G-104 Glossary
Color Reference Guide for C9800 - 104
SWOP
The abbreviation for Specifications for
Web Offset Publications. A standard of
specifications for separations, proofs,
and color printing on a web offset press
(not a sheet fed press).
TIFF (Tag Image File Format)
A common format for exchanging raster
graphics (bitmap) images between
application programs.
undercolor removal (UCR)
A method for improving wet ink
trapping and reducing ink costs in
process color printing. In shadow areas
where all three process colors (C, M, Y)
overprint, the amounts of those colors
are reduced and replaced by black.
vector graphic
Graphic illustration created on
computers where picture objects are
defined mathematically as lines or curves
between points. These mathematical
definitions are interpreted by an image
language such as PostScript. Vector
images include artwork created with
illustration applications (such as
Illustrator or FreeHand) and page layout
applications (such as PageMaker).
white point
The color temperature of any white light
source, typically expressed in degrees
Kelvin (for example, 6500 K, typical for
the white of a monitor).
workflow
The path a print job follows from
creation to destination. A workflow may
originate with an RGB scan imported to
the client workstation and opened on the
desktop in an image processing
application, such as Photoshop. After
adjustments are made to the scanned
image, it is evaluated on a color proofing
device for eventual color printing on the
same device or on press.
