EFI Fiery ES IC-418 - Separate Rgb;Lab to CMYK Source

The CMYK source option can be set to any CMYK source profile that is present on the Fiery ES.
If you do not want CMYK data in a job to be converted to the output color space, you can select one of the following
settings:
•
Bypass conversion - This setting sends the original CMYK data in the job to the printer without conversion, but
with calibration applied.
•
ColorWise OFF - This setting sends the original CMYK data in the job to the printer without calibration applied
and without converting the CMYK data. The CMYK data is still subject to the total ink or toner limit, however.
The ColorWise OFF setting is available for a specific job but it cannot be the default setting on the Fiery ES. You
select this setting for a specific job.
Note: When you print with the ColorWise OFF setting, make sure that the options you choose in your application
do not cause the application to modify CMYK data. You must specify no color management in the application
when you print with the ColorWise OFF setting.
Grayscale source
The Fiery ES supports separate processing of jobs with Device Gray and ICC Based Grayscale through their own
color conversion. For FS200/FS200 Pro and earlier, the grayscale color spaces were processed through the CMYK
color path.
The Grayscale source profile setting provides factory-installed grayscale profiles to use for source-to-output profile
color conversion. Users cannot import their own grayscale ICC profiles.
If the job contains an embedded profile associated to grayscale objects in the document, select the Use Gray
embedded profile option.
The Grayscale source option can be set to any of the factory-installed grayscale source profiles that are present on
the Fiery ES.
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 ES 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 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 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).
