Identifying the areas of a separation which differ from the original design can be helpful to quantify how good a separation is rather than just comparing it visually. A new layer is created to show you precisely the areas affected and you can use the Pipette Tool to find out the Delta-E differences which are shown in the Info Window.
In this example, we have separated an RGB image into CMYK and we want to identify the areas which differ.
- Make the RGB image visible. Then split the view of the Design Window by pressing the small + in the bottom of the window, as shown below.
- In one view, make only the RGB image visible. In the second view, make only the CMYK image visible.
- Go to Separate Menu > Compare. If you do not have two windows of the same file open, Compare will be greyed out in the Separate Menu and cannot be used.
When the software has completed the process, a message will appear displaying the maximum delta E and the average delta E. A new low resolution layer is automatically added to your file which shows the areas affected. The layer is called Delta-E, followed by a value which is the maximum delta-E between the two separations.
Note: If you have your Notifications set to Mac®OS X® in your General Settings , the message which appears will show in the top right hand corner of your screen as opposed to within the AVA application as shown above.
Note: If your Mac® is on Do Not Disturb, the above message will not appear.
