Xerox DocuColor 12 Printer with Fiery X12 产品宣传页

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 Fiery. 
(With the AdobePS 8.6 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 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.

Use the following information to implement alternate, more complex, color workflows 
with Photoshop.

If you select an RGB color space and decide to use PostScript Color Management from 
the printer driver, Photoshop sends RGB data to the Fiery along with PostScript color 
information defining the source color space of the image, or the color space of the 
profile chosen in the Space menu. Because this profile is included, a Fiery CRD is used 
to perform color conversions to CMYK.

The included RGB source color space information is overridden by the Fiery 

RGB Source option unless it is set to None.

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.
