To generate TIF images for one or more documents while in the Review view, simply right-click the document(s) and select Image Document.
This is useful if you need to image something right away so it can be redacted.
This will create a new imaging job and you can track the progress of your print job in the View Jobs interface. (See Viewing Jobs for more information.)
After the imaging job completes, you can check whether or not a document has been imaged by checking the "PREIMAGE" column in the Document List.
A value of "Error" means that there was a problem trying to convert that document to TIF. You will need to add it to a Draft production and attempt to image it again to see what the Error is. (See Draft Productions for details on preparing productions.)
