Edit a spot color

You can define the CMYK values of a spot color by typing the numerical values, by selecting a visual match from a pattern of color swatches, or by measuring the color of a physical object using a measurement device.

The Spot color matching print option automatically matches spot colors with their best CMYK equivalents so that spot colors can be simulated using the CMYK colorants. However, you may want to adjust the default CMYK equivalents to achieve a better match for your specific printing conditions. You can modify spot color definitions using Spot Colors.

Open Device Center in one of the following ways:
- Click the More icon (three vertical dots) next to the server name in the Servers pane.
- Double-click the server name in the Servers pane.
- Click Server > Device Center.
- Right-click the server name and select Device Center.
Click Spot Colors under Resources.
Find and double-click the spot color.
Do one (or a combination) of the following:
- To edit the CMYK percentage values directly, click in the C, M, Y, or K field and type a new value. Use the Tab key to move from one field to the next. The new color is displayed next to Current Pick.
- To select a new color visually, click a color patch in the lower area of the dialog box.
  
  The selected color becomes the new Current Pick and is displayed in the center patch of the center cluster. Neighboring patches show updated hue variations from the center patch, in the hue directions indicated by the colored arrows. The left and right clusters show variations of saturation or brightness (whichever is selected for Tuning mode) from the center cluster. To control the degree of variation in the neighboring patches, move the slider closer to Fine (for smaller variation) or Coarse (for larger variation).
  
  Note: When you select certain colors, an exclamation point icon may appear in the upper-right corner of the dialog box. This icon indicates that one or more colorants have reached their maximum values.
- To select a new color using a measurement instrument, see Measure and import spot color values.
To print a test page, click Print. Matching spot colors accurately on a monitor is very difficult. Always print a test page to get the proper color match.
