RELATIVE COLORIMETRIC
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.
ABSOLUTE COLORIMETRIC
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.
PURE BLACK TEXT / GRAPHICS
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%
COLOUR MATCH PRECISION
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.
