For print providers, finished art PDFs supplied as readers spreads can create a nuisance. So that the imposition software can correctly impose the pages in the correct order for press, the pages have to be presented as individual pages as opposed to readers spreads. Rather than inconvenience a customer and ask for the file to be prepared again, it is easier to split the PDF into individual pages, but until recently this procedure was a tedious method of copying and pasting a PDF into an InDesign file set as spreads and then preparing an output PDF as individual pages.
However, this blog has provided two solutions so far to do this:
Now a third method exists. This method uses both Acrobat and an InDesign script.
1) With the “spreads” PDF open in Adobe Acrobat, save the document as single pages. This can be done (in Acrobat X) by using the split document feature and splitting into 1pp documents;
or (in Acrobat 9 or above) by extracting pages as single pages.
Put these PDFs into a folder of their own.
2) Create a new InDesign file the correct finished trim size, as readers spreads, and the same amount of pages as the intended finished artwork.
3) Once the file is created, run this script: A prompt will ask for the folder of PDFs to import – navigate to that folder and click OK.
4) A prompt will warn once the file is finished. All that is then left to do is tidy up the first and last pages that are centered within the spreads, they only need to be centered within their appropriate pages and any unnecessary pages deleted.
I’m not sure who was the original author of the script but can only credit those who contributed to the forum where the script was adapted for this purpose.
