Xerox CX User Manual - page 66
Individual job pages can contain RGB, CMYK, and spot color
elements. A spot color is a specially mixed ink that enables you to
reproduce colors that are difficult to reproduce with CMYK inks.
The CX print server Spot Color Editor enables you to edit the
values of every spot color in the Spot color dictionary. You can edit
these values without affecting the graphics, images, or lineart
page elements.
When a spot color is converted to CMYK for digital printing, the
printout doesn’t always simulate the desired spot color. The spot
color variations feature enables you to easily edit a spot color by
selecting a more appropriate shade. The spot color variations
feature provides 37 variations, with slightly different CMYK values.
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 PANTONE
®
color and HKS
®
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.
