consistent and stable toner densities from day to day, and from one supply change to
the next, to ensure predictable color.
QMS offers an alternative method for color-calibrating the
magicolor
6100: optional
instrument-based calibration software—Color Encore. Owners of the
magicolor
6100
can purchase this optional host-based software, Southwest Software’s ColorEncore
for
magicolor
printers, that requires the use of a densitometer (not included) to per-
form calibration.
Once Color Encore is installed, users simply print a target page from the software
application and measure the page with the densitometer. The measurement results
are used by the software application to return the
magicolor
6100’s primary toner den-
sities to factory levels.

Colorific is monitor calibration software that ships with the magicolor 6100. This soft-
ware, which is available for both Windows and Macintosh operating systems, allows
you to calibrate your monitor to a standard monitor profile that is supported by the
CMM built into the
magicolor 6100. For best monitor to printer color matching, Colorific
software must be used to calibrate the monitor. Once the monitor is calibrated, the
printer’s built-in ICC color matching, when set to sRGB source data, ensures that
printed output matches the monitor. For more information concerning the use of the
Colorific software, refer to the instructions that were provided on the
QMS Software
and Utilities CD-ROM.

Line screening and halftones are factors that highly influence color image rendering.
In conventional printing, color images are composed of tightly arranged dots (or half-
tones) 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.
The technology behind the QMS Q
COLOR
halftone screening used as the “Standard”
setting in your
magicolor
6100 is an AM halftone setting, referred to as QMS
ColorDepth. ColorDepth is designed to eliminate rosette and moiré patterns (or steps)
in color gradations by increasing the total number of gray levels (color shades) avail-
able in the printer. It also resolves many problems associated with traditional color
screening. QMS Q
