System information
Separate RGB/Lab to CMYK Source
The Separate RGB/Lab to CMYK Source option determines how RGB colors (as well as Lab and XYZ colors) are
converted to CMYK. This option defines the color spaces that are used by the Fiery Server to separate the RGB data
into CMYK values.
•
When Separate RGB/Lab to CMYK Source is turned on, all RGB colors are first converted to the CMYK
color space defined by the CMYK/Grayscale Source print option before being converted to the CMYK color
space of the printer (as defined by the Output Profile print option). The result is a simulation of the RGB colors
that would be output from a printer with the characteristics defined by the CMYK/Grayscale Source profile.
With Separate RGB/Lab to CMYK Source, for example, if a high-quality ICC profile is available for another
printer, your printer can simulate the behavior of that other printer.
•
When Separate RGB/Lab to CMYK Source is turned off, all RGB colors are converted directly to the CMYK
color space of the printer (as defined by the Output Profile print option).
Spot Color Matching
The Spot Color Matching option provides automatic matching of spot colors in a job with their best CMYK
equivalents.
•
When Spot Color Matching is turned on, the Fiery Server uses a built-in table to generate the closest CMYK
matches of spot colors that the copier/printer can produce. (New tables are generated automatically for each
output profile that you add to the Fiery Server.)
With Fiery Spot-On, the Fiery Server uses the CMYK matches determined through Command WorkStation Spot
Colors.
•
When Spot Color Matching is turned off, the Fiery Server processes the spot color as CMYK data and uses
CMYK equivalents defined by the spot color manufacturer, such as PANTONE. These are the same CMYK
equivalents used by applications that include spot color libraries.
Note: A spot color that is not included in the built-in table is simulated using the alternate color that is provided in
the document.
For jobs that include spot colors, turn Spot Color Matching on unless you are printing proofs of process color
press simulations. In that case, turn Spot Color Matching off and select the appropriate CMYK/Grayscale
Source setting.
Gray and Black (CMYK and RGB)
When the Gray (RGB) option is turned on, any RGB color that has equal R, G, and B values is printed as K-only
black instead of CMYK black. Similarly, when Gray (CMYK) is turned on, any CMYK color where C, M, and Y are 0
(zero), and K is any value is printed as K-only black instead of CMYK black.
You can turn on Gray (RGB) or Gray (CMYK) for either Text and Graphics or Text, Graphics, and Images.
"Graphics" refers to vector graphics. "Images" refers to bitmap images.
The following limitations apply:
•
The Gray (RGB) and Gray (CMYK) options have no effect on a job that is sent as separations.
•
If CMYK Processing Method is set to Pure Primaries, Gray (CMYK) does not affect the output.
•
If CMYK Processing Method is set to Quick, Gray (CMYK) does not affect the output.
