4. Colorimetry

In order to determine colours, the CIE system was developed (as explained in the previous chapter). In order to be able to measure these colours, it is necessary to represent them with numbers, and there are several procedures available:

The Densitometer


Densitometry makes is possible to produce standardized results, which is very important. But how does a densitometer work? How does it determine and measure col... 

The Spectral Photometer


In order to measure colours very accurately, it's better to use a spectral photometer instead of a densitometer. It is much more precise.
