.

27 August 2020

  • Added a Proxy button, for quickly creating page-numbered test Documents.
  • Switched to Marc Autret’s elegant ProgressBar.

15 July 2020

  • removed some redundant PageSequence files and added a few new ones. two of
    the new ones were requested by customers. the others filled in a few gaps.

30 May 2020

  • removed AddPageNumbers.jsx, and improved MakeTestDoc.jsx a bit

11 May 2020

  • removed the #target directive from HelperScripts. the wrong version of InDesign
    was being started up.

4 May 2020

  • fixed a couple of bugs relating to the interaction between the Layout Units
    setting and the Suggested Sheet Size setting.

1 May 2020

  • cloned AddPageNumbers.jsx into MakeTestDoc.jsx (more descriptive), and
    worked around a File.openDialog problem that was hanging InDesign CS6 on the Mac.
  • renamed MultiPlace.jsx to PDFMultiPlace.jsx (more descriptive).

18 Mar 2020

  • Fixed the ability to turn off foldmarks/centermarks/tweenmarks.
    I already had the UI; but unchecking it just hid the ‘inner’ foldmarks,
    not the foldmarks on the edges of the overall trimbox.
    (Gotta set spaceBetween to > 0 for this to be obvious.)
    See the ‘DePicture’ email for the bug report.

22 Nov 2019

  • fixed my enableContentAwareFit fix, for older InDesign CC versions.

18 Nov 2019

  • added CrossFold 8-page, 16-page, and 24-page PageSequences.
  • minor changes on Windows.
  • wrote a new installer script for Windows.

6 Nov 2019

  • ensure that enableContentAwareFit is turned off during an IDImposer run,
    otherwise placed frozen pages can get slightly scaled up, causing overlaps, etc.
  • added the CrossFold32.xml PageSequence template.

1 July 2019

  • updated warning alert messages to reflect the fact that there is a patch now for the
    Mac 14.0.2 InDesign “nested” dialog bug.


  • Added warning about the dialog bug in Mac ID 14.0.2.


  • Added some newer, simpler 2×2 PageSequences, and removed the rather archaic ‘Work-And-Turn (WT)’ PageSequences. (If you are actively using some of the WT layouts, please let me know.)


  • Fixed a few edge cases in the Imposition Engine


Problems fixed:

  • Sheets Per Signature > 1 were not being handled correctly.
  • Restricting to first 1 or 2 or 3 Output Sheets was broken.
  • Sheets Per Signature (in Options panel) setting wasn’t ‘sticky’.
  • Right-Hand-Side Binding (in Options panel) was partly broken.


  • Strengthened support for multi-signature PageSequence files.
  • ImpositionTypeManager and PageSequence and IDImposer Engine architectural enhancements.


  • Fixed a problem with hidden resource fork files that begin with dot-underscore (‘._’). This mainly affected people trying to use PageSequence files on Windows.


  • Fixed the “Missing JSON” build problem.


  • Added an option to output just the first few sheets of an imposition.


  • The UI is now more responsive.
  • You can now turn Marks on or off from the Layout panel as well as the Marks panel.
  • Fixed a problem with the display of the current Acrobat PDF ‘Freeze’ settings.
  • Fixed a problem with the display of current Registration settings.


  • Simplified the UI for specifying sheet dimensions. Let me know what you think.


For this release, we have an important bug fix, related to the new release of InDesign CC (2019), and some new PageSequence files.

  • The bug causes IDImposer to crash or silently quit when a user upgrades to InDesign CC 2019.
  • The new ‘PerfectPlus’ PageSequence files are targeted mainly toward those customers who produce 1 copy of a custom book.  It’s like the “Perfect Bound” Imposition Type, except that you can fit more pages per sheet, if you use larger sheets of paper. In fact, “Perfect Bound” is a special case of ‘PerfectPlus’, where the layout is “2×1” pages per surface.


I went “back to school” for this latest release of IDImposer, and made some much needed enhancements to especially two areas:

  • Installation of customizable presets for standard press metric and north american paper sizes, and
  • A much stronger collection of ‘work-and-turn’ imposition patterns, for people who want to
    • produce your own books, including the folding / trimming / binding phases; or
    • produce folding signature dummies to help you communicate clearly with your print services supplier, and better understand the interactions between the design and the manufacturing of books; or
    • produce booklets more efficiently and inexpensively, through cost savings in time and materials (paper).

Please give them a try, and let me know what you think!

The Download page.


  • IDImposer now supports Japanese book order imposition! Just choose RHS Binding in the Options panel.   (My apologies that the UI for IDImposer is still in English only!)


  • Decided to phase out Booklet Edition.
  • Now there is just IDImposer Pro, which is FREE, for producing small to medium sized jobs. Larger jobs still require purchasing a license.
  • No more ‘Free Trial Period’.  There is no need, now that IDImposer Pro is free for small to medium sized jobs.
  • Made numerous smaller changes and bug fixes.
  • See also the notes on the download page.


  • Work on streamlining the UI; and making the UI hopefully a bit prettier and less intimidating.
  • Performance improvements.

Reorganized and regenerated the SupportFiles file, _SC_II_A_SupportFiles.jsx.

12 August 2015

Am now enforcing the requirement that the source doc must be saved and not modified since the last save, to prevent someone from imposing an older version of the document and being confused.

The dialog values weren’t getting updated properly by Apply Geo Layout.

Fixed some File.openDialog filter issues.

Improved error handling for Preset page dimensions not exactly the same as the source document’s page dimensions. Makes Avery presets and others much easier to use.

14 July 2015

Improved the consistency of the printer marks default settings with those of the InDesign print system.

10.0.0 – March 2015

Total rewrite and redesign (again) to avoid using Flex, since Adobe is now backing away from Flex as the way to do Extensions to Adobe products.  IDImposer 10 (10.0.0) released in March of 2015.

9.0.0 – 2012

Total rewrite and redesign to create IDImposer 9, a Flex app, the Latest and Greatest thing for Adobe developers to build with, according to Adobe.


Earlier, quite primitive, mostly free versions. The first publicly available version dates back to about 2005, I believe.
