Inside bleed overlapping other page when exporting as spread

[benjamin.a]

Hi,

I'm having some difficulty exporting a spread without the bleed of one of the pages overlapping the other one.

So I have a background on every page to make the paper look like some sort of old scroll.

Every scroll paper has 3mm bleed on each side since it will be sometimes used on left side and sometimes on the right side.
But for some reason one page is always overlapping another (since InDesign puts spreads in the same layer structure instead of two separate ones). (fig 1)

I want to have a result like fig 2 when exporting as spread but still be able to export them as singles with bleed on each side without needing to manually crop every inside of every page...

I tried making single pages and shuffling them back to a spread with a gap between them to zero-out the bleed (fig 3) but then I just get a spread with a double inside bleed. (fig 4)

So is there a way to to this without the hassle of manually cropping every page? Maybe by merging singles back to spreads in Acrobat Pro?
But I can't find how to crop the inside bleed then...

Thanks!

How is this being bound (saddle stitched, perfect bound etc)? Most binding doesn't require inside bleed.

Hi Danny, I know that the bleed isn't necessary, but if I remove the inside bleed I would have to manually crop every scroll paper on the inside.
Otherwise I get the result as shown below.
As you can see, the right page is overlapping the left page.
What I want is that the inside bleed is cropped in the middle where the crop mark is.

I was wondering why this isn't an option when exporting a pdf since this would be a lot less time consuming.

It looks like you have these pages on the Master Pages? You need to crop them at the spine on the Master pages. if they extend past the edge of the page, they'll overlap each other like you see. make sure that they stop at the spine and that should resolve the issue on the document pages.

The easiest way to handle background art like this is run a single image as a crossover:
