A proof of the job from the printing press.

A proof used to check the result of the entire printing process. It is the most complex control tool in the printing process; its greatest advantage is that it provides a realistic impression of the final product, independent of the preprint process. Machine proofs come closest to the printed result when produced on the paper to be used for the print run.

Proof made by printing from plates, as opposed to using plastic proofing techniques. Also known as wet proof.
