5-54 Managing Color in Adobe Photoshop
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.
