Chapter 8 – Setting Parameters

Color Mode

Select one of the following options:

Color: to print the job in color using CMYK.

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

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.

In the

Rendering intent list, select the required option.

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.
