Glossary
Additive color model
A system in which color is produced by combining 
primary lights additively. The additive primaries are 
red, green, and blue. When added together in 
proper amounts, these colors produce white. An 
RGB video monitor is based on an additive color 
model. 
Additive primaries
Red, green, and blue light that is used in additive 
color systems. The additive primaries combine to 
produce white.
Banding
Visible steps between shades in a gradient.
Bit depth
Amount of information required for each pixel in a 
raster image. Black and white images require only 
one bit per pixel. Photographic quality color images 
can require 24 or 32 bits per pixel.
Calibrated RGB
An RGB color space used by KX-P8420 color 
management software as an interchange standard. 
The Calibrated RGB color space is defined 
according to the following specifications for a color 
monitor: SMPTE phosphors, a white point D50, 
and gamma of 2.2.
Calibration
The process of ensuring that a device behaves 
consistently with respect to a set of specifications.

Color rendering dictionary (CRD)
A feature found in PostScript Level 3 color printers 
that gives improved matching between the monitor 
and printed output. Color rendering dictionaries are 
used by the printer’s PostScript interpreter when 
converting RGB data sent to the printer to CMYK 
data used by the print engine.
Color rendering style
A feature of KX-P8420 color management software 
that allows you to maintain the best possible 
translation of color from one color device to 
another. The KX-P8420 color rendering styles are: 
photographic transparency and presentation.
Color space
A model for representing color in terms of 
measurable values, such as the amount of red, 
green, and blue in an image. RGB and CMYK color 
spaces are based on color devices—monitors and 
printers respectively. Other color spaces, such as 
CIELAB are based on mathematical models, and 
are device-independent—they are not based on 
the color response of a particular device.
Colorant
An ink, die, toner, paint or other pigment that 
modifies the color of what it is applied to.
Composite printer
Any printer that can print directly in color without 
first creating color separations. A composite is an 
early proof of a printing job.
Continuous tone
An image containing gradient tones. 
Custom color system
A system of named color swatches that can be 
matched on press using process or spot colors. 
PANTONE and TruMatch are examples of custom 
color systems.
