Press checks for printer errors or anomalies.

Editor who is experienced with pre-press checks scrutinizes the page proofs or bluelines for printer errors or anomalies that may have been missed in earlier production steps. Tasks include extensive cross-checking for layout and consistency and may include making sure the final pages match specs or coding. Tasks occasionally include a light copyedit of typeset text that skipped a copyedit. (Note: It is expensive to edit at this stage.)
