Profile
CMS (Color Management System)
CMS optimizes the color print quality using a color profile that is based on the
characteristics of the printer. With RPCS, the color profile is applied by the driver.
With PS3 and PCL5c, the color profile is applied in the matching/CRD module on
the controller except when using CMM/ICC/ICM profiles.
CMS is not used when the color profile setting in the printer driver is set to "Off."
Gray Correction
Gray correction processes gray with K or CMYK toner depending on the driver
settings.
BG/UCR (Black Generation/Under Color Removal)
The RGB data is converted to CMYK data with BG/UCR. During CMYK conversion,
some CMY data is replaced with K data by the BG/UCR algorithm.
Gamma Correction
The printer gamma can be adjusted with controller SP mode (Gamma Adj.). For
CMYK, there are15 points between 0 and 100%. The corrected gamma data is
stored in NVRAM.
