A proof is a one-off copy of your printed document used for visual inspection to ensure that the layout and colors of your document are exactly how they are intended to be. A proof is made prior to sending the document to the press for final printing. Typically, we will produce a proof that will be sent to you online in PDF format or on printed paper, which can be either viewed in our store or delivered to you in person. For multiple-color jobs, we can produce a proof on our output device to show you how the different colors will appear on the final product. Your approval on the final proof is the best assurance you have that every aspect of our work and your own is correct, and that everything reads and appears the way you intended. Mistakes can and sometimes do happen. It benefits everyone if errors are caught in the proofing process rather than after the job is completed and delivered.
