Color Printing 13 Color print options 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 profile used for RGB to CMYK conversions in the prepress workflow on the C9 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. If the job contains an embedded CMYK profile, select the Use Embedded Profile When Present (CMYK) option. The embedded profile is applied to CMYK data. The CMYK/Grayscale Source option can be set to any CMYK source profile that is present on the C9 Server. 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 toner limit, however. The ColorWise Off setting is available for a specific job but it cannot be the default setting on the C9 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 C9 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 C9 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 prepress workflows as the default working space for Adobe Photoshop. • eciRGB v2 - The European Color Initiative (ECI) recommended space for use as an RGB working color space and color data exchange format for ad agencies, publishers, reproduction, and printing houses. • Fiery RGB v5 - An EFI-defined color space recommended for users of office applications. This color space is similar to EFIRGB but is larger and can provide a more desirable blue output. In cases where you do not want RGB Source to override another specified source color space, select the Use Embedded Profile When Present (RGB) option.

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 profile used for RGB to CMYK conversions in the prepress workflow on the C9 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.
If the job contains an embedded CMYK profile, select the
Use Embedded Profile When Present (CMYK)
option. The
embedded profile is applied to CMYK data.
The
CMYK/Grayscale Source
option can be set to any CMYK source profile that is present on the C9 Server.
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 toner limit, however.
The
ColorWise Off
setting is available for a specific job but it cannot be the default setting on the C9 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 C9 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 C9 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 prepress workflows as the default working
space for Adobe Photoshop.
•
eciRGB v2
- The European Color Initiative (ECI) recommended space for use as an RGB working color space and
color data exchange format for ad agencies, publishers, reproduction, and printing houses.
•
Fiery RGB v5
- An EFI-defined color space recommended for users of office applications. This color space is
similar to EFIRGB but is larger and can provide a more desirable blue output.
In cases where you do not want
RGB Source
to override another specified source color space, select the
Use
Embedded Profile When Present (RGB)
option.
