At That's Printing the proofing process is very important to us. One tiny error or omission can ruin an entire project. We go to great lengths to proof every job for accuracy.
What's even more important to us is that our clients have a hand in the proofing process. We feel that the client should be the ultimate judge of their own project.
You might ask why do I need to look at a proof if I've already given you everything I need to complete the job? The answer is we employ human beings to produce your work and, last time we checked, humans are not perfect. Your approval on the final proof is assurance that you have looked over every tiny detail of your work and approve that it is accurate. It helps everyone if errors are caught in the proofing process rather than after the job is completed.
Some clients ask why do I need to approve a proof if I bring my work on a disk? It may seem like a proof wouldn't be needed in this case, however it really is. Output devices process digital information using a variety of processing languages. Your approval of the proof which we will provide assurance that our equipment has correctly interpreted and processed the information that you have provided.
