System information

The CMYK/Grayscale Source profile setting you specify depends on the CMYK profile or press standard for
which the CMYK data was separated. This option affects CMYK data only.
•
For images that were separated using a custom separation (such as a separation produced with an ICC profile),
select the corresponding profile on the Fiery Server with the CMYK/Grayscale Source setting.
•
For images that were separated for a press standard, select the press standard as the CMYK/Grayscale Source
setting.
The CMYK/Grayscale Source option can be set to any CMYK source profile that is present on the Fiery Server.
If you do not want CMYK data in a job to be converted to a CMYK source color space, you can select one of the
following settings:
•
None or Bypass Conversion - These settings send the original CMYK data in the job to the printer without
conversion, but with calibration applied. The None setting or the Bypass Conversion setting is recommended
if you use another color management system instead of ColorWise (for example, ColorSync or Photoshop).
If your document contains an embedded CMYK profile, select None or select the Use Embedded Profile
When Present (CMYK) option. The embedded profile is applied to CMYK data.
Note: For some older models of Fiery Server, the embedded profile is applied to CMYK data regardless of the
CMYK/Grayscale Source setting. For all models of Fiery Server, selecting the None setting or the Use
Embedded Profile When Present (CMYK) option results in using the embedded profile.
•
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 maximum density constraints,
however.
The ColorWise Off setting is available for a specific job but it cannot be the default setting on the Fiery Server.
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.
RGB/Lab Source
When you specify a profile for RGB Source, the Fiery Server overrides source color space definitions or profiles that
other color management systems may have specified. For example, if your document contains an embedded RGB
profile, the RGB Source setting overrides it.
When you specify an RGB source profile, the output from the Fiery Server is consistent across platforms. The RGB
Source options are as follows:
•
EFIRGB - Specifies an EFI-defined color space recommended for users who have no detailed information about
their RGB data.
•
sRGB (PC) - A Microsoft and Hewlett-Packard recommended color space designed for typical home and office
applications.
•
Apple Standard - Specifies the color space of an older Mac OS computer monitor.
•
Adobe RGB (1998) - An Adobe-defined color space, used in some pre-press workflows as the default working
space for Adobe Photoshop.
