What I'm trying to achieve
I'm designing a book that will need to be printed and also exported to Interactive PDF for viewing on the web. Ultimately, I want to be able to use the same InDesign file to export to Interactive PDF (for viewing on screen) and bundle to send to a printer (with correct spine margins for binding).
The issue I'm running into
The printer template has built-in margins for the spine of the book (green in the image below) which is causing content to shift from side-to-side when viewing as a PDF.
When I export this document to Interactive PDF and view it in my PDF reader the content is shown one page at a time as usual. Because of the spine margin the content shifts from side-to-side as you scroll. Below is an example of the alternating spine margin when viewing as a PDF. I realize this is necessary for printing, but for viewing on screen it is jarring to see the content shift every single page - ideally it should be centered when viewing on screen.
What I've tried
I've googled a pretty exhaustive list of words to try and come up with a solution for this, but nothing has popped up. It could be that I'm just not using the correct terminology to bring up the results I need. I've also fiddled around with InDesign margin and bleed settings for a good amount of time but haven't been able to solve this one myself yet. Am I missing something simple here?
