Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The printing press check is a step in the printing process. It takes place after a printing press is set up but before the print run is underway. While errors should have been corrected during the Color Proofing and proofreading stages, the main purpose of a press check is to make sure that the color on press comes as close as possible to the color proof. Color proofs are valuable guides, but due to the inherent differences between color proofing techniques and printing itself, proofs will match the printed sheet with varying degrees of exactness. While some printing jobs are delivered as printed, most printing is usually not complete until it is converted into a "finished" product. Post press includes various types of finish work such as trimming, embossing, foiling, die-cutting, scoring, folding and bindery.
