(6) UCR (Under Color Removal)

Principle

Getting the right colors using YMC toner addition does not always work

perfectly. For example, if for each color (YMC) the same quantity of toner is

put on the paper, ideally the image should become black, but in reality it

becomes a dark color, such as dark blue.

To compensate for this, an equal portion of the common ID value for each

color is subtracted. This reduces the amount of color toner on the paper, and

a proportional amount of black toner is added. This process is known as

UCR.

The UCR ratio is the percentage of the common ID value for YMC that is

subtracted and converted to Black. In the above example, where the UCR

ratio is 100%; the entire common ID value is subtracted from Y, M, and C,

and converted to Bk.

In actual use, the UCR ratio depends on the color mode and the image

density. For example, when the UCR ratio is 95%, 95% of the entire

common ID value is subtracted from Y, M, and C, and converted to Bk.
