Background

You can import a Harmony transfer curve into ColorFlow and use it as a ColorFlow Source transfer curve to achieve the same tonal correction as the original Harmony curve.

Tasks

Goal
Import a Harmony transfer curve and use as a ColorFlow source curve to output a page in Prinergy. 

Task 1: Import a Harmony print curve

1. In ColorFlow, click the Print Curves tab.
2. In the Harmony Curves section, click Import.
3. Check Show Paper and Film Calibration Curves to make the target curves visible.
4. Select file CF-AG04_Harmony_Print_Curves.hmy.

   • Double-click the PRINT Press A CS1 SWOP 175L curve
   • Click the PRINT Press A CS1 SWOP 175L curve, and then click the Curve icon  in the curve object on the right window
8. Remember the 50% black ink value (52.6%)

Task 2: View the print curves in Prinergy

1. In Prinergy, click Tools > Process Template Editor > Loose Page Output > Virtual Proof
2. Click Virtual Proof.LoosePage.
3. In the Loose Page Output dialog box, expand Calibration & Screening.
4. Select the ColorFlow Current State radio button.
