ECHNOLOGY
The magicolor 2210 printer’s entire color system is built
around a technology called Q
COLOR
. One of its most
dynamic features is the ability to automatically optimize
color output, allowing even a novice to produce profes-
sional quality, color documents without the use of sophis-
ticated manual optimization techniques. Q
COLOR
encom-
passes much more, however, including these built-in and
software-supported color control features:
•ColorDepth
™
screening
•Color matching (PostScript and/or ICC-based)

CREENING
Line screening and halftones are factors that highly
influence color image rendering. In conventional printing,
color images are composed of tightly arranged dots (or
halftones) that are spaced in a regular pattern and appear
solid to the eye. Tonal changes are made by changing the
size, or amplitude, of each dot. This technique is known as
amplitude modulation, or AM screening.
Q
COLOR
provides a pre-set AM halftone setting, referred to
as ColorDepth. ColorDepth is designed to eliminate moiré
patterns, and banding (or steps) in color gradations by
increasing the total number of gray levels (color shades)
available in the printer. It also resolves many problems
associated with traditional color screening. ColorDepth
screening can provide the equivalent of approximately 120
levels per primary color at 600 dpi—for a total of 1.7
million colors. At a comparable line screen of 100 lpi,
traditional screening is only capable of 37 levels for a total
of 50,653 colors.
