Page Creep

Suppose you are producing a 24-page Saddle Stitch Booklet, in 6 Sheets. (Each Sheet contains 4 Pages — 2 on the front side, and 2 on the back side.)

  1. Stack 6 blank sheets of the paper stock that you will be using.
  2. Measure the thickness of the stack.
  3. In IDImposer, typically you will want to specify the Outer Creep as the stack thickness, with an Inner Creep of 0.
    (Alternatively, you can have the Outer Creep be half of the stack thickness, and the Inner Creep also be half of the thickness, but negative.)
  4. Click the ‘Impose’ button.
  5. Now look at the output doc. Note that the text and other contents of the ‘outer’ sheet (Page 24 / Page 1) have been shifted away from the fold, by approximately the amount of the specified Outer Creep. But the contents of the ‘inner’ sheet (Page 14 / Page 11) will not be shifted at all.
  6. Print, fold, staple.

Note that, with thick saddle stitched booklets, you must take care not to have contents very close to the outer edges of the outer sheets, or some of the contents may be clipped or nearly-clipped.

If you like formulas:

shiftAmountForThisSheet = outerCreep – (sheetIndex * (outerCreep – innerCreep) / (numberOfSheets – 1))

where sheetIndex is zero-based.

IDImposer-ing a PDF file

InDesign 2017.1 Crash

Summary:

Please download the current release of IDImposer – 2017.05.28, at this writing. Otherwise, if you update to InDesign CC 2017.1, InDesign will crash after running IDImposer. Even if you just show the IDImposer dialog and immediately hit Cancel.

That is, to avoid the bug, either use IDImposer11 2017.05.28 (or newer), or don’t install the InDesign CC 2017.1 Update.

Discussion:

The dot release of InDesign, CC 2017.1 (a.k.a. 12.1.0.56), has a UI bug that affects IDImposer and many other scripts.  (InDesign CC 2017.0 and prior releases are fine). The behavior of the bug is that IDImposer runs to completion, but then InDesign 2017.1 crashes, and you have to restart InDesign in order to view the IDImposer output doc.

For a more detailed description of the problem, see: https://forums.adobe.com/thread/2308052. A bug report has been submitted to Adobe.

Please download the latest version of IDImposer, dated 2017.05.28 (or later), which works around this issue.
