Setting Parameters in the Job Parameters Window 191
Use the CMYK workflow parameter to specify the required rendering intent for
CMYK elements. All printers, monitors, and scanners have a range of colors
(gamut) that they can output (or view, in the case of a scanner). If a color needs to
be output and is outside the gamut of the output device, it must be mapped to
another color that exists within the gamut.
Use rendering intent to compress out-of-gamut colors into the color capability of
the press you are using. You can select any rendering intent value for CMYK
elements from the
Rendering intent list. The default value for CMYK is Relative
Colorimetric.
In addition, you can emulate the paper tint and adjust the white point value of the
used paper stock. For example, if you want to simulate pink paper while using white
paper, use the corresponding emulation profile and select
Emulate source paper
tint.
The CMYK workflow parameter is also used to specify the desired rendering intent
for CMYK elements.
To select CMYK workflow options:
1. In the CMYK Profile list, select the desired CMYK profile.
2. In the Rendering intent list, select the desired option.
3. To emulate the original paper tint, select the Emulate paper tint check box.
4. Select the Preserve pure colors check box to preserve pure cyan, magenta,
yellow, and black during transformation.
Spot Workflow
By default, the Spire CX260 searches the spot color dictionary for the correct value
each time there is a spot color with a recognized name.
Note: The system emulates the selected option during the RIP process.
GCR and CMYK emulation do not affect the processed job.
Notes:
• If you selected Device Link as the emulation method, Rendering
intent is unavailable because a rendering intent is already defined for
each device link emulation.
• Custom CMYK Device Link emulations are available only if you have the
Pro Basic or Pro Control Station configuration.
Notes:
• The Emulate paper tint check box is available only if you select Device
Link as the CMYK profile.
• When you select the Emulate paper tint check box, the Spire CX260
applies the absolute colorimetric rendering method.
• When you select the Emulate paper tint check box, the RGB
Workflow > Apply CMYK emulation check box is selected by default.
• If the job is simplex, only the front side is printed using the tint
emulation.
• Paper tint emulations are available only if you have the Pro Basic or Pro
Control Station configuration.
