The following table provides a side-by-side comparison of the same tasks in the two software. The left column lists the tasks you would perform in Harmony; the right column lists the equivalent tasks in ColorFlow:

Create a print current curve

  1. In the Print Curves tab, under Calibration Curves, click the Add button .
  2. Add your device in the viewer window.
  3. Click the Properties icon  and define the device condition.
  4. Click the Measurement icon .
  5. You can either measure a chart or import an existing Harmony current curve with real measurement data.

     To measure a chart:
    1. In the Chart tab, click the Add button .
    2. In the Chart Type dropdown list, select Tint Ramp.
    3. Click Save.
    4. Print the tint ramp chart with the device condition that you want to calibrate.
    5. Click Measure.
    6. In the Characterization Print Curve dialog box, choose the print curve used to output the tint ramp chart in Prinergy.
    7. Click OK.
    8. Follow the measurement wizard to measure or enter your measurements.
     To import a Harmony current curve:
    1. Click the Measurements tab.
    2. Click Import.
    3. Locate and select the Harmony file.
    4. Click Open.
    5. Click Close to close the Device Measurements window.
Create print target curve
  1. Click the Conversion icon .
  2. If you want the curve to be visible in Prinergy, select the Show curves in Prinergy check box.
  3. Click the Process Inks tab and select the desired target device condition from the Target dropdown list.
    ColorFlow provides a list of built-in industry CMYK specifications that you can use as your target response. If you can't find the desired target from the list, you can create a custom CMYK Reference device condition as your target.

     To create a custom CMYK reference device condition:
    1. Click the Device Conditions tab and then click the Add icon .
      The Device window appears.
    2.  Drag the CMYK Reference to the viewer window.
    3. In the device condition, click the Properties icon .

    4. In the Name list, type a name.
    5. In the Separate Same As list, select a device type that best represents the black generation strategy of the reference device condition. For the US Web Coated SWOP reference, select Offset  Press - Heatset Web.
    6. Click OK.
    7. Click the Measurement icon .
    8. In the Device Measurement dialog box, click the Add button .
    9. From the Chart Type list, select Tint Ramp.
    10. Click Save.
    11. Click Measure.
    12. Click Enter manually.
    13. Click a color channel (C, M, Y, or K), or in the Channel Binding section, select C, M, Y Same or C, M, Y, K Same.
    14. In the Tonal Response section, double-click the EDA area of a desired tint in, and then enter your EDA value.
    15. Click OK and close the Device Measurement dialog box.
    16. In the Device Conditions list table, find the device condition that you just created and select the Show in Target List check box.
  4. Click the Spot Inks tab and select a spot ink target if applicable.
  5. In the Curves Method list, select Tonal Match.
  6. Click OK.
Create a derived calibration curve based on the print current and target curve

The print calibration curve is generated for you

Edit the print calibration curve:

  1. Edit the print current curve.
  2. Edit the print target curve.
  3. Re-create the print calibration curve based on the modified current and target curves.
  1. Click the Conversion icon 
  2. If you are not satisfied with the color output in one channel only, select and adjust that color channel. For example, you notice that there is an overall magenta cast across all tones, adjust the channel.

    Below the Curve Change graph, there are several sliders that represent different points in the tonal range:   
    Slider

    Tint In Range (non-flexo)

    Tint In Range (flexo)

    Most affectedAffectsMost affectedAffects
    MindotDoes not appearDo not appearMindot Tint InMindot to 25%
    Highlights10%0 to 25%10% to 15%Mindot to 25%
    Quartertones25%0 to 50% 25%Mindot to 50%
    Midtones50%0 to 100%50%Mindot to 100%
    3/4-tones75%50 to 100%75%50 to 100%
    Shadows90%75 to 100%90%75 to 100%

    The value in the box under each slider is a change percentage. The graph appears flat until you make an adjustment.  Move the appropriate slider to adjust the corresponding tonal range or enter the tint out change percentage in the box under the slider.


     
  3. If you want the color output to be lighter or darker in a certain range but you want to maintain the overall color, or if you want to correct a color cast in a certain range of gray, adjust the CMY channels. 

    1. Click CMY.
    2. Select the tonality range (HighlightQuartertoneMidtone, or 3/4-tone) in which you want to adjust the neutral balance.
    3. The displayed color patch demonstrates the effect of your adjustments.

      The color produced before your adjustment is shown on the left. Your adjustment is shown on the right.

      1. To display the color patch in a larger view for easier color comparison, click anywhere in the color patch.
      2. Adjust color cast, lightness, or both by the following:
      • Use the lightness (L*) slider   to make the color darker or lighter. You can also enter the L* value directly in the Color Change columns.
      • Use the cast (a*b*) selector  to adjust the color cast. You can also enter the a*b* values directly in the Color Change columns.
    4. The color patch displays the output color. If the displayed color does not visually align to the color on your proof or press sheet, you can adjust the displayed color in the color patch:
      1. Select the Adjust Displayed Colors check box.
      2. Use the lightness (L*) slider and the cast (a*b*) selector to change the displayed color to align to the color on your proof or press sheet. This color change does not affect any curves or color control elements. You are only adjusting the displayed color of the patches.
      3. To reset the display to the default displayed color, click the Reset icon .
      4. When you achieve the correct color, clear the Adjust Displayed Colors check box.
  4. You can click Calibration Curves to display the curve graph and see the result of you adjustments. 
  5. To preview the effect of your adjustments, click Preview and select an image file.
  6. Click Apply.
