Elrepho 3000
Values for this task can be computed with any of the following
illuminant/observer combinations: A/2°, A/10°, C/2°, C/10°,
D50/2°, D50/10°, D65/2°, D65/10°, D70/2°, or D70/10°.
The reflectance factors will be labeled Rx, Ry, Rz.
A single measurement is required to compute DIN53140
reflectance.
ISO Brightness R457 (TAPPI 525, SCAN-P3:75) (3100
and 3300 models)
The computed value will be labeled “R457”.
A single measurement is required to compute ISO Brightness R457.
ISO Brightness Difference Δ R457 (3100 and 3300
models)
The computed Difference will be labeled ΔR457.
A single measurement with the UV radiation included and one
measurement with the 420nm UV cutoff filter in position.
Paper Tasks(cont)
Diffuse Opacity (DIN 53146, TAPPI 519) (3100 and
3300 models)
Diffuse Opacity can be computed with any of the
illuminant/observer combinations supported by the DIN53140
reflectance factor computations.
The results will be labeled “O” when displayed.
