Glossary
Prepress proof
A print made from a set of film separations, or from
an electronic file, to simulate the results of printing.
A film proof is the last opportunity to catch
problems before the final printing.
Presentation graphics rendering
A color rendering style that does not try to precisely
match printed colors to displayed colors. It is
appropriate for bright saturated colors used in
illustrations and graphs.
Process colors
The four ink colors used to simulate full-spectrum
color images: process yellow, magenta, cyan, and
black.
QuickDraw
Graphics and display technology built into
Macintosh computers. QuickDraw applications rely
on QuickDraw rather than the PostScript language
to send words and pictures to printers.
Raster image
Electronic representation of a page or image using
a grid of points (called pixels) that are numerically
defined. Raster images can be black and white,
grayscale, indexed color, or photographic quality
color.
Separation
The process of separating a color image into the
primary color components for printing—cyan,
magenta, yellow, and black. Also used to refer to
the four sheets of film that result from the process
of separating a color image.
Source profile
A profile used by KX-P8420 to determine the
context for the color values specified in a digital
image.

Spot color
A color that is printed on its own separation plate
when separations are specified. A spot color is
printed using a special ink for that color, in contrast
to process colors that are printed using
combinations of cyan, magenta, yellow, and black.
Status T
A spectral response for graphic arts reflection
densitometers defined by ANSI (the American
National Standards Institute.)
Subtractive color model
A system in which color is produced by combining
colorants such as paint, inks, or dyes on media
such as paper or transparent film or acetate. The
subtractive primaries are cyan, magenta, and
yellow. All printing devices use the subtractive
color model, as do photographs and transparency
film. Many printers use cyan, magenta, yellow, and
black colorants.
Subtractive primaries
Cyan, magenta, and yellow colorants used in
subtractive color systems. Combining the
subtractive primaries produces darker colors.
SWOP
The abbreviation for Specifications for Web Offset
Publications. A standard of specifications for
separations, proofs, and color printing usually
designed for magazine production.
Vector image
Graphic illustration created on computers where
picture elements are defined mathematically as
lines or curves between points. Includes artwork
created in illustration and page layout applications.
