    Traceability of 0:45 Colorimetric Values for Standard Whiteboards

    • This paper combines the physical definitions of 0:d diffuse reflectance ratio and 0:45 diffuse reflectance factor and proposes a conversion formula between them according to the difference of geometric conditions in the diffuse reflectance model. Furthermore, a method is proposed to calculate the 0:45 diffuse reflectance factor from the 0:d diffuse reflectance ratio and the relative radiance factor of a standard whiteboard to obtain the 0:45 chromaticity and whiteness values of a standard whiteboard, which is successfully traced to the chromaticity primary reference and transferred to the comparison results of BIPM.CCPR-K5.
