Printing RGB images with Photoshop PostScript Color Management 
If you select an RGB color space and decide to use PostScript Color Management, 
Photoshop sends RGB data to the Color Server along with PostScript color 
information defining this RGB color space. Note that when you select PostScript 
Color Management, a CRD will be used to perform color conversions to CMYK.

The included RGB source color space information is overridden by the 
ColorWise RGB Source option unless it is set to None. The ColorWise Rendering 
Style option specified will take effect if the ColorWise RGB Source Profile option is set 
to None.
For fastest print times, you can choose JPEG encoding, but check printed output 
carefully for unwanted artifacts that can appear as a result of JPEG compression. If you 
see unexpected results in the printed output, print the job again using Binary or 
ASCII encoding.
Printing CMYK images with Photoshop PostScript Color Management
If you select a CMYK color space and decide to use PostScript Color Management, 
Photoshop sends CMYK data to the Color Server along with PostScript color 
information defining this CMYK color space. Note that when you select PostScript 
Color Management, a CRD will be used to perform color conversions to the CMYK 
color space of the Color Server.
