CIE whiteness of paper or paperboard
The CIE whiteness test measures the whiteness of paper or board under the CIE D65 daylight standard.
The method gives the complete visible spectral range (VIS) information about whiteness, unlike the ISO (ISO 2470) method, which operates only in the blue light region. The test is not suitable for colored papers with fluorescent dyes.
