I have a 50 page pdf file, A4, RGB. There are no crop marks. I need to add 1/2" to each dimension on each page (centering the image, of course), add crop marks for A4 size, convert to CMYK, to make press ready. I'm having trouble with each aspect of this. When I expand the page size then try to crop to A4, Acrobat tells me that the crop marks may overlap the art and I should consider cropping. I click okay, get the crop window, and that doesn't seem to work either. I'd love to create an action to do this but I can't even perform any of the pieces of it!
I am working on a PC, running Windows 7, Acrobat XI Pro CC.
Thanks,
