The Batch Compare Documents feature compares groups of documents to each other and highlights the differences between them, which are indicated with markups that can be reviewed easily using the Markups list. It provides several auto-matching options to make pairing up pages to be compared simpler. By default, only the content layers of the PDFs are compared; to include markups in a comparison, turn on that option in Advanced Comparison Options.
The batch version of Compare Documents is discussed here. There is also a non-batch version of Compare Documents.
PDFs do not need to be open in Revu when the batch process is run. If a document is open in Revu, any changes resulting from the batch process will be made to the document, but the document will not be saved or checked in (if relevant); the user will need to save and check in the document manually. If a document is not open in Revu, and it is not checked out/locked by another user, changes will be applied and saved to the document automatically (without opening the document in Revu).
In most cases, Revu's auto-matching function will successfully match current sheets with their revisions, but in the event that a consistent naming convention is in place and the auto-matching function doesn't deliver satisfactory results, users can add their own syntax to the matching algorithm. If that doesn't work, or is not an option, manual correlation is always available.
Go to File > Batch > Compare Documents. The Batch: Compare Documents dialog box appears.
Page Region: Uses the text found within user-defined regions of the first PDF listed in the Current Pages list to automatically match documents. To define the page region:
Click and drag to define a region on the PDF. Generally speaking, the data in this region should be located in the same place on each PDF. When the region has been defined, the AutoMark dialog box appears.
Note: AutoMark is most suitable for documents that are vector-based, are the same size and have the same registration. AutoMark might not work as expected if the pages are different sizes, if some of the pages are not searchable or if the scans are not properly registered.
Manual Correlation: Skips the auto-matching process. Select this option to match documents manually on the next screen.
Note: Pages must be matched to be included in the next part of the process. If one of the auto-matching options is selected and matches cannot be found for one or more pages, they will not be included. This does not apply to Manual Correlation, which carries all pages forward.
For each of the Match Pages By options except Manual Correlation, you can define an advanced filter for more control over the auto-matching process. To do so, click Advanced and enter the desired Match Filter. See Advanced Match Options for more information.
Click Match. The appropriate matching process is run (as determined by the Match Pages By selection above) and the next screen of the Batch: Compare Documents wizard appears.
If Manual Correlation was selected as the Match Pages By option on the previous screen and one or more pages are not paired, they are automatically discarded.
Click Options to set additional reporting options. The options available vary depending on what kind of report is being generated:
Create Hyperlinks: When enabled, the report will include hyperlinks to the current, revised, and unmatched pages
Advanced Match Options lets you define a custom Match Filter that is used to precisely match pages during the auto-match process.
* Represents zero or more characters that are not a number # Represents a series of characters that form a number ; Separator for specifying multiple filters ? Represents a series of alphabetic letters \ Escape character to treat above characters as literal
All other characters are literal.
Note: An assumed * wildcard always precedes the string. For instance, A#;C# is implied as *A#;*C#.
Note: A space is considered a literal character. Do not include a space after the semicolon or else the filter will take that space into account as well.
Use the Advanced Comparison Options to fine-tune the document comparison process. It is recommended that you use the default Comparison and Rendering settings provided and change these settings only if the document comparison process does not appear to detect differences.
Three default comparison Types are provided: Printed Documents (same printer), Printed Documents (different printer) and Scanned Documents. Each Type has pre-configured Comparison settings. You can change the settings of any of the default Types or create a custom Type by selecting <New Custom>. The Advanced Comparison Options are:
If you change a value in a default comparison Type, its name is marked with an asterisk (*).
To change the settings of the current type permanently, click Save. The Save Document Comparison Settings dialog box will open. Enter a name for this configuration. If you are changing the settings of a default Type, its name will be auto-populated; you can save it under the default name or change it, creating a new type.
To restore the included types to their default settings, click Restore Defaults.
