However, in practice, the toners do not have pure color absorption characteristics as shown in Figure 3-

336. In general, Y toner tends to have good absorption characteristics, but M toner tends to have undesirable

absorption characteristics for the B component; and C toner likewise tends to have undesirable absorption

characteristics for the G and the B components (segments enclosed in Figure 3-336). In other words, M toner

if left as it is would tend to have color reproduction characteristics that include the Y component, and C toner

would have color reproduction characteristics that include the M and the Y components.

For this reason, reproduction of red by mixing Y toner and M toner would produce a yellowish red
