Question

Adobe DC is adding extra space around my images, and it's not consistent. How can I make all the pages in my pdf to be the same size?!

I'm guessing your PDF was created from several other PDFs that have various crop, art, trim, media and bleed boxes. One way to confirm this is to go to Acrobat preferences> General> Page Display> Show art, trim & bleed boxes. Assuming all of your pages have the same trim size, this can be fixed by cropping all pages to the trim size,* go to Tools> Print Production> Set page boxes. *If your PDF has bleed, you do not want to crop the pages to the trim size.

If your PDF does have various trim page sizes, the safest way to fix it is to place it into a new document at the desired size, adjusting the size and position of each page as needed, then export to a new PDF.

Note: cropping your PDF does not remove the area beyond the trim, it just hides it for viewing and printing.

    Hi Luke, thank you for responding  

    We are a scanning bureau, one of our feature pieces of equipment is a Planetary Look Down Scanner. This allows us to scan historical bound books, face up, without the need to guillotine the spines.

    Unfortunately, this book must be reprinted, which means we can’t scan it as a spread; all the L & R pages need to be scanned individually, then they’ll be imposed as a book for printing.

    The book size is 150mm x 240mm with an added 3-5mm on the long edge for binding. For some reason, Acrobat Pro assumes the page size is an A4, 210mm x 297mm. Plus it’s not placing the images and text in the centre of the page either.

    It doesn’t matter how we output the images, whether as Tiffs or Jpeg, as soon as the pages are opened as PDF’s, acrobat fills out the page size to that of an A4.

    I’ve followed your instructions and tried resetting the page parameters, but I’m constantly getting an error message saying the page size can not be reduced?

    The other issue is, unless I can find a way to batch process the pages, it will take far too long to crop over 700 individual pages, or manually impose each page into a vector format, like Illustrator or Indesign.

    Kind regards

    Sharon

    So you are using Acrobat to create the PDFs from scanned images and Acrobat is defaulting to the A4 size.

    You could try an Acrobat preflight fix- Tools> Print Production> Preflight> Changes (the blue wrench icon)> Pages> Scale pages to specified size, although this might create unwanted distortion. You could try converting the image to a PDF in either Photoshop or Illustrator, which should retain the actual dimensions of the file. There is an InDesign work-around that would allow you to scan as spread pages and export to single page PDFs, it's a bit off topic but here it is:

    1. Scan as spreads

    2. Create an InDesign file to your single page size, one page, non-facing.

    3. Use the Place Multipage PDF script to generate all pages from your 350 page PDF.

    4. Change the InDesign file to facing pages (spread pages will now span across two pages).

    5. Export to single page PDFs

    I haven't done this in a while, so you might need to tweak these instructions.
