Bleed
Bleed is the amount of artwork that falls outside of the printing
bounding box, or outside the crop area and trim marks. You can include
bleed in your artwork as a margin of error—to ensure that the
ink is still printed to the edge of the page after the page is trimmed
or that an image can be stripped into a keyline in a document.
A press bleed (that is, an image that bleeds off the edge of the printed
sheet) should be at least 18 points. If the bleed is to ensure that
an image fits a keyline, it needs to be no more than 2 or 3 points.
Your print shop can advise you on the size of the bleed necessary
for your particular job.
Color Management System (CMS)
Software that allows applications and printer drivers to access
information about the color characteristics of monitors, printers,
and scanners. The Color Management System uses the color information
to provide accurate and consistent color to the output device.
Direct Digital Printing
Commercial-quality printing in which electronic source files are
processed directly on the printing press or printing system, rather
than through analog steps such as film image setting and plate making.
Direct digital printing systems may be based on lithographic offset
technology or laser/toner technology. Front-end RIPs and servers are
integrated components of these printing systems.
Dots Per Inch (DPI)
A measure of the resolution of a device. The higher the number,
the sharper the type and images.
International Color Consortium (ICC)
A group of companies chartered to develop, use, and promote cross-platform
standards so that applications and devices can exchange color data
without ambiguity. Founding members include Adobe, Agfa, Apple, FOGRA,
Kodak, Microsoft, Silicon Graphics, Sun, and Taligent.
On-Demand Printing
Commercial-quality printing produced as needed with turnarounds
of a few hours or less. Often associated with very short runs of a
hundred or fewer pieces. A newer class of device - the direct digital
printing system - is usually associated with on-demand printing.
Resolution
The sharpness of text and graphics provided by any printer or output
device, measured in dots per inch.
Trapping
The process of creating an overlap between abutting colors to
compensate for imprecisions in the printing press.
