I currently have a print ready version of a brochure in a PDF format, I need it to be adjusted. I no longer have the original AI. file. It currently shows print marks and I need the print marks to be removed and the pages to be split to 1 page (they are currently 2 to a page as the print is to be folded in the centre). The purpose of the adjustment is to have the brochure in a format that can be easily sent via email.
