Book errors .
Hi. I'm pretty new to publishing. I have wrote several books, and submitted my files for publication. after receving my approval copies back from the printers, the books are full of errors, ie. Text and pictures all over the place and not where I placed them, text pictures slipping to next page, unwanted spaces. what am I doing wrong. I checked a few times before sending PDF,everything was ok. but the same problems occur after printing,but are not n my manuscripts. Please help. Thank you.
