You create bump and tone reproduction curves in Harmony tonal calibration software and then apply them in Prinergy and Prinergy Evo. Harmony software is a separate application that runs on the Prinergy Connect primary server or on the Prinergy Evo server. Harmony software creates a database of curves that must be named CalCurve.hmy in order to be seen and recognized by Prinergy. You can archive and hide curves from Prinergy by changing the name to CalCurve.hmy.TestCurves, for example. Archiving the curves that you don't need will reduce the number of curves that appear in the Calibration menu in Prinergy.
Harmony software uses a number of different types of curves internally (Current, Target, and Calibration curves), but Prinergy and Prinergy Evo only see Harmony Calibration curves.

You can create calibration curves in two ways:

  • Create a curve directly—this is called a transfer curve
  • Derive a curve from a current curve (generally measured press performance) and a target curve (desired press performance)

When using derived curves, for each final calibration curve there must be a corresponding current and target curve; for a total of three curves. Different CMYK color curves can be contained in one curve, but there must be a separate Harmony curve for each spot color. This means that for a press run of CMYK and two spot colors, you must specify three current curves and three target curves, in order to derive three calibration curves (nine curves in total).

Working with Harmony remotely

The Harmony software resides on the Prinergy primary or Prinergy Evo server. It may not be convenient to actually move to the server to create the curves if the server is in another location. In this case, you can download and install the Microsoft Remote Desktop Connection software and log into the server to create Harmony curves remotely.
