Descriptions
In this example, the UCR ratio is 70%.
For a Black Image
When copying a black image, the ID values for all colors are equal (figure 1). For
each color, the ID value is reduced by the amount of the UCR ratio (70% in the
example). A black ID value equal to the 70% reduction is added to compensate for
the color ID reduction (figure 2).
For a Color Image
When copying a color image, the color ID values differ from one another (figure 3).
It is treated in two steps.
The ID value for this image is broken down into two parts (figure 4): a set of values
equal to the lowest color ID value, and the remainders of the two higher values.
The part with equal values is treated as a black image (see figures 1 and 2), using
the 70% UCR ratio. The resulting amounts are then added to the remainders from
step 1 (figure 5). The result gives us the ID value for each color and for black
(figure 6).
