What is a proof and why is it important that I look at it?

In printing terms, a proof is a one-off copy of your document after all modifications and printing setup processes have been completed. It is your last and best opportunity to make sure that the print job comes out the way you want. By carefully inspecting the proof, you can help us assure an accurate, flawless delivery of your print job on the first run. Proofs can be emailed in PDF format and are useful to check for typos and confirming the overall layout. Because of the potential differences in colors viewed on screen, versus what can be printed, PDF proofs should not be relied upon for color matching. If color matching is critical, viewing an actual "Press Proof" is recommended.
