  • Full Color response: The relationship between input tints and output colors in CIELAB, representing all possible process ink tint values on the device. You can generate Gray Balance curves and ICC profiles, from a Gray Balance response.
  • Gray Balance response: The relationship between input tints and output colors in CIELAB, representing primarily the Black and near-neutral CMY tint values on the device. You can generate Gray Balance curves, but not ICC profiles, from a Gray Balance response.

    : The relationship between input data and:
    • for CMYK inks, the resulting Effective Dot Area (EDA) on the printed press.
    • for extended process inks, the resulting spot color tone value Spot Color Tone Value (SCTV) on the printed press.
    • for spot inks, either or both of the resulting EDA or SCTV on the printed press.

  1. In ColorFlow, add the device and define the device condition.
  2. In the device condition, create choose and export a measurement chart.
  3. Create a custom print transfer curve to control the response of the device. This step is optional. ColorFlow provides several built-in transfer curves for you to use. You can create a custom transfer curve if you don't want to use the built-in transfer curves. For flexographic presses, you should always create a print transfer curve to control the Mindot behavior.
  4. In Prinergy, output and print the chart by selecting a built-in or the custom transfer curve in the Process Template.
  5. In ColorFlow, measure the printed chart.
    Note: At the beginning of the measurement wizard, a dialog box appears asking you to specify the print curve you used to print the chart. In the dialog box, from the Print Curve list, select the print transfer curve you created.
    After the measurement is completed, the color response for the device condition is established and the print transfer curve you created becomes the device curve of the device condition. That device curve will be included in the print calibration curve delivered to Prinergy for output to the device.

  1. In ColorFlow, add the device and define the device condition.
  2. In the device condition, create choose and export a measurement chart.
  3. For a curve-controlled device, define the device curve to control the response of the device.
  4. In Prinergy, output and print the chart by selecting the device and the device condition. For a curve-controlled device, select the Print Characterization mode.
  5. In ColorFlow, measure the printed chart
    Note: For a curve-controlled device, at the beginning of the measurement wizard, a dialog box appears asking you to specify the print curve you used to print the chart. In the dialog box, select the Selected by Prinergy Color Relationship Management: Print Characterization Mode check box.
    After the measurement is completed, the color response for the device condition is established and the device curve you created is associated with the measurement. If you redefine the device curve, you must redo your measurement.

You can also characterize color responses of a device condition by the following:
