Glossary
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).
undercolor removal (UCR)
In shadow areas where all three process
colors (C, M, Y) overprint, the amounts
of those colors are reduced and replaced
by black. This improves wet ink trapping
and reduces ink costs in process color
printing.
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
graphics 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.
