Xerox DocuColor 12 Printer with Fiery EX12 Dépliant

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).

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.

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). 

The color temperature of any white light 
source, typically expressed in degrees 
Kelvin (for example, 6500 K, typical for 
the white of a monitor).

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.
