Proofing
Proofing's simple - Jostens will always send you a large package with full size prints of the pages that you recently submitted. Look over them and make any corrections as they instruct you, then give the pages to Ms. More to have her make corrections, sign the pages, rip off the pink sheet, place the pages in the envelope Jostens provided you with, and ship them back off. There are a couple pink sheets in the binder in case you wanted to see what proof checking forms look like.
