Unfortunately, there is no way to adjust the margins in acrobat.
@straightlife – oh well. There is. But it might be not so straightforward.
I don't know how familiar you are with the Print Production tools in Acrobat Pro.
The easiest way would be to restrict the view of both sides of pages, the even and the odd ones to a new width, that is smaller than the original one (if the layout allows that). Or that is wider than the original plus defining a shift of the contents inside the new page size.
The feature is "Crop Page". And you could apply values to even pages only and odd pages only.
(Or "Even and Odd Pages", but that's not the one we need here)
Just to show you the controls in the "Crop Pages Panel" of Acrobat Pro.
Fact is: you could even expand your page size.
Or set a new Center of the page when using Custom for setting Width and Height.
If the layout does not allow that, that means, only parts of the pages contents should shift, then, I think, it's best to write a script that is moving the main text thread to the middle of the page.
That script would do the following:
1. Set the coordinate system to individual pages.
2. Set the ruler units for x/y to Points
3. When some text is selected inside one of the text frames of your main text thread, the main story, would move all text containers of that story to the middle of the page the frame resides.
4. Resets all values to the original ones set in #1 and #2
It would leave text frames untouched, if they reside on the pasteboard.
I cannot advice further right now, because I do not know how your layout is built.
I could try using the Page Crop Panel in Acrobat Pro with a dummy layout, if you give the page size of your document. The margins are clear. What I need is the exact page size.
I can't figure out why since the space allotted to the frames is still exactly the same. Isn't it?
Try to add inside and outside margins numbers then divide on 2 (1.125+0.625/2= 0.825)
Select master pages then Insert 0.825 for both inside and outside margins and make sure to turn on enable layout adjustment.
1. You always have great advice, but
2. It's WAY too advanced for me. I simply can't understand it.
But thanks for trying and sorry my head is made of wood.
The result is: 0.875
Oh, thanks! I couldn't have figured that out EVER! IT WORKS!!!
