About Color Matching
It is important to manage the work processes from data creation to output based on methods
with color consistency. For example, scanners, digital cameras, and monitors, and other
devices express the blending ratio to which the light of red, blue, and green (three colors) have
been added to black as values over the RGB color space (additive mixture of colors).
Meanwhile, printers express the blending ratio of the four toner colors cyan, magenta, yellow,
and black relative to white (white light), with the three reflected colors red, blue, and green
excluded as values in the CMYK color space (subtractive mixture of colors).
The RGB color space and CMYK color space are color spaces dependent on the machine
used, and so when converting color spaces, the colors will be different from the reproduced
colors unless individual machine characteristics are taken into consideration.
To maintain color consistency from data creation to output, it is necessary to consider the color
differences by device when converting colors. This process is called “color matching”. The
program that implements the color matching is called the “color management system” (CMS).
The printer can use either printer driver color matching or application color matching.
Note: Even if you are using color matching, the printed colors may appear dark compared to
the colors on the monitor. This is because the range of colors that can be reproduced by the
device is narrower than the range of colors that can be reproduced by the monitor, so even if
color matching is used, the vivid colors on the monitor cannot be reproduced.
