Hi all,

while testing a possible bug with "SHIFTING" MSO contents (no problems in CS5.5 so far I can tell), I ran into another bug, I think wellknown, in building 2048 x 1536px InDesign CS5.5 files with a folio size of 1024 x 768 px output for iPad 2 and 3.




InDesign CS5.5 v7.5.3 Build 333

OSX 10.6.8


Tested in Adobe Content Viewer on the iPad3

(via USB cable attached)


The ACV on the iPad is the one that came along with DPS v20.


Adobe DPS version:

plug-in version


folio format version



plist version






Folio size: 1024 x 768 px

Orientation: horizontal & vertical




Problem: only the vertical orientation is showing correctly.
When switching the iPad3 from vertical to horizontal orientation a scrollable view of the vertical contents is showing up.


Change the page size of the horizontal oriented InDesign file to 2047.9 px x 1536 px, remove the old folio, build a new one.


Since InDesign CS5.5 does not have a fixed standard preset for 2048 x 1536 px size for files, you are well advised to prepair a  custom document preset for 2047.9 x 1536 px files. Just tested, if 2047.9 px are also good for vertical orientated files and all went well… Otherwise you  need two individual presets…


This rounding error should not occur in InDesign CS6 since a fixed standard preset for 2048 x 1536 px is available there…


I did not change the pages individually from 1024x768px to 2048 x 1536px, but changed the document setup…

    Does your document settings have the units set to points/picas or pixels? Make sure the document settings are pixels, there are definitely rounding errors if you use points/picas. Our recommendation is to always use pixels.

    Ah, I just realized your source InDesign document is 2048x1536. Don't do that Our recommendation is to build your InDesign documents at 1024x768. There's no benefit to designing at the larger size in InDesign, and as you've discovered, some downsides.
