1. Before the proof leaves
--------------------------

[ ] The filename carries a version number that has never been used before
[ ] The version number is higher than the last one the customer saw
[ ] Anything critical sits inside the trim, with bleed where it is needed
[ ] Every page is in the file — including the back, the inside, the reverse
[ ] The customer's own details are the ones they gave you, not the ones
    from the last job
[ ] Finished size is stated on the artwork, not only in the email
[ ] What changed since the last version is written down
[ ] You know who has to approve, and that they can
