MINOLTA-QMS’ Color Control System also offers several

ways for performing color matching. The process of color

matching makes sure that color is reproduced as faithfully

as possible on all devices. Monitors and printers interpret

color differently. Scanners and monitors use RGB (red-blue-

green) values to define colors. Printers use CMYK (cyan-

magenta-yellow-black) inks to print color. Color matching

methods attempt to reconcile the differences between these

two color models.

When an image is scanned into a computer, it is sent by the

scanner in one RGB format and converted into another RGB

format by the computer. When it is sent to the printer, it is

then converted into CMYK colors by the printer driver or

application. Color output on the printer may be dramatically

different from the colors on the monitor screen.

To alleviate this inconsistency, color management software

is available that describes colors for the scanner, monitor,

and printer in a common language. This is done by map-

ping each device’s color definitions, or color space, to the

CIE international standard for color.

The CIE color standard, first developed in the 1930’s, stan-

dardizes the system for measuring color perception by the

human eye. This is a device-independent way to specify

color. In addition, the magicolor 7300 supports the ICC

International Color Consortium standard that incorporates

the CIE standard for color and the use of device profiles.

To define a device’s color space, the color matching system

uses a device profile to determine an independent value for

each color. A device profile contains a description of the

range, or gamut, of colors that a device can produce. When

a color from one device (i.e. a monitor) needs to be trans-

lated for another device (i.e. a printer), the color manage-

ment system’s color matching method (CMM) software first

translates the RGB color to the CIE standard and then

makes the translation to CMYK. This translation is called

color transformation, and maps color from the monitor to
