Pure Black Text / Graphics; Color Match Precision - Oki C9600hdn Printing Manual

P
URE BLACK TEXT
When your document is printed, often the pure black colors will not
be printed using 100% black toner. Instead, these pure black colors
are sometimes converted and printed using a mixture of CMYK
toner.
Using the Pure Black Text / Graphics feature ensures that 100%
black text or graphics in your document is printed using pure black
toner.
This means that the following colors in your documents will be
printed using only 100% black toner:
RGB Red = 0, Green = 0, Blue = 0
CMYK Cyan = 0%, Yellow = 0%, Magenta = 0%,
Black = 100%

COLOR MATCH PRECISION

When the printer performs color matching, it must do many
calculations to convert between different color formats (RGB, CMYK,
etc). These calculations can take time to process.
The [color Match Precision] option allows you to choose between
higher quality color matching (more time consuming) or faster but
less accurate color matching.
