range of colors they can produce. (This information is contained in
device
profiles.) Then, using this information, the CMS maps each
device's color descriptions to the CIE model, which is an international,
device-independent standard for color.
For example, to make a printer’s color output look the same as the
colors on your computer monitor, a CMS translates the monitor’s RGB
colors into device-independent CIE color, and then translates from
the CIE color into the printer's CMYK colors. A CMS can warn you (or
automatically adjust color) when the colors you specify are outside
the output device’s range, and they can show you on screen how the
printed output will look.
The advantages of using a CMS are that you get consistent color
across all devices, and an on-screen preview of output. However,
CMSs are not portable across platforms, they can be expensive, and
they do consume processing time and power at the host.
A few well-known color management systems include Kodak Color-
Flow, Agfa ColorTune, Pantone POCE, Apple ColorSync, Microsoft
ICM, Color Solutions ColorBlind, and Linotype-Hell LinoColor. The fol-

Instructions for installation and use are included on the QMS Soft-
ware Utilities CD-ROM or on the supplemental color disk provided
with the printer.
Color Matching with PostScript Level 2
Your printer's PostScript Level 2 allows it to accept device-indepen-
dent CIE color specification directly (in addition to CMYK or RGB
color specifications). This means that if you have an application that
supports PostScript Level 2 printing (such as Adobe PhotoShop) or if
you use the QMS-developed driver for Windows or Macintosh, your
printer will perform color matching automatically. These drivers work
with the printer-resident color rendering dictionaries to match colors.
