Bibliography
Gives a measuring method for the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss. Does not apply to coloured papers or boards which incorporate fluorescent dyes or pigments. May be used when determining the colour of papers or boards that contain fluorescent whitening agents providing the UV-content of the illumination on the test piece has been adjusted and conforms to that in the CIE illuminant C with the use of a fluorescent reference standard given by an authorized laboratory which is described in ISO 2470.
