I am not a pre-press person but need an understanding of a frequent problem encountered from every Graphic's person our company hires.
When a clients Ad Agency sends us a PDF file that is lets say 4.5mb that prints fine and then later wants us to make a minor type change. Our new files size increases x10 or more to 55mb and graphics can not seem to explain why. or correct the issue without downgrading the resolution noticably. These are files with no type issues, no outlines. the only variance may be original creation in Indesign vs Illustrator or CS5 vs CS6.
