shadow around text
Hi, I've just received a first copy of my newest novel and there are about 60 pages where the text looks to have a faint boxed shape shadowing behind it. It's not the text showing through from the other pages either, definitely a square-edged shadowing. I've checked my PDF file that I uploaded to Lulu and that's fine. Never had anything like this with my first two books and wonder if anyone can shed any light on the cause or should I raise it as a ticket issue?
