Din6167 Yellowness; Additive Metamerism; Multiplicative Metamerism; Paper Tasks - Datacolor Elrepho 3000 Manual

Elrepho 3000
This index is always computed with the C illuminant and 2°
observer.
The yellowness value will be labeled with "YI".
A single measurement is required to compute D1925 Yellowness.
DIN6167 Yellowness (3100 and 3300 models)
This index can be computed with either D65/2°, D65/10°, or C/2°
illuminant/observer combinations.
The yellowness value will be labeled with "G" .
A single measurement is required to compute DIN6167 Yellowness.
Additive Metamerism Index (3300 model)
This index supports all illuminants and the computed value will be
displayed as "MI".
Measurement of both a standard and sample are required to
compute Additive Metamerism Index.
Multiplicative Metamerism Index (3300 model)
This index supports all illuminants and the computed value will be
displayed as "MI".
Measurement of both a standard and sample are required to
compute Multiplicative Metamerism Index.
