For fastest print times, 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 from the Photoshop pane of the printer driver, Photoshop
sends CMYK data to the iR C2100/2100S along with PostScript color
information defining this CMYK color space. Remember that when you
select PostScript Color Management, a CRD will be used to perform color
conversions to the CMYK color space of the iR C2100/2100S.
The destination color space for the CRDs is determined by the RGB
Separation print option. By setting RGB Separation to Simulation, CMYK
image is printed according to all specified CMYK Simulation Profile and
CMYK Simulation Method settings. By setting RGB Separation to Output,
CMYK image is converted to the selected Output profile’s CMYK color
space.
Choose other print options (see Chapter 1). The Spot Color Matching
setting has no effect because Photoshop converts PANTONE colors to
CMYK values when you work in CMYK mode.
• If the image was separated for an offset press standard, apply the
corresponding CMYK Simulation setting. For example, if the image is
separated for SWOP, choose SWOP as the CMYK Simulation setting.
• If Photoshop is configured for a custom separation using ICC profiles,
select the corresponding profile from the CMYK Simulation print option
for the iR C2100/2100S.
NOTE: The above custom simulation setting requires that the same profile
used for separation in Photoshop also resides on the iR C2100/2100S. For
more information on downloading CMYK Simulation profiles to the
iR C2100/2100S with ColorWise Pro Tools, see page 4-5.
