In order to use Harmony curves in ColorFlow, you must first import your existing Harmony database (Calcurve.hmy) into ColorFlow.
In Prinergy 11 and above, once the Harmony database has been imported into ColorFlow, you can run the Migrate Process Template Curves... utility in Prinergy Administrator to automatically switch all Process Templates from Harmony curves to ColorFlow curves, provided that the Harmony Plate and Print Curves specified in the output process template still exist in the imported Harmony Database.
See Prinergy Workflow Help for full details about the Migrate Process Template Curves... utility.
You can also import individual Harmony curves into ColorFlow and manually enable them in Prinergy Output Process Templates as ColorFlow Curve Source curves.
The following Harmony Migration Training Activities will describe how to manually enable and edit imported Harmony Curves.
