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.
Printing CMYK EPS files saved with PostScript Color Management
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 Fiery, CRDs are used instead of
ColorWise CMYK Simulation and Simulation Method settings. Choose the
appropriate setting for the Rendering Style option.
Printing CMYK graphics 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 Fiery along with PostScript color information
defining this CMYK color space. When you select PostScript Color Management, a
CRD is used to perform color conversions to the CMYK color space of the Fiery.
The destination color space for the CRDs is determined by the RGB Separation print
option. If RGB Separation is set to Simulation, the CMYK graphic is printed
according to all specified CMYK Simulation Profile and CMYK Simulation Method
settings. If RGB Separation is set to Output, the CMYK graphic is converted to the
CMYK color space of the selected output profile.
Setting the Fiery 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 image
in EPS format and open it in another application. For information see your Photoshop
documentation.
