Printing CMYK images
Use the following instructions to print CMYK images.
Choose CMYK Color from the Space pop-up menu. Any other setting causes
Photoshop to convert image data to that color space before sending it to the
iR C2100/2100S. (With the AdobePS 8.7 printer driver for Mac OS, these
options appear in the Adobe Photoshop pane of the Print dialog box.)
If you choose JPEG encoding, keep a backup of the original image
N :
OTE
saved with binary encoding until you have seen the printed results of the
JPEG file. Occasionally the compression used for JPEG encoding produces
unwanted artifacts. If you see unexpected results in the printed output of a
JPEG file, use a binary version instead.

Printing tips for advanced users

Use the following information to implement alternate, more complex, color
workflows with Photoshop.
Printing RGB images with Photoshop PostScript color management
If you select an RGB color space and decide to use PostScript Color
Management from the Photoshop pane of the printer driver, Photoshop
sends RGB data to the iR C2100/2100S along with PostScript color
information defining this RGB color space. Remember that when you select
PostScript Color Management, a CRD will be used to perform color
conversions to CMYK.
The included RGB source color space information is overridden by the
N :
OTE
iR C2100/2100S RGB Source option unless it is set to None.
