Applying Redactions

A redaction is used when confidential information needs to be hidden in a produced document.  Redactions placed using the Concordance Viewer are transparent and can be edited, moved, or deleted similar to other markups.  Once a document is produced, redactions cannot be edited or removed in the produced file and any text or images concealed by a redaction cannot be viewed, copied or searched.

The Redaction tool allows you to place one or more redactions over various areas of sensitive information within a document.  In Concordance Viewer, the redaction appears transparent to allow you to make sure the redaction covers the information you want to conceal.  When a production is executed, the redaction becomes opaque concealing the information underneath.

Since PDF files are not flattened or burned, when producing PDF files the redacted information is removed from the file before the redaction is placed.  The production process physically removes the hidden text from the produced file, the original document is not altered.

Redactions can be applied to specific text, or they can be applied as a box over an area of a document or image.  It is recommended to us a different color for redactions than other markups.  This ensures that the markup type can be easily differentiated when viewing a document or image.


If you need to produce text files, you will need to OCR the produced images after the redactions have been burned into the production output, or you can choose to scrub redacted text when generating a Production.


When redacting a bullet or numbered list, it is recommended that you apply redactions using the Area Redaction tool. This ensures that the list content is completely redacted when the content is produced and/or printed.


All redactions are produced as black when Black & White is selected in Image Settings for the production output.  Color redactions will appear as set by the user when Color is selected for the production output.
