Reply To: simple format automation needed.

It depends on which program originally made the PDF. You could also open the PDF in Acrobat and set page bounding boxes there, but you’d still need to place all the pages into your InDesign document. Ideally, it would be best to get the native files and fix the problem there.

But of you’re placing each page into InDesign and correcting the trip and crop, you could set up the graphic frame with an Object Style that sets the graphic with a particular fitting and placement. That way, you could set up the graphic frames (on your master pages) for each of your facing pages, and then load all the PDF pages into your place gun and place the pages all at once.
