The spot color variations feature enables you to set:
The variation of cyan, magenta, and yellow dot percent, by
selecting variations of 1-7%. The default selection is 2%.
The change in the hue, by selecting variations in the cyan,
magenta, yellow, red, green, and blue axis
The brightness, by increasing or reducing the K value by up to
20%.
You can assess your changes immediately in the Before and After
boxes, or you can print the entire set of variations, and decide
which best fits your requirements by examining the printout.
The edited spot color is saved in a custom dictionary. When the
CX print server identifies a spot color in a job, it first looks for the
name of the spot color in the custom dictionary and uses the
associated CMYK values. If the spot color is not found, it looks in
the spot color dictionaries. If the spot color is not found in either
dictionary, the CX print server uses the CMYK values embedded
in the original file.
Selecting a spot color variation
1. From the Tools menu, select Spot Color Editor.
2. In the Color list, type the name of the spot color.
The spot color is automatically selected from the spot Color list.
3. Click the Variations button.
The Variations dialog box appears. The spot color is in the
center of the color patches and is designated as "0".
4. Click and slide the Variation steps slider to see the different
variation steps between 1 to 7 color units of the original value.
Each unit refers to a dot percentage of the original value.
5. To see the CMYK values of a color patch, roll your mouse over
the color patch.
The CMYK values appear in the bottom left corner of the
dialog box.
6. To select a variation of the spot color, click on the desired color
patch.
You can see the difference between the selected color patch
and the original spot color in the Before and After box.
