Creating solid cutback curves

We strongly encourage all existing Harmony users to switch to ColorFlow for calibration curve creation. There is no current requirement in Prinergy to switch, but because ColorFlow simplifies the creation and application of curves and brings the ability to align print conditions to modern standards like GRACoL or G7, we strongly recommend you start using ColorFlow for all future curve creation. 

There are a couple of current limitations to keep in mind when migrating from Harmony to ColorFlow. 

  1. Although you can import your existing Harmony curves into ColorFlow, you cannot currently edit an imported curve (to be enabled in a future version of ColorFlow). So there is no practical value in importing existing Harmony curves into ColorFlow, as you would have to return to Harmony to make any edits to those curves.  So we recommend that you can just continue to use legacy Harmony curves in existing Process Templates. But create all new curves in ColorFlow and reference those ColorFlow curves in new output Process Templates. 
  2. If you still use copydot files in production and need to calibrate them on output, you will likely need to continue to use Harmony. (This is a Prinergy Process Template limitation, not a ColorFlow limitation.) It is possible to create a copydot calibration curve in ColorFlow and export it as a Harmony Curve (calcurve.hmy), but managing a large number of copydot calibration curves realistically requires using the Harmony application. 

So to recap, our recommendation is to use ColorFlow for all new curves, but just leave legacy Harmony curves as they are in existing Output Process Templates.

ColorFlow 7.5 simplifies curve creation and application. We strongly suggest you create new curves in ColorFlow rather than Harmony, because of ColorFlow's many advantages. However, there is no mandatory requirement to switch from Harmony in Prinergy 7.5.

We recommend you move to ColorFlow in a phased and controlled manner. You can start by creating new ColorFlow curves for new print conditions, but continue to use existing Harmony curves in existing Process Templates for legacy print conditions.

Note that ColorFlow is the only option if you wish to align a print condition to a modern standard like GRACoL or G7.

The new curve creation process in ColorFlow is straightforward if you are printing and measuring charts. For other situations, consider the following:

  • If you are creating curves based on a spreadsheet of values (node-based curve creation), see instructions here.
  • For Copydot calibration, you must still use Harmony curves.

    ColorFlow 7.5 vereinfacht die Erstellung und Anwendung von Kurven. Wir empfehlen Ihnen die Erstellung neuer Kurven in ColorFlow und nicht in Harmony, da ColorFlow viele Vorteile bietet. Dennoch ist es absolut notwendig, von Harmony zu Prinergy 7.5 zu wechseln.

    Wir empfehlen Ihnen, den Wechsel zu ColorFlow allmählich und in gesteuerten Schritten zu vollziehen. Sie können beispielsweise damit beginnen, neue ColorFlow-Kurven für neue Druckzustände zu erstellen, die vorhandenen Harmony-Kurven können Sie jedoch zunächst in den vorhandenen Vorgangsvorlagen für ältere Druckzustände weiterverwenden.

    Beachten Sie, dass ColorFlow die einzige Option darstellt, wenn Sie einen Druckzustand an einen zeitgemäßen Standard wie GRACoL oder G7 anpassen möchten.

    Der neue Kurvenerstellungsprozess in ColorFlow ist einfach und direkt, wenn Sie Tafeln drucken und messen möchten. Für andere Situationen sollten Sie Folgendes beachten:

    • Wenn Sie Kurven basierend auf einer Wertetabelle erstellen (Knoten-basierte Kurvenerstellen) möchten, sehen Sie sich hier die Anweisungen dazu an.
    • Für die Copydot-Kalibrierung müssen Sie weiterhin Harmony-Kurven verwenden.
