Colour matching (advanced) > 73

This option is best for printing solid colours and tints. Use Relative 
Colorimetric when printing from a drawing program such as 
Adobe Illustrator, or Macromedia Freehand.

This option is recommended if you are proofing images on your 
printer that are intended for final output on a printing press. This 
may result in a visible colour cast on your print as it will also try 
to simulate the paper white of the target device.

When your document is printed, often the pure black colours will 
not be printed using 100% black toner. Instead, these pure black 
colours 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 colours 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%

When the printer performs colour matching, it must do many 
calculations to convert between different colour formats (RGB, 
CMYK, etc.). These calculations can take time to process.

The [Colour Match Precision] option allows you to choose 
between higher quality colour matching (more time consuming) 
or faster but less accurate colour matching.
