RGB source, CMYK source, and Grayscale source
The
RGB source
,
CMYK source
, and
Grayscale source
print options allow you to define the color spaces of the RGB,
CMYK, and grayscale data, respectively, in your document so that the appropriate color conversion occurs on the
Fiery ES.
Commonly used color spaces are available on the Fiery ES. For others, you can import CMYK and RGB custom
profiles to the Fiery ES. Custom grayscale profiles cannot be imported.
RGB/Lab source
When you specify a profile for
RGB source
, the Fiery ES 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 ES 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 RGB
embedded profile
option.
If the
Use RGB embedded profile
option is enabled, the Fiery ES honors objects in the document with RGB profiles,
and objects without profiles are color managed with the RGB source profile from Job Properties.
CMYK source
The
CMYK source
option can be set to any CMYK source profile that is present on the Fiery ES.
To properly manage color in a printed image that was separated using an ICC profile, the same profile must be
specified for printing the image.
The
CMYK 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 Fiery ES with the
CMYK
source
setting.
•
For images that were separated for a press standard, select the press standard as the
CMYK source
setting.
If the job contains an embedded CMYK profile, select the
Use CMYK embedded profile
option. The embedded
profile is applied to CMYK data.
