Color rows
The corresponding RGB values of the OCA colors were con-
verted to sRGB. These are the same color values as those in the
first color row with the scale of 0 to 1.

DeviceRGB
Here the four color stations are accessed directly. They are sent
color values on a scale of 0 to 1. In contrast to RGB, a "1" indi-
cates maximum coloration ("black" for all color stations), while
"0" represents maximum brightness. The gray field is not repre-
sented as "composite gray", but rather using only K values
(black).

DeviceCMYK
This color row represents its color fields in black/white or
grayscale, where "S" indicates the saturation (corresponds to
the K value).
The values for "S" are derived from a formula that converts
colors to gray values: S = 0.299 * R + 0.587 * G + 0.114 * B.
If the printing system is switched to back/white mode, the same
result as in the other color rows should be achieved in this row,
in as far as possible.
