2+ can purchase this optional host-based software, Southwest Software’s Color-
Encore for
magicolor printers, that requires the use of a densitometer (not included) to
perform calibration. Refer to ColorEncore’s software documentation for installation
and usage.
Once 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 QMS
magicolor 2+’s primary toner densities to
factory levels.
To calibrate the magicolor 2+, select the magicolor 2 calibration sets in ColorEncore.
Colorific is monitor calibration software that ships with the magicolor 2+. 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 2+. 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.
QMS Q
COLOR
provides a preset AM halftone setting, referred to as QMS ColorDepth.
ColorDepth is designed to eliminate rosette and moiré patterns, (or steps) in color gra-
dations by increasing the total number of gray levels (color shades) available in the
printer. It also resolves many problems associated with traditional color screening.
QMS Q
COLOR
screening can provide the equivalent of approximately 120 shades per
primary color at 600 dpi—for a total of 1.7 million colors. At 1200 dpi, ColorDepth pro-
vides approximately 200 shades per primary color for contone-quality images.
