Résumé : |
Modelling programs allow us to crate custom materials and can be configured to match a colour measuring instrument so that a pigment can be correlated back to the model. |

- Fig. 1 : Reflection curves for thin film interference from a single thin film of RI 2.5
- Fig. 2 : Reflectance curves for various substrate thicknesses coated with 80 nm RI 2.5. The average of these curves is equivalent to the 80 nm single film curve from figure 1
- Fig. 3 : Colour distribution for various substrate thicknesses coated with 80 nm RI 2.5
- Fig. 4 : Hypothetical cumulative intensity of the reflection interference spectrum of the 1st layer and the 3rd layer compared with the actual reflectance interference spectrum for the three-layer stack depicted on the right
- Fig. 5 : Colour travel plots from 0 to 70 degrees comparing low and high refractive index
- Fig. 6 : Colour travel plots from 0 to70 degrees comparing single-layer with multi-layer
- Fig. 7 : Reflection curve for a multi-layer structure showing higher chroma compared to a single layer
- Fig. 8 : Colour travel plots from 0 to 70 degrees, comparing different thicknesses of the low refractive index layer
- Fig. 9 : Colour travel ploots from 0 to 70 degrees, comparing different thicknesses of both high refractive index layers |
