The GRAY command determines whether gray in graphic images is represented using
black or combination of cyan, magenta, and yellow.
If each value of the RGB signals is the same, the corresponding area will be achromatic
(grayed). For example, if R = G = B = 0, the corresponding area will be black. If R = G =
B = 100, the corresponding area will be gray. If R = G = B = 255, the corresponding area
will be white, that is, there will be no color components. (White and black are not colors.
They are states in which all the light is reflected and absorbed respectively.)
If each value of RGB is the same when processing images, the corresponding area can be
represented by using either the same quantity of toner or only K toner for each of CMY.
(If C = M = Y, the color is black in theory.) However, the black represented by C = M =
Y is not the same as the black represented by K alone.
When representing an image, for example, if it contains an area represented by R = G =
B, the look and impression of that image will be completely different when it is
represented by CMY and when it is represented by K alone. (Which look is better is
dependent on the viewer's taste, the contents to be printed, and so on.)
The graying process defaults to representation using K toner alone. However, a toggle
switch is provided since, as mentioned earlier, this process cannot be determined
objectively.
This command is irrelevant to models FS-8000C and KM-C830.
