■ RGB Pure Black Process
On * , Off
This setting enables you to specify how black and gray data with the equivalent
ratio of R to G to B should be processed when device-dependent RGB data is
converted into device-dependent CMYK data using the RGB Source Profile of the
machine.
If [On] is selected, black and gray data with the equivalent ratio of R to G to B is
printed using the black (K) toner only, regardless of the selected Output Profile
setting.
If [Off] is selected, black and gray data with the equivalent ratio of R to G to B is
printed using CMYK toners appropriate for the selected Output Profile setting.
NOTE
• In combination with certain settings, black and gray data with the equivalent ratio of
R to G to B 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 RGB Source Profile
- When [PS TR Normal] or [PS TR Photo] is selected for Output Profile
- When 'Prioritize Printing of Lines and Text' in the printer driver is selected
• If [None] is selected for RGB Source Profile, this setting is not applied.
■ 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.
If [On] is selected, monochrome data (C=M=Y=0) is printed using the black (K)
toner only, regardless of the selected Output Profile setting.
If [Off] is selected, monochrome data (C=M=Y=0) is printed using CMYK toners
appropriate for 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 [PS TR Normal] or [PS TR Photo] is selected for Output Profile
- When 'Prioritize Printing of Lines and Text' in the printer driver is selected
• If [None] is selected for CMYK Simulation Profile, this setting is not applied.
