It is often useful to be able to manage even and odd pages separately. For instance, to do double sided printing on a printer which can only do one side at a time, or to make a systematic change to the fronts and backs separately.

Shuffle Even/Odd Pages offers four choices.

• Do not re-order pages does nothing by itself. But you can optionally choose to reverse the order of the even pages, or turn the even pages upside-down. This can modify an existing document, or create a new copy.
• Rearrange so all the odds are first, followed by all of the evens . This can be combined with reversing the order of the evens, or turning all evens upside down. This too can modify an existing document, or create a modified copy. There is no direct way to undo this rearrangement.
• Split into two new documents , one from odd pages, the other from even pages. The documents can be separately processed, and joined again if required. This is not available in automation sequences.
• Join two documents together , assumed to contain even and odd pages from the previous function (though they can come from other sources). You select two open documents from a list. This is also not available in automation sequences.

As with most imposition functions, shuffling pages can damage links and bookmarks.
