If you select an RGB 

 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. When you select PostScript Color Management, a CRD is 
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 
takes effect if the ColorWise RGB Source Profile option is set to None.

For fastest print times, choose JPEG encoding, but inspect printed output carefully 
for unwanted artifacts that may appear as a result of JPEG compression. If you see unexpected 
results in the printed output, reprint the job using Binary or ASCII encoding.

If you select the Photoshop PostScript Color Management option when you save a CMYK 
EPS image, Photoshop embeds PostScript color information that defines the CMYK source 
color space of the image. When you print a CMYK EPS file that contains PostScript color 
information to the Color Server, CRDs are used instead of ColorWise CMYK Simulation 
and Simulation Method settings. Choose the appropriate setting for the Rendering Style 
option.
