Color Mode
¾ Select one of the following options:
ˆ
Color: to print the job in color using CMYK.
ˆ
Grayscale: to print the job as black and white using black (K) toner only. 
When a color job is printed using the 
Grayscale option, the cyan (C), 
magenta (M), and yellow (Y) separations are also printed in black (K) toner, 
giving a dense appearance similar to the CMYK grayscale image.
RGB Workflow
1.
In the 
RGB Workflow list, select the required RGB source profile: 
To use the embedded color space array (CSA) or source CSA, select 
Use 
SourceCSA.
To use a Spire or Adobe CSA, select a CSA from the list. The default option 
is 
AdobeRGB1998.
2.
In the 
Rendering intent list, select the required option.
3.
To print RGB gray text and graphics with black toner only, select the 
Print grays 
using black toner check box.
4. Select
 Apply CMYK emulation to convert RGB elements according to the 
CMYK emulation method selected in the 
CMYK Profile list in the CMYK 
Workflow parameter. The RGB elements receive the same look as the CMYK 
elements, creating a consistent appearance.
CMYK Workflow
The 
CMYK workflow option is used to emulate various standards used in 
lithographic printing. These standards represent specific combinations of paper and 
ink, as well as popular proofing systems. The CMYK workflow is also used to 
emulate other digital printers or other printing devices such as offset presses. An 
example of a CMYK workflow job would be printing a test sample for a survey before 
moving to an offset press to print millions of survey forms. In such a case, it is best 
to emulate the offset before the job actually goes to offset printing. The Spire CX260 
supports the device link CMYK emulation methods.
Note:  If the job contains grayscale images that were created in RGB 
applications, such as Microsoft
®
 PowerPoint
®
, specify as monochrome or 
submit to the system with 
Grayscale selected in the PPD file. This 
selection ensures that grayscale images are counted as black and white 
instead of color in both the Spire CX260 and the Xerox DocuColor 242/
252/260 printer/copier billing meters.
Note:  The 
Print grays using black toner check box not only affects 
R=G=B values but might also cause slightly different values 
(R+/-4=G+/-4=B+/-4) to produce gray.
Note:  RGB colors are not affected by the CMYK workflow.
