I have a client wanting the complete back catalogue of his journal's hi-res PDFs supplied but without the trim marks, printer's info and bleed. This ought to be easy enough - Acrobat will trim a PDF for me and I can automate the process. Except that it won't. I go Documents > Crop Pages... and set all the options for cropping to the Trim Box, but nothing happens. If I try putting in the page size measurements manually, I get the error message 'Page size cannot be reduced'. Seeing as I've arrived via the Crop Pages option on the document menu I can't think I'm in the wrong place. Why won't Acrobat crop my pages?
I'm on Acrobat Pro 9 fully up to date on OS X 10.6.7
I have this exact same question. It simply won't crop.
Why is this bug not being fixed?
