Color Management
RGB Source
The RGB Source option is used to provide a source color space definition for RGB
data in your document. The setting you specify for this option overrides any source
color space profiles you may have specified with other color management systems. For
example, if you specified a ColorSync System Profile on your Mac OS computer (see
page 2-11), the RGB Source setting overrides it. In cases where you don’t want this
setting to override another specified source color space, choose the Off setting.

EFIRGB
is recommended for printing to the DocuColor 40 CP. The source color
space defined by this setting is optimal for color conversions that will be sent to a
DocuColor 40 CP print device. It also allows for consistent output across different
platforms.
•
sRGB (PC)
specifies the source space of a generic Windows computer monitor.
•
Apple Standard
specifies the source space of all standard Mac OS computer
monitors.
•
Other
allows you to specify custom RGB source settings. If you choose Other as the
RGB Source setting, you can choose settings for the Gamma, Phosphors, and White
Point options.
If you set RGB Source to
Off
, PostScript RGB data (such as RGB EPS images) and
nonPostScript RGB data (such as RGB TIFF images) are converted differently by the
DocuColor 40 CP color management system.
• PostScript RGB data is converted using the CRD specified by the Rendering Style
option (see page 2-9). PostScript RGB data contains its own source color space
information which is used as a reference point for the conversion.
• NonPostScript RGB data is converted using a general under-color-removal
conversion method. NonPostScript RGB data does not contain source color space
information and so cannot be converted using a CRD.
