7.6 Metamerism
- 16 -
Metamerism is the three stimulation values are the same but the distribution of the
spectrum is different.
The difference of spectrum distribution can judge roughly the degree of
metamerism for the same color samples. If the shape of spectrum reflectivity curve
between copy and standard sample is almost same and has lots of the cross points
and superposition, which means low degree of metamerism and small color
difference, and vice versa. This is an effective and qualitative way to judge the
degree of metamerism according to the spectrum distributing difference.
Check the records of metamerism by “up/down”.
