Typography: are fonts correct; does text break as desired; is justification correct.
Copy: are telephone,fax and cell numbers and email addresses correct;are addresses correct;are people and place names spelled correctly.
Page numbers: is the numbering sequence correct; are page numbers correctly placed.
Prior changes; have all changes to the prior proof been incorporated.
Reader's perspective; from the reader's perspective, is everything clear and comprehensible.
If you notice anything that is not correct, mark it plainly and return the proof to us with instructions. We will correct errors we made for free; we will charge for author's alterations.
