CMYK Pure Black Process

[On], [Off]*

This setting enables you to specify how monochrome data (C=M=Y=0) should be printed when the device dependent CMYK data is processed using the 'CMYK Simulation Profile' of the machine.
[On]
Monochrome data (C=M=Y=0) is printed using the black (K) toner only, regardless of the selected 'Output Profile' setting.
[Off]
Monochrome data (C=M=Y=0) is printed using CMYK toners based on the selected 'Output Profile' setting.

NOTE
In combination with certain settings, monochrome data (C=M=Y=0) may be printed using the black (K) toner only, even if [Off] is selected. The following are examples:
When [On] is selected for "Pure Black Text"
When [None] is selected for "CMYK Simulation Profile"
When [TR Normal] or [TR Photo] is selected for "Output Profile"
When "Use 100% GCR Profile" in the printer driver is selected
If [None] is selected for "CMYK Simulation Profile", the CMYK Pure Black Process setting is not applied.
