Definition: A press proof is a proof from the printing press, plates, and actual inks specified for the job. A press proof is used to verify images, tone values, colors, and imposition. Because it involves setting up the job and running a proof on the actual paper to be used, it is normally done with the designer on-site (and sometimes your customer as well). It's your last chance to get it right and can add additional cost to the job.
A press proof is generally done in lieu of a prepress contract proof.

Examples:
By the time you get to a press check, typos should be fixed, and layout, font, and image choices finalized. Use the press proof or press check to confirm paper and ink colors and their interaction. Check for registration, page to page color printing/color consistency and the overall appearance of the type and the absence of stray marks or hickeys.
