This is your opportunity to check the copy against the original manuscript. You are responsible for changes made to the copy not caused by typesetter error, including errors made because the manuscript was in poor condition. Don't let a pressing deadline intimidate you into inadequate proofing. It takes longer to do a job twice than to do it right the first time. Use standard proofreader's marks so that you and your designer know exactly what changes you want.
Deadlines Be reasonable and honest when asking for a deadline.
Work backwards from the delivery date to come up with the deadline of when your job has to be taken to the printer. If you ask for a prompt deadline, be prompt in proofing and picking up your order. If your rush job is left on the shelf for a week after completion, it may not be as easy to get your next rush job rushed through. If a project is hurried through too quickly, there is more opportunity for costly mistakes to be made. Remember even minor errors that must be corrected once the job reaches the press are expensive.
