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.

Note: RGB colors are not affected by the CMYK workflow.

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: The system emulates the selected option during the RIP process. GCR (Gray Component Replacement) and CMYK Emulation do not affect the processed job.
