of survey forms. In such a case, it is best to emulate the offset before the job
actually goes to offset printing. The Spire CX250 color server supports the
device link CMYK emulation methods.
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 .
To select CMYK workflow options:
1. In the Original list, select one of the following options:
• Direct: to print the CMYK elements without any color
transformation.
• Use Source CSA: to use the embedded CSA from the PostScript
file.
2. In the Emulation list, select the required emulation.
Note: RGB colors are not affected by the CMYK workflow.
Note: The system emulates the selected option during the RIP process. GCR
(Gray Component Replacement) and CMYK Emulation do not affect the
processed job.
