P URE BLACK TEXT / GRAPHICS
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:
RGBRed = 0, Green = 0, Blue = 0
CMYKCyan = 0%, Yellow = 0%, Magenta = 0%,
Black = 100%
C OLOR MATCH PRECISION
When the MFP 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.
