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.
