Experience in assessing whiteness and industrial requirements is considered in the selection of whiteness formulas. The problems set by the photometry of fluorescent samples and the calorimetric prerequisites delimit the choice. A standard whiteness formula of neutral hue preference is proposed. Two supplementary whiteness formulas of green and red hue preference, respectively, are added. The feasibility of a complete characterization of white samples by whiteness, tint, and luminance factor is discussed.
在白度公式的选择中考虑了评估白度的经验和工业需求。荧光样品的光度学问题和量热学前提条件限制了选择范围。提出了一种偏好中性色调的标准白度公式。分别增加了两种偏好绿色和红色色调的补充白度公式。讨论了用白度、色调和亮度因数完整表征白色样品的可行性。
