I have a PDF document with one page, containing a large image and some text. I need to add some other PDF documents and duplicate the page with the image 60 times, resulting in a final 70-page document for a professional printer. I've used Preview to do this, but it resulted in a huge file size because the image was always copied. 
Is there any way (app, command line) short of Adobe Acrobat (too pricey) to duplicate a pdf page while just referencing the image?
