Printing CMYK EPS files saved with PostScript color management
If you select the Photoshop PostScript Color Management option when you save a CMYK
EPS object, Photoshop embeds PostScript color information that defines the CMYK source
color space of the object. When you print a CMYK EPS file that contains PostScript color
information to the Color Server, RGB print options are used instead of ColorWise CMYK
source profile and processing method options. Choose the appropriate setting for the
Rendering Intent option.
Printing CMYK objects 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 the PostScript color information defining
this CMYK color space. When you select the PostScript Color Management option,
a rendering intent is used to perform color conversions to the CMYK color space of the
Color Server.
The destination color space for the rendering intents is determined by the Separate RGB/Lab
to CMYK Source print option. If the Separate RGB/Lab to CMYK Source option is enabled,
the CMYK object is printed according to all specified CMYK/Grayscale Source and CMYK
Processing Method settings. If the Separate RGB/Lab to CMYK Source option is not enabled,
the CMYK object is converted to the CMYK color space of the selected output profile.
Setting the Color Server print option Spot Color Matching to On has an effect only if you use
the Photoshop Multi-Channel feature to define spot channels, and then save the object in
EPS format and open it in another application. For more information, see the documentation
that accompanies Photoshop.
Photoshop converts spot colors to CMYK values when you work in CMYK mode.
• If the object was separated for an offset press standard, apply the corresponding CMYK/
Grayscale Source setting. For example, if the object is separated for SWOP, choose SWOP
as the CMYK/Grayscale Source setting.
• If Photoshop is configured for a custom separation using an ICC profile, choose the
corresponding profile for the ColorWise CMYK/Grayscale Source option.
The previous custom CMYK setting requires that the same profile used for separation in
Photoshop also reside on the Color Server. For more information about downloading CMYK
Source profiles to the Color Server with Command WorkStation, see Command WorkStation
Help.
