  1. In the Print Curves tab, find and click the print calibration curve that you want to edit.
  2. Click the Calibration icon .

  3. 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 M channel.

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

    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.



    You can also view or adjust the shape of the curve directly for each color by clicking Calibration Curves and then make your adjustments.

    1. Click the desired color channel.
    2. Do the following:
      • To view tint out values in the graph and table, click the Tint Out icon  .
      • To view tint change values (Tint Out minus Tint In) in the graph and table, click the Tint Change icon .
    3. Click the point on the curve that you want to adjust, or type the value in the Tint In box.
    4. You can also click a point that you want to adjust and then click two anchor points on either side of the point to constrain a range of your adjustment. The curve will not be affected at tint values outside of these anchor points. 

       

    5. Drag the adjustment point up to darken the output or drag it down to lighten the output, or type a value in the Tint Out/Tint Change box.
      Your adjustment may be restricted in order to keep the curves monotonically increasing.

  4. 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 (Highlight, Quartertone, Midtone, 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.

      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.
