Color Spectrophotometer

Color spectrophotometer :

Of course the fact of dispensing exactly the same volume of colorant in a white base for several tinting systems and then measure the colorimetric values of each application with the spectro will stress the colour strength of the blue colorant for example.
This method is not complete enough to estimate globally the performances of a tinting system. (Watch the information above).


The different steps of the color spectrophotometer are :

  1. Selection of 10 strong shades of reference (yellow, red, orange,…) among a standard colorchart, such as the NCS.
  2. Reproduction of each one of these 10 colours with each one of the tinting systems.
  3. Measurement and comparison of the evolution of the technical characteristics of the liquid coloured paint.
  4. Measurement and comparison of the performances after the application of the coloured paint (opacity, drying time, gloss, aspect in general and Delta E in comparison with the color of reference extracted from the standard).

Comparison of the colour formulae and the global cost (base + colorants) of Color spectrophotometer in relation with the level of opacity you have obtained. You have to compare the cost for the same result of opacity in 2 coats (mainly for dark yellow and dark red shades). And in your global cost consideration, if the final result is not good enough with a traditional tinting system, you have to consider that you will be oblige to manufacture and stock coloured bases in the factory and the retail shops; so consider the global cost of this operation.
