Working with Color
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 using
other color management systems. For example, if you specified a
ColorSync System Profile on the Macintosh computer, the RGB Source
setting specified in the Print dialog box overrides it. In cases where you
don’t want this setting to override another specified source color space,
select Off.
PostScript RGB data is converted to CMYK data using the CRD specified
by the CRD option (see
page 66
). This type of 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.

The source color space defined by this setting is
optimal for color conversions that will be sent to a
KX-P8420 print device. It also allows for consistent
output across different operating systems.
sRGB (PC)
The sRGB (PC) setting specifies the source space
of a generic Windows computer monitor.
Apple Standard
