OLOR ISE RINT
• is an Adobe-defined color space, used in pre-press as the default
Adobe RGB (1998)
working space in Photoshop 5.
• is the European Color Initiative (ECI) recommended space for use as an
ECI-RGB
RGB working color space and color data exchange format for ad agencies, publishers,
reproduction and printing houses.
• is an EFI-defined color space recommended for users of office applications.
Fiery RGB
This color space is similar to EFIRGB but is larger and can provide a more desirable
blue output.
• specify the definitions you download as RGB source profiles.
Sources 1-10
If you are printing with the PostScript driver and have enabled Two-Way
Communication, the name of each downloaded profile appears in the RGB Source
Profile setting menu. If Two-Way Communication is not enabled, downloaded profiles
appear as Source-1 through Source-10. For more information about Two-Way
Communication, see Printing from Windows
• instructs the CX3641MFP to allow the RGB sources you defined elsewhere, such
None
as in the application, to be used. When you set RGB Source to None, the appearance of
colors is not independent of the file type. For example, RGB EPS files looks different
from RGB TIFF files.
With RGB Source set to None, PostScript RGB data that contains a source color space
definition is converted using the CRD specified by the Rendering Style option (see
"Rendering Styles" on page 92). Non-PostScript RGB data and PostScript RGB data
that does not contain a source color space definition are converted using a general
undercolor removal (UCR)

Spot Color Matching

The Spot Color Matching option provides automatic matching of spot colors with their
best CMYK equivalents.
• The CX3641MFP uses a built-in table to generate the closest CMYK matches of
On:
spot colors your copier/printer can produce. (New tables are generated when you add
new output profiles.)
With Spot-On, the CX3641MFP uses the CMYK matches determined through Spot-On
(see page 59).
• The CX3641MFP processes the spot color as CMYK data and uses CMYK
Off:
equivalents defined by the spot color manufacturer, such as PANTONE. These are the
same CMYK equivalents used by applications that include spot color libraries.
N : Spot colors that are not included in the built-in table are treated as CMYK.
