In generally, color measurement is based on photo integral colorimeter, and densitometer based on color filter. Densitometer is applied in the printing trade, and the color denstiometer still rest on development and research in our country.
在工业生产中，颜色测量一般是基于光电积分式的色度仪，密度计大多应用于印刷行业，且彩色密度计在国内基本上还是停留于研究阶段。
